Re: 80 mph rear end noise and the dealer
I just bought a certified '04 coupe a couple of months ago. I was hearing a whining sound from about 40 mph on up when it was under load. Take the foot off the gas and it would go away. It's now being fixed on warranty. The new differential will be in early next week. The posts on this forum helped me to identify the problem and get it taken care of without any BS.
