I don't recall bottoming out but at some point in the past three years I possibly could have but don't remember. Do you have another theory? I would be surprised too if it was a bearing. I did read at another BMW list about an M5 that was making noise in the rear and the service department ended up putting a different type of fluid in the differential. It really has me baffled because when I drove the 2007 I really felt like I was in a luxury car. In mine it sounds like there is a hole in the floor letting road noise into the cab. Sure hope the dealership can sort this out.

If it is drive train I'm still covered by the warranty. Thanks for listening.
