How To Replace Rear Shock Absorbers 2002-09 Chevy Trailblazer
Created on:
Tools used
Socket Extensions
18mm Wrench
Jack Stands
18mm Socket
Ratchet
Floor Jack
1/2 Inch Breaker Bar
1. Remove the shock absorber
It is recommended to raise and secure the vehicle, but it is possible to do this with the vehicle on the ground.
Remove the 18 mm bolts at each of the strut by securing one end of the bolt with the wrench and use the socket and ratchet to remove the bolt from the nut.
2. install the new shock
Insert the shock into its mount and thread the bolt though.
Repeat with the bottom end of the strut.
Tighten the nut and bolts with your socket and ratchet and wrench
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.
We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll free, 888-844-3393. We're the company that's here for you on the Internet and in person.

Bought rear shocks to install at same time I put in rear Airsprings on my Rainier. Wow, another easy and painless job because of the parts, videos and support from 1Aauto. Thanks again.
Just so you know... back when I was still able to work, we had a saying in the building industry.....Price, Quality or Service - Pick two. I can tell you with 1Aauto, you will get all 3 without question every time!!!
Thanks to everyone at 1Aauto. With your help, your keeping my Buick on the road and my middle schooler in class.

I bought these for my son's 04 envoy to replace the stick ones. They work well. He said they ride good. They were nice made especially considering what they cost.
Seem to be good.

I watched the video for replacement of these shocks. Ordered them, and they came in 2 days. I replaced them in half an hour because I watched the video. They fit perfectly and work great. I have bought parts many times from 1aauto, and they have always fit perfectly and the prices and delivery are great.

Replaced a few components of my rear suspension. These shocks seemed to be a better quality than what I took off. I didnt know how bad my suspension was until I took the 30 minutes to install these. Will buy again if the time comes.

Put these and new springs on my 2005 envoy in Sept 2019, and they felt great and improved the ride significantly, but after 8000 miles they are covered in oil and getting soft. If you plan on keeping the vehicle, opt for a better replacement.
Great product

I purchased the full 4 piece set, fronts and rear. Installed rear. Then front after a few months. With less then 40k miles, one rear strut starting leaking. So time to change again.
I highly recommend 1AAUTO
