Yeah.. I hear ya. Mine doesn't make any noise at any other time, however... even when turning. Only at higher RPM under load.

I would guess that you are right with the thought of it being the diff housing rolling upward... Maybe it's hitting the pinion nose snubber or bumpstops.. and tranfering noise/vibration into the cabin through the floor.
