Yikes. That pinion gear has definitely seen better days.I've just stripped the backend down and took some photos.
Originally I thought that the gears looked in good condition when I had them out but checking the photos again now, possibly the input gear is looking a bit work, it's hard to tell since I didn't do a very good job of cleaning the grease off.
During the disassembly, I noticed that the diffs bearings were ****ed leading to the input gear having a bit of play.
Luckily I have plenty of spare bearings kicking around so replaced those removing all of the play.
I put it all back together (dismantling and cleaning a shock in the process) with the hope that this would now be sorted but nope, still there
Again I couldn't see any cracks or misalignment or anything obvious in the diff case but I think it's gotten to the point where I am just going to replace the lot like VaporTrail says: a new diff case, input gear, diff gear.

A fresh set should put a smile on your face again, although I'd take a closer look at the center and front gears just to be on the safe side.
