*Update*
Ok, finally got a chance to work on the car for a few and think I've figured out what this noise is.
About this time last year I bought a set of replacement control arms from autopartswharehouse.com I had a feeling these would not be of the highest quality........
Turns out I was right, the big bushing that rides in the mount towards the back of the car turns out to be......... a metal ribbed skeleton with a rubber coating on the outside of it, the rubber had somehow gotten torn or rubbed away??
Greased the hell out of that spot, re-assembled, drove, no noise!
So now, I"m going to rebuild my OG control arms with new ball joints and either stock bushings or the ES set. Ive seen some Whiteline bushings for that location but have not seen any feedback on them.
Opinions?? on the ES set too if you have them??
