I just got a 06 LT with 18k miles... ive got a loud pop when hitting pot holes, so im assuming its either the stuts, LCA's, or sway bar bushings.

so far ive purchased the fe5-s strut/shock combo on ced... ive also purchased some ss/tc springs... next im looking at sway bar end links, and control arms. I dont know why the FE5 LCA's are an upgrade, but ive read that the bushings are crap, so im leaning toward the moogs, but they dont have an fe5 setup. Can some of you guys with first hand experience chime in on your opinions on which lca's to buy and why?
