When a diff feels "gritty", then its time to replace it right?
Well what should I do when the diff is gritty right out of the box? And just what counts as being "gritty"?
I don't have much experience with ball diffs, and I don't know what the optimal tightness is, but, the only time it is buttery smooth (like a zero resistance bevel diff) is when it is too loose (can turn pulley with outdrives held still).
The tighter I make it, the more resistance when turning the outdrives (in opposing directions), the more gritty it feels.
No matter what tightness, it feels like there's a piece of sand paper in there with the balls. So what's the deal here? This was the way it felt brand new, and this is still how it feels after 4 packs and a re-put-together of the diff.
What is strange though is, if I try to push the diff together, that is pushing with the outdrives in towards the centre, the harder I push, the smoother it is. Yet tightening it makes it grittier.
