The noise is hard to describe, but like a low rubbing sound, on both left and right hard turns. You can really hear it in a parking garage with the window down.
Update: Dealer replaced the diff fluid today with the one in quixs1lver's post. From the invoice:
"0053267 repl diff oil with special oil
3 83-22-2-282-583 final-drive gear oil (N/C)
Verified customer complaint per SIB 33 01 02. Replaced diff fluid and performed break in treatment. See attached bulletin. Break in procedure may take up to 600 miles."
I drove around my club's parking garage with tight corners and so far no noise.
6/30 update - noise is definitely gone
