Hi. I'm Mike Green. I'm one of the owners of 1AAuto. I want to help you save time and money for repairing and maintaining your vehicle. I'm going to use my 20 plus years of experience, restoring and repairing cars and trucks like this, to show you the correct way to install parts from 1aauto.com. The right parts installed correctly. That's going to save you time and money. Thank you and enjoy the video.

In this video, we'll be replacing the front hub on this `98 Explorer with four-wheel drive, the same as a `95 to `01 Explorer Mountaineer and Sport Track. The tools you'll need for this are jack and jack stands, various millimeter sockets including a 32mm socket for the center hub nut, a hammer, screwdriver and pliers and you will also need a torque wrench that can go up to 150 foot pounds.

Okay, so obviously you're going to want to jack up and secure your vehicle. You just work a screwdriver in there and pry off your cap. Okay, if you don't have an impact wrench, you want to remove the center hub nut when your car is still on the ground. You'll need a 32mm socket, and probably a big breaker bar; I have the luxury of an impact wrench so I'm going to use it. Okay, we will leave the hub nut on there for now. So now, I'm taking the wheel off and take the brakes apart and these are 19mm. If you don't have impact tools, loosen your lug nuts on the ground, then raise your vehicle and secure it with a jack stand and then remove the lug nuts. Once the lug nuts are off, the tire right off. There's four bolts, okay, that basically hold the brakes on. There's one here, 13mm and one up here. Okay and those just hold the calipers to this big bracket. There's also a 15mm bolt here and a 15mm bolt right up here.

Okay, so we're just going to speed through removing those four bolts. You pull the caliper up and off and you can wire tie it up top and then that bracket comes off with the 15mm bolts and we'll pick it up from there. Okay, this bracket, that comes right off and your rotor comes right off. Okay, you are going to want to take off this dust shield and its 8mm bolts. When I filmed this, I did it out of order. You want to take off the backing plate, unbolt the hub, and then remove the hub, and disconnect the wire harness and I did it, like I said, out of order. You're going to see some things appearing and not appearing at different times there during the video

So remove the three 8mm bolts that hold the backing plate on. Okay and here, I used a 5mm Allen wrench to undo this bolt which then you can unplug your ABS harness. You could do it that way or you can pull the harness off with the hub. The correct tool to use, which I'll show you is an axle puller. What I like to do is sometimes they're easy, so smaller hammer, not a huge hammer. Okay and I still have the bolt on here. I'm just going to watch the bolt. I'm going to give it one good whack. You don't want to pound on this. You don't want to beat it with a big sledgehammer because you could ruin your CV joints but giving it one good tap with a good hammer won't hurt the CV joints and if it breaks away it makes your life a whole lot easier, and it did it. It actually broke right away which is good, most of them do.

Okay, to quickly re-summarize what I did there. I just used the hammer. I watched the axle closely, gave it a good whack and if you can see, the axle removed in relation to the hub then you know it's broken loose. Okay now if it hadn't broken away. I would have used this two-jaw puller, go over like that. Okay and I'll just push it right through. You'll see it's pushing the axle right through. Once you know you have the axle broken loose then there's three bolts right back here, one, two and then if you pull, you're steering around, the third bold is right in there. You can see the other right here. It's probably a good idea to spray a whole bunch of penetrating oil on them and let that sit for a little bit.

These are 15mm bolts. Make sure you get your wrench on that good and tight. Actually, it usually come without too much problem. I'm not even using that big of a bar. Yeah, but you may notice here that I do trade in my smaller bar for a larger breaker bar to get the other two bolts out. I could also hook a piece of pipe or just take a piece of pipe and put it around the end of your ratchet and that gives you more leverage as well.

Okay, what you can do is before you get the bolts all the way out, you can give the bolts themselves a whack. It usually sometimes tends to break the other way but if you have to, you can just resort to, and then from right here and that breaks the hub away from the steering axle.

Okay, get the bolts all the way out. Then there's my hub off the truck. Okay, so now in preparation to put the new hub on. I do want to remove this harness because the new hub comes with one. There's an 8mm bolt here and then you just need to pull up a couple of pins out of the frame there and then it unplugs right here. Then the other thing is I'm going to just take a screwdriver and a wire brush and just kind of clean that out a little bit. We're just going to fast forward here as I pull out that 8mm bolt and then I use pliers and screwdrivers and whatever to get the clips out of the frame for the ABS harness. Basically, I break some of the clips and then just pry them out.

Okay, when you that pull off, you just ... you feel for this little tab right here, press, and fold it. Okay, so you have the worn out on the old hub. Everything's all the same. It's got the harness on it, which I did disconnect from the original, got a bolt all in there. The harness does point towards the front then you're going to have to put it on, get it into the axle, push it right on there and force the bolts through the start, got that one started. Got that one started.

Okay, we'll speed things up here as I just take those three 15mm bolts, and work them into the back of the hub and snug them up. I got my torque wrench set to 70-foot pounds and then make sure it's on that bolt fairly well. Okay, I torque all three of them up to 70-foot pounds. Okay, so fast forward, torquing those other two bolts and then re-install your wiring harness. Clip everything to the frame and make sure you hook it back up.

Okay and we're fast forward, putting that brake shield back up and tightening up those three 8mm bolts. Okay and we'll also fly through putting the brakes back together and your wheel back on. Just the first time you drive your car, just be very careful. You've worked on the brakes. You've worked on the steering. So make sure your car is stopping before you go fast and make sure that there's no looseness or anything in the steering before you road test it.

If you do want to see putting your brakes back together in regular motion, just check out our front brake video.

Put the wheel back on. Put your lug nuts on, get them snug, then lower the car to the ground. Torque them up to 90, to 100-foot pounds. Torque up this hub nut and it calls for a 157 to 213 foot pounds of torque. My trusty torque wrench here will set to 150 pounds. I'm going to torque it to 150 and then just pull it another couple of inches or so. Okay, now I can put the cap back on. I need to put the single thing right up here, where this leak is.

In this video, we're going to be working with our 2006 Ford Explorer. We're going to show you how to remove and replace your vehicle's sway bar link in the front. If you like this video, please click subscribe. We have a ton more information on this and many other vehicles. If you need these parts for your car, you can follow the link down into the description over to 1AAuto.com. Here are the items you'll need for this repair.

Using a 19mm socket and a breaker bar, loosen the lug nuts on your tire. Raise and support your vehicle. We're doing this on a lift to make it easier to show you what's going on, but this job can be done at home on a jack and jack stands. Finish removing your lug nuts. You should be able to do this by hand at this point but you can use a ratchet if you need to. You can then remove your wheel and tire.

It may be a good idea to apply some penetrating oil to whatever parts you're going to be working with. Put a 17mm wrench on the nut on the top side of your sway bar link and brace it against the frame of the vehicle. You can then use a 16mm socket and ratchet on the bottom to loosen it. The sway bar link on these vehicles is essentially a series of bushing and washers with a sleeve all held together by one long bolt, as opposed to being a one-piece unit like some other vehicles.

You can see ours is pretty rough here, because there's usually not this much slack. That's actually what your bushing is supposed to look like on all four pieces, one on each side. You can see the old ones are worn down or cut there. It looks like they've actually fallen off over time. Once the nut's out, you can try to remove the bolt from the center of the sway bar link. This can be pretty difficult, so if it doesn't come out by hand, don't be afraid to get on there and give it a good hit with a hammer. The sway bar link will disassemble just like that when you pull it out, so just make sure you have all the old bushing material and all the old washers off of it.

Now you sort of need to build the sway bar link into the truck, so we'll start with a washer and then a bushing. We'll go up through the control arm, install a bushing with the tapered end down, followed by another washer, the sleeve, a washer with the cup end facing up, and a bushing with the tapered end facing up. We'll go through the sway bar, install another bushing. You may need to use a screw jack or floor jack to jack up the control arm to get enough slack on that bolt to install the sway bar link. Then install the washer and a nut and tighten your new hardware down. You'll want a 17mm wrench on the nut and a 16mm socket and ratchet on the bolt end. Just tighten that up until it compresses the bushings so you know that everything's nice and tight and there's no slop in there to make any noise when you go over bumps. Once that's down tight, you can lower the weight off of the screw jack or floor jack.

Reinstall the wheel and tire onto your hub. It's easiest to put a lug nut inside of the 19mm socket to start it onto the studs. Get all five of these down as tight as you can by hand, and then we'll torque the wheel once there's some weight on it. Lower the vehicle back down and put partial weight onto the wheel and tire. This means that you may have your jack or lift under the vehicle. Get the tire to touch and let the vehicle come down some without allowing it completely off of the lift or jack. Torque your lug nuts to 100 foot-pounds in a cross pattern.

Brought to you by 1AAuto.com. Your source for quality replacement parts and the best service on the Internet. Thanks for tuning in, this is Part Two of a two part series. We're going to go through reinstalling your lower ball joint on this '97 Expedition. This procedure is similar for a whole bunch of different Ford trucks and SUVs. Here's a list of tools that we used on this Expedition. If you have a different vehicle some of the sizes may differ and one thing that is not on here, you will want a grease gun to grease up the ball joint after you install it.

We've got our control arm here. We're just going to put it right on there like that. Our ball joint, our collar and then that's going to go up and in. We put our press on there. I'm going to speed it up here so we use the press to push the ball joint up and in and you do this in two steps. This first step is just going to get the top of the ball joint flush with the top of the control arm. We're going to take this boot off. Now with this ramp here on top of it. I'll fast forward here again as we use that press to push the ball joint the rest of the way up into the control arm until it's nice and tight, the bottom is nice and tight against the bottom of the control arm and then put your protective boot back on. Now you want to lock it in place with a snap ring. You can get this on without snap ring pliers, but they certainly are a help. Just get this set up.

What I'm going to do is I'm just going to thread the nut on a little bit and then use a hammer to kind of knock the ball joint outward, that helps make it easier to get the other and just keep that protective boot up on there. That's just going to allow your knuckle down on there, your knuckle up, take your jack out of the way. Lift it up on the knuckle and bolt. Okay, I'm going to speed through putting the half shaft back in. One thing I did forget to do, I do a little bit later, is now is the best time to put the grease fitting on top of the ball joint, before you put that axel in there, but put the axel in place to get it into the hub and then get it lined up on the axel and start a couple of those 13 mm bolts. Once you get all the bolts in you want to torque them to 60 foot pounds and what I do is I use a black marker.

I mark the head of them after I torque them. Then you want to kind of go to the opposite side, torque the next bolt, mark it and just keep going until they're all torqued. I'm just putting the tie rod back on. Just put the nut on there and keep it in place. Now we want to tighten the ball joint nut to 98 foot pounds and that's for this '97 Expedition. It could be different for your vehicle. Okay, I put our cotter pin through, bend it down and around. I'm going to fast forward through putting the grease fitting on top. Like I said earlier a little bit easier to do this step before you put the axel in. Then continue to fast forward as a put a grease gun onto that fitting and fill the lower ball joint with grease. Okay, I'm going to tighten my tie rod nut to 60 foot pounds. Next the cotter pin through, bend it down. Here I'm going to install this sway bar link. I've already put a new link on the other side, then just started the nut on it. Bushing, the bushings always go towards the metal.

Okay, so I've got a bushing on the bottom going up to the mount control arm and a bushing above that. Then my shaft goes on there and then the washer, then the bushing pushing down and in. Make sure the bushing is centered in the stabilizer bar unit. Now bushing and washer, then my nut. Now you'll want to use your jack to put some pressure on the suspension and then tighten up the stabilizer to 15 to 17 foot pounds. Then we'll put on our center hub nut. We're just going to tighten that preliminarily. We're not going to torque it until the wheel's back on. Now you can let your suspension back down and you want to re-tighten your torsion bar and since we marked it we can tighten it right back up to where it was before. You can put your tire back on and start each lug nut one by one. Make sure you don't cross thread them. Tighten them down preliminarily. Torque the lug nuts to a hundred foot pounds using a star pattern. Okay, now using a 35 mm socket torque your lug nut to 220 foot pounds. Put the retainer back on and then the cotter pin, then your wheel cap. We recommend you have your alignment checked and adjusted if necessary.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks!

In this video, we're going to show you how to replace an outer tie rod on this 2003 Mercury Mountaineer. We show you on the passenger side, but the driver side is the same procedure. The items that you need for this is a new outer tie rod from 1AAuto.com, a 7mm, 19mm, and 21mm socket and ratchet, a piece of pipe for some extra leverage, two adjustable wrenches, a pair of pliers, a hammer, a tape measure, jack and jack stands, and a torque wrench.

Pry off the hub cap by using a flat blade screwdriver in the small slot on the side. Once you get it started, you can just pull out around the edges. If you don't have the benefit of air tools, you'll want to start with the vehicle on the ground, loosen the lug nuts, then raise and support the vehicle on jack stands. Remove the lug nuts, wheel, and tire the rest of the way.

There's a small indent on the inner tie rod. Put the tape measure there and measure out to the center of the grease fitting, which is 9-1/16" in this vehicle. Then, just bend off the legs on your cotter pin on the bolt. Then just pull the cotter pin out with a pair of pliers. Then, using a 19mm socket and ratchet, just remove this nut. Spray this nut with some penetrating oil, and then, using two adjustable wrenches, just separate it. Once it turns, it's loosened up, and you can hammer your wheel knuckle until you see the outer tie rod move. You can see it move right there.

Now you can pull it up and out of the knuckle and twist off the outer tie rod. Up top is the old outer tie rod, and below it is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same.

For lineup purposes, ideally what you want to do is be able to remove this without turning the inner tie rod. Our bolt or nut didn't come loose. That's not a big deal, but it does mean that we will need to take this and have it aligned because we did turn the inner tie rod a little bit, but we can still put it back together. We'll fast-forward as Mike twists on the new outer tie rod. Remove the nut and then line up the outer tie rod with the hole on the wheel knuckle. You may need to move the wheel knuckle around a bit until it goes down in place. Once you get it in, replace that nut and then just tighten it up. You want to tighten this to about 50 foot-pounds. Once it's fully tightened, make sure the hole lines up with the castle nut, and you may need to turn it a bit more so that it lines up, and then just push your cotter pin through and bend the tabs in opposite directions.

Tighten that nut back on to the outer tie rod using your two adjustable wrenches. Put in your new grease fitting and tighten it up with a 7mm socket and ratchet. Now, just add a few squirts of grease into the grease fitting. Replace your wheel, and then replace all the lug nuts and tighten them preliminarily. Then, you'd want to lower the vehicle and tighten them the rest of the way and torque these in a crossing pattern to 100 foot-pounds. Replace your hub cap, and we recommend you have your front alignment checked and adjusted if necessary.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the front sway bar link on this 2003 Mercury Mountaineer, same as any 2002 to 2005 Mountaineer, as well as Explorer. Our front passenger side is broken, so we show you how to get it out and replace it with a new one from 1A Auto. You'll need new sway bar link from 1AAuto.com, 16mm and 19mm socket and ratchet, a piece of pipe for some leverage, jack and jack stands and a torque wrench.

You'll want to remove your center cap. If you don't have the benefit of air tools, then loosen your lug nuts with the vehicle on the ground. Then raise both front wheels and support the car with jack stands and then remove the lug nuts and wheel the rest of the way. Now you can pull the wheel free.

This is the driver side, which is actually still together, so you would, if you're removing one that was still together, put a 15mm socket and ratchet on top and a 16mm wrench on the bottom, remove that top nut and then go from there. On ours, it's broken so I'm just filling, basically, the cavity with penetrating oil. This is pretty typical: it breaks off up top here and you saw where you just filled it up with penetrating oil and now we're just messing around with it. We locked some locking pliers onto it. That penetrating oil really helped the bolt start up and we've basically broken the plastic here. Now this plastic tube will slide off.

We're just going to use a hammer and chisel to remove the rest of the plastic. This, of course, is the worst case scenario, you just want to remove the plastic, you can use some locking pliers and then just remove the nut on the bottom or at least loosen it up as much as you can. Then just hammer this down and out.

Before installing it, just jack up the other side, just slightly. Now replace your sway link and the order it should go in is: washer, bushing, control arm, then bushing, washer, the tube, and another washer, and then the bushing, and then your sway bar, then another bushing, another washer, and then the nut. You just want to tighten that nut preliminarily,and then release the jack.

To tighten up the link, what you want to do is have the car back down on the ground, and now I have a jack supporting just the front suspension so that basically everything is level and the suspension is in its correct ride height. Then tighten up the link by holding the wrench on top and then turning the bottom. Tighten it up so that the bushings are all squeezed to about the diameter of the washers.

Replace your wheel, then replace all the lug nuts and tighten them preliminarily. Then you'd want to lower the vehicle and tighten them the rest of the way, then torque each of these in a crossing pattern to 100 foot-pounds. Now replace your hubcap. Just line it up and hit it back into place.

I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts, installed correctly that's going to save you time and money. Thank you and enjoy the video.

This video is part one of a two-part series, replacing the ball joint in this '97 Expedition. In this video, we basically detail removing the old ball joint. This is the same for all the Expeditions, F150s, Explorers, a whole bunch of the Ford trucks and SUVs from this era.

Here's a list of the tools that we use on the Expedition. If you're doing a vehicle different from the Expedition, some of these sizes may differ. You will need heavy-duty tools. You're not going to want to try this with the 20-piece set Uncle Joe gave you for Christmas. This is heavy work. You'll need jack and jack stands, metric sockets 13-27 mm, standard sockets 1/2 inch to 7/8, you'll need a 35 mm socket, a 12 point 13 mm socket, ratchets extensions and a breaker bar or pipe because you will need to get some leverage on some of those bigger bolts and things, pliers, hammer, a heavy punch, ball joint removal tool, ball joint press, large flat blade screwdriver, and a paint marker or a old can of spray paint. The ball joint removal tool I'd recommend if you're going to be doing a lot of your own work. It's a pretty affordable tool to go out and get. Ball joint press might be something that you want to borrow.

Obviously, you're going to start by removing your cap. If you don't have the benefit of air tools, what you'll want to do is start with your wheel on the ground. With your wheel on the ground, there are probably three things you're going to want to do. Loosen your lug nuts. Then there's a 35 mm bolt in the center that holds the axle into the hub you're going to want to take the cotter pin and the cover off of that and loosen that 35 mm bolt. Also, go underneath and there are seven 13 mm 12 point bolts that hold your axle to your front drive. You'll want to just loosen those seven bolts. Much easier to loosen all these bolts with your tire on the ground held in place if you don't have all the tools that I have access to. You're going to want to loosen up your torsion bar. Your torsion bar is actually your spring. This is what supports the vehicle. I'm just going to take a little silver spray paint ... That way, when I back that bolt out, I'll know where it originally was.

Using an 18 mm socket and a ratchet, I'm going to loosen the torsion bar tension nut, or bolt, and you can basically pull it all the way out and then just turn it back in a few turns. You just want to loosen it up and take as much tension off the torsion bar as you can. You can see as I'm done, you can see where there's no paint on the threads, that that is how far you would want to retighten it. Now we're going to undo our tie rod end here. I'm just going to speed it up here. The cotter pin's very rusty, so first so first I break it with the pliers. Then I use a hammer and punch and just kind of keep working and breaking small pieces off until I can drive it through and out of the tie rod end. Now I'm pounding a 21 mm socket onto that nut because it was quite rusty. I just want to make sure I get a good socket that gets a good grip on it.

I've got a bar on here. Put a piece of pipe on it for some more leverage. Hopefully it comes apart. Just fast forward here as I switch over to a ratchet and remove the nut the rest of the way. Here I'm going to put a tie rod, it's a tie rod and ball joint tool, but obviously I'm using it to do a tie rod right now. By using this tool, I can assure that I can just reassemble my tie rod. I won't damage the tie rod by removing it this way. Next, I'm going to remove the stabilizer link, so I'm going to spray the top of it with some penetrating oil and let it sit for awhile. These stabilizer links are sometimes difficult to get apart. You can use hand tools. They will come apart. I just chose to use a impact wrench just to make it easier. I have a 9/16 socket on the bottom and a 14 mm socket on the top.

Use a hammer and pound down on that bolt. Then use a punch, see if you can it to go down through the sleeve. I end up actually having to use vice-grips and a wrench. Obviously, you also want to remove the other side so you can move your stabilizer bar around easily. What I'm going to do here, put set of vice-grips onto this shaft, tighter here. Now we're going to remove the half shaft of the CV axle. As I said in the beginning of the video, these are the bolts that if you don't have all the tools that I have, it might be easier to just loosen them while the vehicle's on the ground. You can see I use a big, large crowbar to hold the hub in place while I'm loosening those bolts.

You can see I spin it, loosen one of the bolts, spin it some more, loosen another bolt. If you were actually doing this with your vehicle on the ground, you'd have to probably loosen one or two of the bolts, then roll your car a little bit, put it in park, put the emergency brake on, loosen a couple more, and keep repeating that process.
Once it's unbolted, pull it down and off. I use a pair of pliers and either break off the ends or just straighten out the cotter pin and pull it out. Okay, 35 mm ... As I said in the beginning, if you don't have impact tools and this is easier with the tire on and on the ground, your other option would be to have a helper hold the brakes while you remove it.

What I do is give it one tap and just watch it, see if it moves. Actually, it moves pretty freely. You can pull your stabilizer bar up and out of the way. Pull your axle down towards the front. Then push it, lift it up, push it out. I've got the vehicle support under the frame. Then I've got my jack right under the control arm. You can see there is the bolt for the ball joint, and then there's the jack. I have a piece of the wood on there so I can easily access that ball joint bolt, as well as get a puller on there. Now I can jack it up. You can see, without that torsion bar tightened, the suspension travels here very easily.

Now I'm going to use pliers to break off and remove the cotter pin from the lower bolt. It ends up being kind of a rusty mess, so I actually use a hammer and punch and pretty much just break it away as much as possible so I can get that bolt off. Now a 27 mm socket put it on there, use a little hammer, make sure it goes all the way on. Got a breaker bar on there, actually you're going to take piece of pipe, put it on, give me some extra leverage. It's coming loose. Just one note here: It will help if you take your tie rod and put it back into the steering knuckle and just put the bolt on. That tie rod will hold things in place while you loosen that ball joint nut.

Just speed it up as I change over to my ratchet and take that bolt most of the way off. While my bolt's still on there, take my ball joint removal tool- This just, doing it this way, allows you to break it free without things falling down. Finish removing this bolt. Get your control arm on up. Pull the steering knuckle down and off.
There's a snap ring that holds the ball joint in place. You can use snap ring pliers. Mine was pretty rusty so I used a screwdriver and a hammer to just kind of pry it off and pop it off.

Now you're going to take a ball joint pulling tool, put the collar up on there. With this particular press use a 7/8 socket, put one on top there, and just tighten down the press. Traded my ratchet handle for my breaker bar. I'm going to speed it up here. What I did there was I created a whole lot of pressure by tightening it down. Then I used a hammer, gave it a good whack that kind of broke it free, and then the press just works it the rest of the way out. There's my old ball joint out.
Good a place as any to end it. Check out part two for the reassembly.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the lower ball joint on this 2003 Mercury Mountaineer. We show you on the driver side, but the passenger side is the same procedure. It's the same part and similar process on these Mountaineers from '97 to 2010. The items you'll need for this are a new lower ball joint from 1AAuto.com; 15, 18, 19, 21, 24 and 30mm socket and ratchet; a piece of pipe for some leverage; pliers; snap-ring pliers; a flat-blade screwdriver; hammer; ball joint press; torque wrench; jack and jack stands, and locking pliers, depending on the condition of your sway bar link.

Start off by removing your hub cab and then remove these 19mm lug nuts. If you don't have air-powered tools, you want to loosen them up while the vehicle's on the ground, then jack up the vehicle and support it, and then loosen the lug nuts the rest of the way. Once you've removed those, you'll be able to pull it free.

Now, you want to break off the ends on the Cotter pin right here underneath your wheel knuckle and then you can either hammer it out with a punch or, if the Cotter pin is only sticking out on one side of the castle nut, you can actually just use your 24mm socket and ratchet to break it free. Then, just remove that nut and then put it back on just a few threads.

Remove the nut on the end of the axle and, obviously, if you have air-powered tools it's not a problem. You can have somebody hold the brakes and use a socket and breaker bar if you need to. You want to twist this nut back on until it's flush with the axle and just hammer it until you can see it move. Then come up here and just remove this 18mm nut. With that nut twisted on, again, just a few threads, hammer the wheel knuckle until it drops down. Then, using a 15mm socket and ratchet, you want to remove the nut at the top of your sway bar link. You can hold the bottom with a wrench if it's turning. You can see ours is turning and, in an ideal world, this would just loosen up and you could pull it down, but the top of ours just breaks off.

To help get it out, you want to jack up the other side of the vehicle, and this will lift the sway bar on this side, allowing you to get to the top of sway bar link easier. We'll just spray it with some penetrating oil. Then, using locking pliers, you want to hold onto it while twisting the nut on the bottom of the sway bar link. You'll notice that the plastic will start breaking away and that's fine. You just want to keep repeating the process until all the plastic is gone and you have better access to it. We'll fast-forward as Mike does this. When it gets to this point, you'll be able to remove it and slide it down and out. If it is jammed up, just use a hammer.

Now disconnect your tie rod end, so remove the Cotter pin from the tie rod and I break off the bent over section. I just break it off and then I'm able to pull out the rest of the pin. Then, a 19mm socket, ratchet and a breaker bar loosen it up. You want to take the nut all the way off and then just thread it back on a few threads. Then hit the steering knuckle with a hammer until it pops free. Remove the nut and take the tie rod off and set it aside. If the nut is still on the lower ball joint, hit with a hammer to break it free.

Now support your lower control arm. You can see I have jack stands underneath the frame in the front for both sides. Jack that up with a jack. Here again, make sure the axle is free. I'm not hitting that hard. You don't want to hit your axle too hard because you could damage the CV joints. I'm really just tapping it. Jack it up a little further and now just lift up on the steering knuckle and remove the nut from the lower ball joint. Now remove the nut at the top of the wheel knuckle and pull the upper control arm out of the knuckle.

Take the axle out. Then, you want to take the wheel knuckle and pull it off the stud on the lower ball joints. Just remove that nut the rest of the way. Put it back on there and then just pull the wheel knuckle down and off that stud while pulling your axle out at the same time. It can be a little difficult, but it will eventually go. It's a good idea to just keep it secured to the top of the upper control arm, so just put that nut back on halfway for now.

Using snap-ring pliers, remove the snap ring along the top of the ball joint. Once you get it about halfway, you can just use a flat blade screwdriver and pry it up the rest of the way. With the ball joint press, we've got a cup around the lower part of the ball joint and that there, with a hole through there, so just press the ball joint right down through. I'm just tightening the press and then I hit it with a hammer at the same time, and that just kind of helps to break the ball joint free.

On the left is the old ball joint; on the right is the new one from 1A Auto. They do look similar, but there's some slight differences. However, ours will fit exactly the same. Remove the nut from your new ball joint and then you want to just carefully pry this boot off. Then set up your ball joint press and push the ball joint back into place. Again here, I'm going to tighten it up and just use the hammer to shock it a little bit to help it work its way in.

Once it's all the way back in, just replace that boot and make sure it's on all the way. Take your snap ring and put the snap ring along the top and make sure it's all the way down. Now take your wheel knuckle and you can remove the nut at the top holding it to the upper control arm. Then you want to feed your axle through while putting it back on that stud for your ball joint. This can take some maneuvering, but it will go, and then when you get enough space in the lower ball joint, you want to just replace that nut so it will hold it in place there.

Now push your upper control arm back into the wheel knuckle and replace that nut. Take your outer tie rod and push it back down and into the wheel knuckle and replace that nut. Then you want to torque that to 50 foot-pounds.

Push your new Cotter pin through, or your old one if you managed to save it, then just bend the tabs in opposite directions. Torque the upper ball joint nut to 50 to 55 foot-pounds.

Now replace the axle nut. Tighten it preliminarily. Put a jack underneath your steering knuckle and this basically raises the knuckle onto the ball joint to hold the ball joint in place. You want to tighten that nut up to 70 to 75 foot-pounds, and then further if you need to, to get the Cotter pin through.

Now, you can lower the wheel knuckle and then twist in your grease fitting at the top of the ball joint. We actually end up putting in a 90-degree grease fitting so it's a little easier to grease, and just tighten it up with our 7mm wrench. Then, just top the ball joint off with some grease.

Now you want to replace your sway bar link and you could see that ours was badly destroyed, so we're going to use a new one. You just slide it up through and the order is washer, then bushing, then the lower control arm, then bushing, then washer, then that metal tube, and then another washer and another bushing. Then it should be the sway bar, but you can see that the sway bar is just a little bit too low, so if you jack up the other wheel, you can see the sway bar go up and now you can fit in that bushing. Push the sway bar link up through the sway bar and then do another bushing, then a washer and then the nut. Then just lower the other side and it will compress the sway bar link and then just tighten that up with your 15mm wrench and 15mm socket and ratchet. For your final tightening of the stabilizer link, you can see I've got the vehicle on the ground, and the jack's underneath holding the suspension up in its usual ride height, and then I want to tighten it up so that the bushings basically come out to the same spot as the washers, basically compress the bushings down.

We'll fast-forward as Mike replaces the wheel and then replaces those lug nuts and just tightens them up preliminarily. Then lower the vehicle and torque each of the lug nuts to 100 foot-pounds in a crossing pattern. Then torque this 30mm nut to 184 foot-pounds, and then just replace your hub cap.
