This just started today. When I put the car in reverse and back up I can feel and hear a clunk coming from the rear end. It does not do this when moving forward. The rate at which it clunks is proportional to how fast I back up and I seem to feel a consistent number of clunks per wheel revolution, not irregular. What could have happened?

First be sure to check that the trans mount or torqe arm mount is not broken if not next step is to check the u joints and if its non of those check the back lash on the rear end

I had the same problem one time and it was a cracked carrier mine cracked between the cross pin, It was rubbing the pinion gear.Not saying thats what wrong with yours, but just a idea. Have you done any hard launches or hard shifts.
