wheel bearing? a friend of mine had this issue... well somewhat... it was making this rubbing sound like a boot was broken turned out to be a wheel bearing... no clicking or anything...

did you use oem axles? some aftermarket come pre fucked up i've been hearing... trying replacing it again...

to check ball joints check if they are freakishly loose...

doubt shock will do that...

and the tranny if it's busted drain the fluid and check for metal flakes?
wouldn't the wheels spin (when turned manually) together if the diff is blown?
