So I recently did the rear camber mod and used 5 washers per bolt. I used class 10.9 bolts, hardened washers, and a lock washer on every nut. At the same time I did the camber mod, I also had to change my lower links and cam bolts as the parts were rusted out and toe angle could no longer be adjusted.

Since doing this mod, I have noticed strange noises coming from the rear end when taking turns (both right and left) as well as sometimes when I go over a bump. It sounds almost like a rubbing, or something sliding back and forth during the duration of a turn. Really weird. I checked all the bolts, both on the links and the upper mount, and everything is tight.

Anyone ever have this problem or have any idea what this could be?
