There is an odd knock from the drivers side front when the suspension compresses. It's very random, but will happen every time I go over a speed bump. I was under there with a pry bar and everything is tight, both with wheels on the ground and supported by the frame with on weight on the wheels. It's kind of driving me crazy, any thoughts on what to check out? The smurf is lowered 1.5" with eibachs on Tokico shocks. UCA & LCA are newer MOOG, strut rod bushings are new, factory rubber to sub frame.
