i'm trying to figure out whats making the clicking/grinding noise on the front of my truck...its doin it on both sides too. my truck has about 212,000 on it and it looks like the front hubs could be the originals. could these be making noise or are hubs usually pretty quiet. i've never had a truck with hubs so i'm lost here. could it maybe be the wheel bearing or a universal. the thing is, i've had bad u-joints before that went click click click, but this is more of a grinding or rattling??:dunno:
