NHTSA Complaint #10746780 — 2008 FORD F SUPER DUTY

WHILE TRAVELLING ON A STRAIGHT, SLIGHTLY DOWNHILL, DRY SECTION OF HIGHWAY AT A SPEED OF APPROXIMATELY 40 MILES PER HOUR, AN EXAGGERATED SHAKING BEGAN ON THE PASSENGER SIDE FRONT TIRE OF THE VEHICLE. THIS QUICKLY BECAME AN ALMOST UNCONTROLLABLE BOUNCING OF THE TRUCK. IT BECAME INCREASINGLY VIOLENT IN JUMPING TO THE POINT IT MADE IT DIFFICULT TO CONTROL THE VEHICLE. I BRAKED AND SLOWED TO UNDER 20 MPH WHEN IT STOPPED. PULLED OVER, CHECKED ALL, NOTHING OUT OF SORTS. NO SIGN OF MECHANICAL FAILURE OR TIRE TROUBLE. FELT LIKE FLAT TIRE AT FIRST.
