Control Arms for GMC Envoy
I installed the control arms on my 2004 GMC Envoy last weekend. I found that the 1A Auto video was very helpful for the passenger side. However, the video did not mention that the trucks body poses a significant challenge for removing the left bolt on the drivers side control arm. I read online that other driveway mechanics had been faced with the same problem. I dont intend to report how I addressed the problem, since I dont want to encourage others to use my very imperfect solution. It would help if 1A Auto updated its video to address this problem.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Are the control arm bushings press on?
Matthew P October 12, 2017
I believe so, had a mechanic install them so Im not 100%. I can tell you that had to replace both after just over a year.
Robert H October 12, 2017
Yes they are.
Lawrence T October 12, 2017
Yes, they are pressed on from our vendors.
Alex P October 12, 2017
Yes they are, just make sure you remove the rubber housing before you insert them into press
Juaq G October 13, 2017
Yes. To remove lower strut mount, loosen nut holding strut to control arm until threads are even with outer edge of nut. Use prybar on lower strut mount to pry off strut while hitting the nut with a hammer. I found this technique on YouTube.
Terry K October 13, 2017
Yes..
Leon D October 17, 2017
