I've only be able to get around 1-2 runs out of a new rear diff. Ive been building the diffs to kit specs with 2 shims either side of the gear with no sanding of the gears. I have also tried adding extra shim's however i didn't see any improvement.

The diff has mainly been stripping the main larger gear only 1 side at a time. I have however had one time where it was the back of the gear where the pin sits which stripped out.

Does anyone have any solutions to my problems or know of any other brand gears that will fit the the tcxx housing ? Any help would be much appreciated.
