Abig thanks to the people that suggested I use mopar sure grip fluid in my 8 3/4

So now you have gone from a tight LSD to a loose slipping one?
No it's not slipping , still tight , but before it was like the clutches were binding and letting go with a big k-tank . Puts 2 nice strips down the road and inside wheel skids on gravel in a tight turn , no more big "unbinding" k-tank noise .
Or is that a normal noise on an LSD diff ? No one liked that noise at the shop , was not normal
