Q: Noise at rear of vehicle

asked by on

I hear noises at the rear of the vehicle.

A: A noise in the rear of the vehicle could be...

A noise in the rear of the vehicle could be three things: the rear end bearings or gears are bad; your wheel bearing is bad; or your U -joint is failing. If your rear end is going bad you will notice a grinding sound that will have a significant difference in sound when you put it under more stress by accelerating faster. If your u joint is failing then you will more than likely hear a knocking sound that will get louder the more load you put on it. A wheel bearing will make a grinding sound but will stay steady regardless how fast you accelerate. I would recommend having a technician for YourMechanic come out and inspect the sound and determine what needs to be fixed.
