For perfect traction, use Red Line 75W90NS and add the Red Line Limited-Slip Differential Friction-Modifier / Break-In Additive until the chatter disappears."

Yes, Allan - I think that statement is correct. In order to get rid of the chattter - you want to add some slip to the diff's clutch plates. But not too much.

You can buy these Friction Modifier additives separately. They come in a very small quanity: like 25 or 50ml - to add to 1L or diff oil. LiquMoly makes one...
