Diff whining when making tight turns
When I make sharp turns at very slow speeds (1-7 mph), I hear a whining/grinding noise from the rear diff of my '99 FRC. The previous owner of my car said he put Redline differential fluid in there. I'm assuming it requires either the GM diff additive or friction modifier?
I remember reading something about this in the FAQs, but I can't seem to find that thread.
