This is something that just started but now that it has, it wears the tire quickly. I don't have any noticible sway when driving like my Jeep had when wearing rear tires (that turned out to be control bars). I don't think it's wheel bearings because I didn't feel any obvious movement but then again, I didn't force open the brake calipers either. Wondering if its some kind of control arm bushing, ball joints (does it have them in rear?) or something. Never seen a rear end like this personally. Anyone got an idea? This can't be just an alignment.
