Customer Question

I drive a 2011 Buick Enclave. I just recently noticed what seems like a light knocking noise coming from what I think is towards the back of vehicle when I begin to accelerate from a complete stop. Once the car is moving at a good pace there is no noise.

Hello, my name is Bobby. Can you tell me if this noise happens every time you drive it?
Customer: replied 2 years ago.
Pretty much. It is a constant noise and it seems to be worse in thei morning .
Expert:  FIXITMAN replied 2 years ago.
Thank you. If the noise only happens a little when first accelerating then it may be a loose hanger on the exhaust, but if the vehicle is all wheel drive then it may be excessive free play in the rear differential. This is a common issue. Is the vehicle all wheel drive?
