I have the exact same noise. Couldn't tell if it was coming from trans or diff, but it drives me nuts. Mine doesn't do it all the time though. Going to throw it on the lift tomorrow and check out the diff. For a minute there I thought it was normal till I test drove another m at the dealer and it did not do it. Then I got scared. By the way mine is an 08 with 30k on the clock.

Edit: Just had car on lift and it is definitely not my differential bolts. They are intact and tight as can be. Did not have time to pull exhaust and heat shields to investigate further. Maybe next week.
