Rear wheels not turning
I ran my 8T today she was doing fine running like a banshee. I noticed my rear wheels were not spinning. Front was doing all the work. Thought no biggie grub screw cam loose, Not. So I figured it was the diff took out one and popped in a new one. Still the rear wheels don't turn. What I mean by that is. If I turn the fronts the center diff turns and the rear wheels turn. However if I turn the rear it does not even make the center diff turn. Not even the axle is turning. Any Ideas?
