Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

A thumping noise is quite hard to try to diagnose if I do not have the feel for the vehicle. I do know there is suspension components back there, for some reason I feel it can be the differential bushing causing this issue since I have experienced a similar issue you are experiencing.
