I have a 2008 GT500KR with rear end noise. Sounds like rusty metal when turning slow. Like when you pull in a driveway. I have been told by the dealer that is normal. I don't buy that. Some one must know what to do here. The Dealer told me to drive 5 times in a figure eight and that should eliminate the sound for a short time. Is Ford crazy or what?! It's hard to believe this is exceptable by Ford to make cars that sound horrible. I hope some body out there has an answer. My car only has 200 miles on it. BTW, except the noise, very fun car to drive! CAD
Hi CAD Some other people have experienced the same problem and they took the car into the dealership and they added friction modify to the rear end. Do a general search under "Rear End Noise" and you will find some information.
