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 .
