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 rear shock removal and replacement on this 2004 Trail Blazer, same as most of these mid-size SUVs. Tools you'll need are 18 mm socket with a ratchet and extension, and also an 18 mm wrench, and you probably would want jack and jack stands to raise and support the vehicle, but not totally necessary.
So to replace your rear shocks, as you can see I still have the tire on the truck, and you could actually do this on the ground, although it will cause a little clearance issue as you try and remove this lower bolt. But it's possible, you can do it on the ground. So there's that lower bolt, and there's a bolt up high right there. And if you are jacking your vehicle up, you can see my lift is under the frame. And then I have a bottle jack right here that's supporting the axle. You just want to give a little support of the axle so it doesn't drop down when you release the shock. What you probably want to do is take a couple extensions, that way you can work right outside your tire. And it'll come right apart, as you can see.
This is an 18mm again, and you might need two wrenches. One for here, and one to hold. But little trick... if all you have is wrenches, hook another wrench onto the end of that one, and that gives you some extra leverage. And like I said, on the ground this is going to be somewhat more difficult. Now I'm going to cheat 'cause I've got 18mm deep socket and an impact wrench. Comes right out. Back up top here. So that's how your shock comes out. Again, the shocks on this vehicle are fine. Just showing you how to do it. So to reinstall it, you want to put the top back up in. Put this top bolt in first. Now the bottom. Put that back in. Start that nut on. A good rule of thumb for these is get it about as tight as you can get it with a ratchet like that. And up to the top here. Again, just got my ratchet on here. That's tight as I can get it with the ratchet.

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 rear shocks on this 2003 GMC Envoy. It's the same procedure for all these SUVs: Envoy, trail blazer, Ascender, Ranier,. We show you the right side; the left side's the exact same procedure. Always replace your shocks in pairs, and you'll need new rear shocks from 1AAuto.com, 18mm socket and ratchet with an extension, and it helps to have a deep socket, an 18mm wrench. You can do this without even jacking up your vehicle, but for the video, to make it easier, we do put it up on a lift and use a jack.
Your rear shock is held in with an 18mm bolt up here and an 18mm bolt down here. Using an 18mm socket and ratchet, and 18mm wrench, just loosen up this lower bolt and hit it out as far as you can with the wrench. We'll fast forward as he loosens up the top bolt. You don't have to entirely remove them until you've loosened both of them. That makes it a little bit easier. If you are using jack and hack stands, have the jack stands supporting the frame of the vehicle, and then put some upward pressure on the rear axle with your jack to take some of the load off of the shock. I'm just watching the top of the shock to see it compress some. Now with the bolts loosened, you can pull the lower bolt out and then pull the top bolt out. You see that? Then it pulls free.
Up top, is the old shock. Below it, is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Feed your new shock up into place and replace that top bolt to hold it in place. Now, you'll need to line up the lower hole and this I only have to push up a little bit. If you have your vehicle on the ground you'll have to push it up more, push the shock up and then put the bolt through. We'll fast forward as Mike tightens those both up. Right now you're just tightening them preliminarily, although you can, if you're working without a jack and jack stands, and the vehicle's on the ground, you can tighten them up. What we do is we start up the vehicle just to give the air suspension a chance to inflate and make sure the vehicle's at its correct ride height. Then once we know it's at the correct ride height tighten up the bolts for the shocks.

No wear as of yet. Great solution to air suspension.
Fast shipping, Great fit. A1 Auto has been amazing!
I ordered this item and it came within no time. I have no issues with it other than at the last minute I realized it DID NOT COME WITH UPPER COIL SEATS. Which is a major problem when you are trying to covert. That should be stated in the description of the item. I had to run out and search for them. My suggestion, it should be included with the rest of the items
Easy installation, fit like a glove! Thanks for the awesome product
Looked around found their kit .all worked like it should .
the conversion kit fit perfect easy install thanks again.
