sure I saw a thred about this on here, some one asking about diff bits
Diff plates in the monkey seem a bit soft, once you have fitted good quality balls the plates seem to groove very soon after, I have started to use Associated drive rings part no 7666, direct fit onto outputs, diff is now super smooth

after a few runs
