| I heard a slight grinding noise, that sounded like a brake dragging. i replaced brakes all the way around, and that didn't stop the noise. i then replaced all the wheel bearings, this did not help either. i tried the u-joints with no luck. i was talking to the person that i got the vehicle from and was told that the rear end had been rebuilt twice! this was before i got the vehicle, and it only had 67000 on it when i got it. since then i have talked to many yukon owners, and they have had the same issues. | |||
