I wonder if it is the limited slip plates not slipping? Do you have the additive in it? I did put more in then what they say to on an 80. Still works well in mud.

is it vibrating when turning and backing? limited-slip shouldn't be a factor in a straight line. my experience has been pinion angle change causing the most vibration. under moderate acceleration towing heavy I get some vibration, even with a driveshaft with CV joint. maybe worn u-joint.
