Rear Diff?

[SupraDupra]

Since these are LSD's they probably use clutch plates to lock up and the pads are worn.

And I don't mean to hijack this thread ,but it seemed a good place for my question as well.Occasionaly while accelerating through a wide turn my rear end shudders pretty hard.I don't have much experience with closed differentials ,is this the LSD locking and slipping in the turn? If I realy throw it into a turn there is no problem ,seems to only happen while accelerating into a wide turn (such as across 5 lane intersections)
