Help! I bought a used F150 at Carmax -- ever since I bought it, it will occaisionally make a grinding noise when I try to start it (sounds like when you start a vehicle that's already running). The noise is loud and abrasive. They replaced the starter -- that didn't fix it. Of course, they can't duplicate the problem when it's on- site. A co-worker said it may be the ring gear. Does anyone have any suggestions? The Carmax guys can't figure it out -- I've taken it there three times -- it there, again.
