Re: Rattle noise from T-case?
I do have brand new U-joints and while I was in replacing those I did do a good inspection of the slip yoke and the short stub coming out of the T-case as well. All looked good, slip yoke was greased and high quality Ujoints were installed. The noise was there before and after the u-joint replacement. My bad U-joint made its own special racket.
I will say that the rattle is more like what is being described from others, as a vibration like sounds, so what Im hearing is most likely what everyone else has said as well.
