Upper Control Arm Mounting Problems
Posted: Fri Sep 23, 2016 8:56 am
Since swapping to the new tubular upper control arms, I noticed that my car feels very stiff. I thought it was just a Gen3 thing until I unbolted the two sides of each control arm and tried to rotate them by hand. They all require tremendous force to rotate around the pivot and I have been told that they should rotate easily with just pushing them with 1 finger. I tried grinding down each end of the brass bushings so that the pivot tube would stick out a bit further. This definitely helped, but it still takes a good amount of force to rotate the arm back and forth. My only thought now is that the pivot tubes are too tight inside the brass bushings. Am I on the right track or am I going too far? I have a few questions.
1. How easy should the upper control arms pivot?
2. How tight should the pivot bolt be? I tighten them until the mounting shim in the picture stops rotating with the control arm. Is that the correct way?
I appreciate any help. Thanks.
