I too have the high pitched whine from the rear end. I suspect it too is a rear end bearing as it is something obviously spinning very fast, and it seems to go away when side loaded (during cornering). Also just started getting a mild gear oil smell in the cockpit suggesting something getting hot. It also takes longer to happen as the ambient air temp goes down. Only occurs after driving about 20 minutes. Has anyone tried a different rear end lube (after possible bearing replacement)?
