Can anyone help? Ive just bought a 2005 V6 Mustang manual, its a great car, but at bang on 71mph im getting a rummble which seems like its coming from the rear, as i increase the speed i can drive through it, but 71mph is a nice speed to cruise, the car was standing for a while before i bought it, i am thinking is it the propshaft?
Would be greatfull if anyone has any idears.
