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

It was making clunking ktank noise after slowing down and making a turn , and in parking lots . The inside drivers wheel would chatter and lock unlock on tight slow turns. That was with the Furd fluid the garage insisted was good for the diff , guess what car is allergic to the Furd fluid , now runs quiet , had one ktank just after changing fluid , nothing since .

So thank Abodie people , your suggestion seems to have done the trick .

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
