I went to the dealer ship today with a roaring noise in the rear end. A TSB has been filled out on 2004 and 2005 mustangs and other vehichles. one of the symptoms was a vibration, whining, roaring sound and others were listed. I am not sure if this helps or not, but, my problem is (excuse the spelling) Rack and Pins and shift differental was ordered today.
