NHTSA Complaint #10849651 — 2012 FORD F-250 SD

THE VEHICLE HAS 34,000 HIGHWAY MILES ON IT. THIS ISSUE FIRST BEGAN ON I95 @ 29,000MI. WHEN HITTING A BUMP, SUCH AS BRIDGE EXPANSION JOINT, THE VEHICLE BEGINS TO SHAKE UNCONTROLLABLY. THE BRAKES DO NOT WORK PROPERLY WHEN THIS HAPPENS BECAUSE THE TIRES ARE BOUNCING OFF THE ROAD SURFACE CAUSING ABS ACTIVATION. THE SHAKING GETS WORSE UNTIL IT COMES ALMOST TO A STOP. VERY DANGEROUS ON THE HIGHWAY IN LANE 1 AT 75 MPH WITH CARS ALL AROUND. THE PROBLEM IS RELATED TO THE TRACK BAR. THIS PROBLEM IS UNSAFE AND WELL DOCUMENTED ON SITES SUCH AS YOUTUBE. THE TRACK BAR ISSUE DOES OCCUR ON SOLID AXEL 4X4 VEHICLES WITH HIGH MILEAGE (200,000) BUT NOT ON LOW MILEAGE TRUCKS LIKE MY F250. I HAVE REPLACED TRACK BAR BALL JOINT AND PROBLEM WAS FIXED BUT HAS NOW WORE OUR AGAIN CAUSING A RECURRENCE OF THE ISSUE. VERY DANGEROUS EFFECTING STEERING AND BRAKING. I CAN SEND VIDEO OF THIS OCCURRING IF NEEDED.
