I installed new control arms and after noticed that the left had a big R on it, assuming this means right side, I installed them at different times meaning 1 day after the other. I think auto zone sold me wrong sides and i put them on like a ********.....anyway my point is that I also put new wheel bearings in 95 spindles for brake upgrade and now something is loose in both wheels. Am I going to have to replace bearings and is there a huge difference between left right control arms that I have to switch them?!?
