Tm2 v1 ball diff issues

[Gavin Collingwood]

Right guys I'm having issues with my ball diff. The diff needs to be tightened very tight to stop it slipping (too tight really) and because of this the diff it's self is getting very hot! Which in turn drains it of any diff lube and goes very gritty.... Something isn't right....? I've put new balls and plates in it too but it makes no difference?.... Can anyone help? Really want to try the ball diff as the car does feels more smooth than with the gear diff
