I just replaced my passenger side with a Mevotech upper control arm. Most of it was straightforward except the pinch clamp that goes on the ball joint was too thick to seat all the way down and I could not get the pinch bolt back in without grinding material from the bottom of that section. Think I'll try another brand when I replace the driver's side. Also the ABS cable clamp would not come out of the old arm not matter how much I tried working screwdrivers etc. up into the clip. Finally broke and now I have it securely zip tied into place while I try to find a replacement.

Hey Chris Fix, I just wanted to thanks for this video. After watching this, I was able to replace both left and right upper control arms on my 06 Trailblazer. I started with the left side first since you mentioned that was the hardest side. You weren't kidding. lol
The right side didn't take long at all. Anyway, thanks again. Now I need to take it in for a wheel alignment.

Ratcheting wrench seems like a bad idea there - at least the kind that you have to flip to reverse. You put that on there and turn the bolt out, you get to the point you can't go any farther, you can't get the wrench off anymore, the bolt isn't out far enough yet, and you can't screw it back in again.

Nice Chris! Just bought one of these and was checking to see the process. First video on this part and bam its ChrisFix here.
Friendly tip for anyone with the cold start issues (clean throttle body) mine was gunked up after a serious clean the truck runs and start like a dream.

Chris, you are the man! Love how you
give excellent tips and procedures for all your tutorials. I've been using your expertise for many years. You've save me sooo much money, and I'm simply a novice. Keep up the great work. It's much appreciated.

IF YOUR JACK STAND IS UNDER THE LOWER CONTROL ARM AND THE WHEEL WAS LIFTED JUST OFF THE GROUND, (about an inch, at the most, WHEN YOU LIFTED THE VEHICLE. YOU DON'T NEED TO PUT THE WHEEL BACK ON WHEN YOU TORQUE THE UPPER CONTROL ARM BUSHINGS. cheers!

Thanks ChrisFix, now I want to go outside and rebuild my entire front suspension. :)
She's a 2004 Chevy TB 4X4 with 200, 000 miles so it probably needs it done anyway.
It's a great vehicle for my needs.
Thanks for the awesome videos. :)

Because of you I believe I can do this myself.
I dont have a ball joint press but I am getting in from Amazon. It is 100 cheaper too!
Would it be ok to do my upper arms and later do the ball joints when the press arrives?

reply

Thanks for the lesson. I was planning on paying a mechanic to do this, but after watching your video, the only money I'm going to spend for a mechanic is for a wheel alignment after I install the new uppers on my 06 Trailblazer.

I've the same problem in my 2007 Trailblazer, thanks for the video, but you were not cut in the car's metal you were cutting my heart: ), there must be another way to do that get that screw out.
