Just very minor up and down movement that was making a lot of noise. I stuck a washer in there and tightend the bolt back up and it went away. I discovered it by letting a friend drive around a parking lot and I was sitting in the back of the Z with the hatch open, hanging over the rear looking at the suspension while we were moving lol.

hmm.. when i brought it to a lift.. me and my friend was trying to move everything to check if anything was loose including the diff.. but everything seems like its tight.. maybe ill check again in the spring time when i install my exhaust...

were u able to wiggle your diff by hand?
