Just got back from the Dealership.
Went for a spin with the Shop Foreman....he said whatever it is , it is not good.
I still think it's the front ring gear, he opened the door while we were moving, and MAN was it loud. Could be the rear ring gear or the T-case.
I'll side with f5 that it's not likely the t-case.
I'll know more later today!
