This is definately from the rear.
Only on accelleration in drive. More rapid and louder earlier under accel. and diminishes as it gets up to speed and I back off the throttle.
Does not happen when parked and revving engine.
I was able to reproduce it slightly by standing on the brake and revving the engine while in drive. I had a friend outside the car confirm that it was from the rear drivers side.
