NHTSA Complaint #10273332 — 2005 FORD F-350 SD

2005 FORD F350 4X4 P/UP TRUCK VIOLENTLY SHAKES. STARTS OUT AFTER HITTING SMALL BUMP OR BUMPS AND BUILDS INTO VIOLENT SHAKING FROM ONE END OF THE TRUCK TO THE OTHER. ONLY WAY TO STOP IT IS TO COME TO IMMEDIATE COMPLETE STOP. VERY SCARY ON THE FREEWAY. SHAKING STRONG ENOUGH THAT ANYTHING ON DASHBOARD OR CONSOLE IS THROWN TO FLOOR, STEERING WHEEL IS ALMOST PULLED FROM HANDS IF YOU DON'T GRAB ON TIGHT. HAPPENS IRREGULARLY AND WITHOUT NOTICE. FORD HAD BEEN UNWILLING TO FIX, SAYS THAT I CHANGED PARTS TO AFTER MARKET AND WILL NOT LOOK AT IT. I TOLD THEM PROBLEM STARTED BEFORE PARTS CHANGE AND THAT PARTS CHANGE WAS IN ATTEMPT TO FIX. THAT WAS OVER A YEAR AGO.. NOW I FIND OUT IT HAS BEEN HAPPENING WITH MANY SIMILAR VEHICLES, RECEIVED A LETTER FROM FORD AND NOW THEY ARE WILLING TO TAKE A LOOK.. I CHANGED SHOCKS, RADIUS ARMS, SPRINGS, HAD ALIGNMENT, NO CHANGE. SLIGHT RELIEF WHEN I CHANGED TIRES (SAME SPEC AS MANUFACTURERS), BUT AFTER 8-12 MONTHS WEAR, 8000 MILES, SHAKING BACK AGAIN. STARTED SHAKING AT APPROX. 12,000 MILES. TRUCK NOW HAS 32,000 MILES. *TR
