After having the 3.73's installed, my limited slip diff started squealing again during slow turns. What is the best differential oil and friction modifier known to mankind that will end this? Just want to make sure because changing this is not easy, and the stealership probably won't cover it since I had the gears changed.

What the heck is tufoil, and where do I get it? Use a full pint?

Go to the dealer & get a bottle of friction modifier<--- that is some slick stuff. Will take out 99% of all chatter & noise, and cost about $5-6

Tufoil is the best lubicant out there. You have to order it at Tufoil.com. You don't have to use a whole pint. I add it to my regular oil after a oil change. I think they have gear lubricant as well.
