At your next scheduled oil change. Tell the service manager to add Friction Modifier to your rear differential and it will go away.

Mine would whine after I ran the car hard and I would make a slow 90 degree turn. I had them put the friction modifier in and it doesnt do it anymore.
I went over to Dennis G's today and let him drive my 08. I asked him about that funny noise when turning at slow speeds and he said it was caused by the TC in the rear end. He turned the TC off and it seemed to get worse IMO. Is this normal for most of you out there. I guess I will get the Friction Modifier added to make this terrible noise go away?
