My 91 M5 has developed a really annoying (and expensive) sounding metallic knocking that comes from the back end of the car. I am inclined to think it's the LSD unit going south because it stops when turning and starts when moving forward or coasting. Normally, were it a CV, they usually click when cornering.... The sound is a cross between a tick and a clunk and can sometimes be felt through the seat. I know for certain it is coming from the back side of the car.
Fluid has been changed regularly with the proper stuff, but it's got 210,000 miles on it.
Thoughts?
