Bought the truck and it occasionally would make a grinding sound when I took sharp right turns...into a driveway for instance. So I replaced bearings and races and repacked with fresh grease, new rotors, pads, and calipers. After about a month of driving with no noise I heard it again yesterday. Still only on right hand turns. There are no rub marks of any kind and I am baffled...anyone else had this? Ideas on what else I could check?

Thanks!
