So I decided to bring my 2005 Mustang GT in today for an inspection and it failed. They said my ball joints were bad. I am a bit surprised that the ball joints could have gone bad on a car that is not even 3 years old yet. I am guessing that they have checked them wrong, but since the car is under warranty still I scheduled an appointment with my ford dealership to check this out. Has anyone else had any problems with their ball joints?
