Hotshot gearing

[smegs]

Hi guys I have a question. Does anyone have a prolbem with the rear gear case. I spin the rear diff and it somrtimes binds and turns rough. Then it goes smooth again. Any suggestions. I have the old original release. And Im rebuilding it completely.

The metalpot differential gears maybe are worn out.

It could be that the centre pin that goes through the 2 drive cups is slightly bent, you could try the one out of the front instead. Could of course be grit in the grease.
