Well I never thought this would happen but my 8th scale center diff failed. The diff cup broke. I think it is my fault because I turned down the cup a little bit for more clearance which I'm sure weakened it. So I replaced it with a new unmodified cup and I went to extremes and put 100k in the diff and will see how I like it.
This is what I did to the cup before. The stock cup on the right and the modified on the left. Not a good idea as the whole center part of the diff cup broke off.
