makes noise, would'nt BeaZ notice it himself? Mine made a whooshhh sound in the early stages, then 2 months later went to whinning sound then couple miles later grinding. all my gear oil poured out on the freeway smelled like rotten eggs and was smoking a bit, whatever was left of the gear oil was dripping out on the side of the road after I pulled over.
I burnt my pinion bearing driving on the freeway somehow and ended up frying the oil seal as well. But oh well i gotta another diff from someone local for $260.
