NHTSA Complaint #10256667 — 2006 FORD F-350

I OWN A 4WD F350 DUALLY. WHILE TRAVELING AT HIGHWAY SPEEDS APPROX. 45MPH AND ABOVE AND AFTER TRAVELING OVER AN UNEVEN ROAD SURFACE OR BUMP IN THE ROAD, THE FRONT END GOES INTO AN UNCONTROLLABLE SHIMMY/OSCILLATION. THIS CAN ONLY BE STOPPED BY PULLING OVER AND COMPLETELY STOPPING THE VEHICLE. I HAVE TAKEN THE TRUCK TO A FORD DEALERSHIP WHO CHECKED THE FRONT END AND SAID THERE WAS NOTHING WRONG W/ THE TRUCK AND THAT IT WAS A TIRE PROBLEM. I HAVE SINCE THEN BOUGHT NEW TIRES WHICH SOMEWHAT LESSENED THE PROBLEM BUT DID NOT CORRECT IT. I ALSO HAVE TAKEN THE TRUCK TO A REPUTABLE INDEPENDENT ALIGNMENT SHOP, AND THEY TOLD ME THAT THEY HAVE SEEN A LOT OF TRUCKS W/ THE SAME PROBLEM, BUT ARE UNABLE TO FIX IT DUE TO THE DESIGN OF THE FRONT END. THE INDEPENDENT SHOP SAID THERE IS TO MUCH CASTOR IN THE FRONT END AND NO WAY TO ADJUST IT. I AM NOW ON MY THIRD SET OF TIRES W/ ONLY 45000 MILES ON THE TRUCK. I BOUGHT THIS TRUCK FOR AROUND $ 48,000.00 AND HAVE HAD THIS PROBLEM SINCE THE TRUCK HAD ABOUT 23000 MILES ON IT. I CANT EVEN DRIVE IT ON THE INTERSTATE DUE TO THE UNCONTROLLABLE FRONT END SHIMMY. THE FORD DEALERSHIP WILL NOT ACKNOWLEDGE THAT I HAVE A PROBLEM. I HAVE SEARCHED THE INTERNET AND HAVE FOUND POST AFTER POST OF PEOPLE WHO HAVE THE SAME PROBLEM WITH THEIR TRUCK AND THE LACK OF ACKNOWLEDGMENT FROM FORD. THIS IS A VERY SERIOUS PROBLEM AND TO DATE I HAVE SPENT OVER $ 1,600.00 TRYING TO REMEDY IT. I HOPE SOME ONE FROM YOUR DEPT. IS FAMILIAR W/ THIS AND COULD POSSIBLY HELP ME. THANK YOU STEPHEN HALL *TR
