Hello:

My name is Michael and I bought an '06 mustang last year. Shortly after I got it, I noticed that when I drive it between 20-40 Km/hr the rear end seems to shake left/right. Its almost like I have a warped rim or tire or the balance is off? I took it back to the dealer where I orginally purchased it and they noticed it too. They took out another '06 and they claim that it does the same and concluded that they are all like that. However I took it to another dealer for a second opinion and they could not find anything. It seems to be worse when it is cold outside. Has anyone else experienced this? I have the automatic trans in it.

Michael
