NHTSA Complaint #10498268 — 2006 FORD F-350 SD

I OWN A 2006 FORD F-350 KING RANCH CREW CAB FOUR WHEEL DRIVE TRUCK. I AM THE ORIGINAL OWNER. A FEW TIMES THROUGH OUT THE YEARS THERE HAD BEEN A SHAKE AFTER HITTING A BUMP IN THE ROAD AT 60MPH+. WE RECEIVED A LETTER NOTING A POTENTIAL PROBLEM. WE BROUGHT THE TRUCK TO THE DEALER AND THEY REPLACED BRAKES AND 2 TIRES (OTHER 2 HAD BEEN REPLACED PREVIOUSLY) AND WHEN WE DROVE IT HOME IT STARTED "THE DEATH WOBBLE" (AS THE DEALER CALLS IT-AND AS I SEE MANY OTHERS ON THE INTERNET). THE TRUCK STARTED EXPERIENCING VIOLENT FRONT-END SHAKING. DURING AN EPISODE OF LEFT-TO-RIGHT SHAKING, THE TRUCK IS VERY DIFFICULT TO CONTROL. WITH MY HAND PLACED ON THE 12:00 POSITION ON THE STEERING WHEEL, THE SHAKING VIOLENTLY TURNS THE STEERING WHEEL TO WHERE MY HAND IS GOING BACK AND FORTH BETWEEN 10:00 AND 2:00. SLOWING DOWN TO 30MPH HAS STOPPED EACH OF THE THREE EPISODES. THIS TRUCK HAS DEALER INSTALLED TIRES AND DOES NOT HAVE A LIFT KIT ON IT. AIR PRESSURE IN THE TIRES EQUAL MANUFACTURERS RECOMMENDATION. THEY ACTED AS IF THIS IS AN UNCOMMON PROBLEM AT FIRST, AND SAID THEY HAVE NEVER HEARD OF A LETTER THAT WENT OUT. THEN THE NEXT VISIT THEY SAY SO COMMONLY, THAT IT IS THE DEATH WOBBLE AND WILL COST $1500. IT APPEARS THAT FORD MOTOR COMPANY HAS BLAMED TIRE PRESSURE, GIANT AFTERMARKET TIRES, AND LIFT KITS FOR THIS PROBLEM. MY TRUCK HAS NONE OF THESE POSSIBLE CAUSES. *TR
