Yeah I was taking the bronco home this weekend. its first long trip and i burned up the rear end. I smoked the wheel bearings. I pulled the shaft out and no oil came running out. But i filled it full to the plug. so i put new bearings in and got the truck at a angle so i could put more oil in the diff. I think the angle of the rear end caused the oil level to be too low. has anyone else had this problem.
