I own a Ford Super Duty F 250 2006 was bought 03-18-10.aprox 2 1/2 months the truck violently shakes and loses control when hitting the smallest bump if exceeding 45 klm our higher. If you apply your brakes while this happens the back end will 360 this is a death trap. This has happened about 15 times but it could of been more I only drive very slow and in the slow lane so if it happens I can pull over. I have had everything repaired on this truck I replaced all the heavy duty shocks the tie rods the steering damper the alignment the pressure in my tires and even the brakes, at first I thought the garage just wanted my money but once searching on the internet I found many others with the exact same problems no one has found a solution to the problems and my own mechanic says he has exhausted all avenues with this truck. My biggest fear is someone will have to die to make Ford understand there is a defect with this truck and I don't want it to be me. I have not driven this truck in the winter as of yet and can tell you with experience if the truck shakes violently and I have a had a tough time controlling it in the summer imagine the winter. Someone needs to take this serious. Just tell me how to fix it at least I can make it safe.
