NHTSA Complaint #11351340 — 2010 FORD F-350 SD

WHEN HITTING A ROUGH SPOT IN THE ROAD OR ESPECIALLY WHEN CROSSING A BRIDGE EXPANSION JOINT AT HIGHWAY SPEED, THE TRUCK DEVELOPS A TERRIFYING, VIOLENT SHAKING/VIBRATION AND THE ONLY WAY TO STOP IT IS TO SLOW DOWN TO 25 - 30MPH, WHICH IS VERY DANGEROUS WHEN DRIVING ON FREEWAYS SURROUNDED BY OTHER VEHICLES. MY WIFE REFUSES TO RIDE IN THE VEHICLE ON THE HIGHWAY AFTER EXPERIENCING THE "DEATH WOBBLE".. THE TRUCK HAS HAD VARIOUS STEERING AND SUSPENSION COMPONENTS REPLACED WITH HIGH QUALITY AFTERMARKET PARTS INCLUDING SHOCK ABSORBERS AND STEERING DAMPER WITH NO CHANGE IN WHAT HAS BEEN CALLED THE "DEATH WOBBLE". THIS IS AN INTERMITTENT PROBLEM AND DOES NOT HAPPEN EACH AND EVERY TIME WHEN HITTING A BUMP OR CROSSING A BRIDGE JOINT. MULTIPLE TECHNICIANS HAVE BEEN UNABLE TO DUPLICATE THE PROBLEM EVEN AT LOCATIONS WHERE IT HAPPENS FREQUENTLY.
