Brought to you by 1AAuto.com. Your source for quality replacement parts and the best service on the Internet. In this video we're going to show you how to change the front axle shift actuator on this 2004 Trailblazer. Same as any '02-'09 Trailblazer. Also the same as the GMC Envoy, Buick Ranier, Olds Bravada, Isuzu Ascender, and Saab--the 9X. Only tool you'll need are an 8-mm socket with a ratchet and extension. In this video I do have the vehicle up on a lift, but you really don't need to have anything like that. You can reach it right on the ground.
I'm looking at the passenger side front wheel. I have it turned all the way. We can see right in here, there is our axle actuator. An 8-mm socket with an extension and a ratchet. I'm just going to fast-forward through removing those two 8-mm bolts. You take your actuator out. Your lead, press on the tab right here, it comes apart. Blow out that a little bit. New actuator's on the right. All the same. They plug in the same and everything. Plug it in. Guide it through here to the hole. It's got an O-ring, just press it in a little bit. Set the upper bolt first. The lower bolt, I'm going to put into my extension and guide it in there.
Make sure they go in nice and easy by hand first, so you don't cross thread them. I'm going to use fast-forward again as I tighten these up. You don't want to tighten just one up all at once. You want to snug one and then snug the other one and then tighten them up after that. When you tighten them, you want to give them... they probably should be about 8 to 10 foot-pounds, which is not very tight. Just tighten with the small ratchet and that's about it. Don't over-tighten them. We hope this helps you out.

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 axle shift actuator on this 2003 GMC Envoy XL. The items you need are a new axle shift actuator from 1AAuto.com, an 8mm and 19 mm socket and ratchet with an extension . and a swivel is recommended ., flat blade screw driver, torque wrench, and jack and jack stands.
Start out by removing your wheel and tire. Pry off the cap first. If you don't have the benefit of air tools, you'll want to loosen the lug nuts then raise and secure the vehicle on jack stands and remove the lug nuts the rest of the way. We have air tools, so we put the vehicle up on jack and jack stands, remove the lug nuts, and remove the wheel and tire.
On the harness, on your shift actuator, just pry this clip down and pull it off. Now you want to pry out on the tab on the harness while prying down with another screwdriver to get the harness free. It can be a little difficult because sand does get inside there. You could get in here with something even as simple as an 8mm wrench. There are two bolts: one on top that holds it and then one on bottom. The easiest way is to use a nice long extension, and a swivel joint. I've got some tape on it to keep it stiff, and an 8mm socket. Just undo these bolts, and they'll come out. Once you get the bolts out, you may have to just tap on it a little bit with a hammer just to loosen it up, and then it will come out. Once those two bolts are removed, the actuator just pulls free.
On the right, is the old axle shift actuator. On the left, is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Take your new axle shift actuator and push it into place. Then replace those two 8mm bolts by hand. Then tighten them up the rest of the way with your ratchet and extension. Reconnect the harness and push that clip back up into place.
Replace your wheel. Replace the lug nuts and tighten them up preliminarily. Lower the vehicle. Tighten them the rest of the way and torque each of them to 100 foot pounds in a crossing pattern.
