Ok everyone I got one for you, my son had a friend of his, take his car down just to change the tires and do an alignment, when he got the car back it was making a funny noise in the back right, when he turns a corner, he said it makes a clunking kind of grinding noise. He took it to Brian (no shoes) and he took off the CV axle and checked that, (which was ok) then brian suggested the wheel bearing, (not it) my son drove it home from Brians moms house and he said he can't hear it at high speeds just lower speeds, I told him he needed to check the used tire he put on it, hasn't done that yet. Brian says he has never seen anything like it before. Has anyone ever come across this? or have any other suggestions?
