I HAVE HAD 4 INCIDENTS WHERE ON THE FREEWAY TRAVELING AT SPEEDS IN EXCESS OF 65 MPH THE VEHICLE BEGAN SHAKING AND SHIMMYING SO VIOLENTLY THAT THE TRUCK CHANGED LANES AND WAS BEYOND MY ABILITY TO CONTROL THE VEHICLE.

I OWN A FORD F-250 SUPER DUTY[2005] WITH 14,000 MILES ON IT. I HAVE HIT A SERIES OF SLIGHT BUMPS TRAVELING ON THE GARDEN STATE PARKWAY TRAVELING AT ABOUT 65 MPH. THE FRONT END OF THE TRUCK AND STEERING WHEEL SHOOK SO VIOLENTLY, I THOUGHT THE FRONT END OF THE TRUCK DIS-ENGAGED FROM THE REST OF THE BODY. THE STEERING WHEEL SHOOK SO VIOLENTLY I COULD HARDLY HOLD ON TO IT. I TOOK MY FOOT OFF THE GAS AND APPLIED THE BREAK VERY GENTLY. I MUST HAVE SLOWED DOWN TO 30 MPH BEFORE THE TRUCK BECAME UNDER CONTROL AGAIN. MEANWHILE THE CAR BEHIND ME HAD TO SLAM ON HIS BREAKS DO TO MY TRUCK BEING OUT OF CONTROL AND THE RAPID DE-ACCELERATION ON A MAJOR HIGHWAY. I HAD TO PULL OVER AS SOON AS I WAS ABLE TO CHECK WHAT I THOUGHT WOULD BE MAJOR FRONT END DAMAGE. AFTER ALL, WHAT COULD CAUSE SUCH A VIOLENT REACTION. ABSOLUTELY NOTHING TO BE SEEN. MY TRUCK WAS JUST SERVICED BY A FORD DEALERSHIP AS IT HAS BEEN SINCE I PURCHASED IT NEW. THIS HAS HAPPENED AT LEAST 4 TIMES TOTAL. I CANNOT STRESS TO YOU ENOUGH HOW VIOLENT THIS "SHIMMY" IS. THIS IS NO SHIMMY ! THIS IS LIKE RUNNING OVER A SERIES OF TELEPHONE POLES LINED UP IN THE ROAD. IT IS ALMOST IMPOSSIBLE TO HOLD ON TO THE STEERING WHEEL LET ALONE HAVE CONTROL OF THE TRUCK. THIS IS AN EXTREMELY DANGEROUS SITUATION THAT NEEDS TO BE CORRECTED ASAP OR SOMEBODY IS SURE TO DIE BECAUSE OF THIS FLAW. I WOULD BE AFRAID TO HAVE MY WIFE OR CHILDREN DRIVE THIS TRUCK AND HAVE THIS HAPPEN. THEIR LIVES WOULD SURELY BE IN DANGER. PLEASE DO SOMETHING TO CORRECT THIS SERIOUS PROBLEM, OR GET THIS DANGEROUS TRUCK OFF THE ROAD. *TR

I HAD VERY LITTLE TO NO CONTROL OF THE STEERING, AND THE BRAKING WAS ALSO VERY POOR. THE TRUCK SHOOK SO BAD THAT IT IMPAIRED MY VISION ALL I COULD DO WAS LET OFF THE ACCELERATOR AND HOLD ON TO THE STEERING WHEEL. THE TRUCK DRIFTED INTO THE LEFT LANE WHILE SLOWING. AROUND 35-40 MPH THE SHAKING WENT AWAY AND THE TRUCK ACTED NORMAL. I PULLED OFF THE ROAD AND INTO A MALL PARKING LOT AND CHECKED UNDER THE TRUCK FOR ANYTHING OBVIOUSLY WRONG AND FOUND NOTHING. I DROVE MY TRUCK HOME ABOUT 10 MILES NO MORE PROBLEMS. WHAT A VERY SCARY EPISODE. *TR

THIS HAPPENED TWICE IN A 2 MILE PERIOD. I THEN DROVE ON SHOULDER OF THE ROAD AT 20 MPH TO GET HOME. THIS HAS BEEN A CONSISTENT PROBLEM SINCE I BOUGHT THE TRUCK NEW IN 2005 BUT IT HAS NEVER BEEN THIS BAD. I ORIGINALLY THOUGHT IT WAS BECAUSE IT WAS A 4 WHEEL DRIVE. I AM NOW NOT WILLING TO DIVE AT HIGH SPEEDS. THIS IS A SUPER DANGEROUS PROBLEM!!! *TR
