NHTSA Complaint #11076611 — 2005 FORD F SUPER DUTY

AFTER DRIVING OVER ROAD IMPERFECTIONS (E.G. BUMPS, POT HOLES, DIPS, ETC.) AT SPEEDS ABOUT 40MPH OR ABOVE, THE FRONT OF THE TRUCK SHAKES VERY VIOLENTLY, AND THE STEERING WHEEL MOVES QUICKLY AND STRONGLY, ALTERNATING RAPIDLY BETWEEN CLOCKWISE AND COUNTER-CLOCKWISE MOVEMENTS. IT IS DIFFICULT TO MAINTAIN CONTROL OF THE TRUCK; CONTROL CAN ONLY BE REGAINED AFTER SLOWING THE VEHICLE TO BELOW ABOUT 35 MILES PER HOUR, WHICH IS WELL BELOW ACCEPTABLE SPEEDS ON AN EXPRESSWAY. THIS IS NOT A ONE-TIME INCIDENT, BUT HAPPENS ALMOST EVERY TIME A ROAD IMPERFECTION IS DRIVEN OVER. TIRE PRESSURE IS CONSTANTLY CHECKED AND MAINTAINED, THE TIRES ARE RELATIVELY NEW (I.E. LESS THAN 10,000 MILES), AND THE STEERING AND SUSPENSION EQUIPMENT HAS BEEN CHECKED BY A MECHANIC WITH NO OBVIOUS PROBLEMS.
