Re: Fluid Advice - 98 GC Diffs
It will make them chatter and grab on turns. I don't know about wearing
out. Most (sane) people can't stand the chatter and will get it fixed
before it does any damage. I installed an Auburn limited slip once, and put
some aftermarket "limited slip differential gear lubricant" in it. It
grabbed like crazy on the corners. That is when I decided that there is no
replacement for the OEM "friction modifier", whatever it has in it.

Re: Fluid Advice - 98 GC Diffs

Thanks again.
