Excellent parts and Helpful Videos
Ive been working on my own vehicles for about 20 years, and 1aauto has the easiest to follow and most in depth videos Ive ever used. I believe Mike is his name who does the videos and he is great. The parts 1aauto offer are great quality and ship very quickly and Ive always found my part. The site is very intuitive in that when I bought my control arms, I would get helpful emails on deals for other suspension parts. I love this company and site.

Regarding changing the lower control arm with ball joint assembly. When you state "ride height", how do you determine this on the 2006 Trailblazer?
Thank you for contacting us. Can you please clarify your question?
