It could be that "sheet metal rear panel" shifting making a sound that some folks experience ...??
It could be that the differential is just cold ... ??
Maybe the rear axle universals are worn ... ??
If it continues, you may wish to take it into a shop for a look see.....

Don't think it could be abs or emergency brake because the sound happens after I have backed up out of my parking space or garage and start moving forward.
The sound happened again once on my way home from work yesterday as I pulled out of my parking garage after coming down 3 floors with no sound.
It most definitely is coming from underneath the car and I can not only hear it but feel it as well.
Right now its not something that I can easily repeat because after driving for 5 minutes and the car is warm it does not happen. If I park the car and get back in a drive it before the car gets completely cold it does not happen.
I want to take it to the dealer for a look see but I am thinking I need to wait until it happens more often otherwise I will be wasting my time when they claim they cannot find anything wrong.
