So I just installed some new Bilstein 5100's assembled by PRG Products, new lower control arms and eccentric bolts. They ride great! Only problem is, I have a creaking noise coming from the driver front side. Sounds kind of like something rubbing, I can duplicate it by bouncing the front end up and down. I tried spraying some WD-40 on the bushings, but cannot get it to go away. I was wondering if there may be something else I should check? Maybe I installed the Bilstein's wrong?
