WHILE DRIVING MY 2006 FORD F250 SUPER DUTY APPROX. 55MPH I HIT A BUMPY PART OF THE ROAD WHICH PUT THE VEHICLE IN AN UNCONTROLLABLE SHAKE. I WAS ABLE TO GET THE TRUCK STOPPED WITHOUT DAMAGE BUT HAD NO CONTROL OVER THE VEHICLE AND COULD ONLY BRAKE. HAD I BEEN IN A CORNER I DON'T THINK THERE IS ANY WAY I COULD HAVE STAYED ON THE ROAD. I CALLED THE FORD DEALER IN DAVENPORT IOWA AND WAS TOLD IT IS CALLED THE DEATH SHAKE AND THERE WAS NO KNOWN CAUSE FOR IT. I WILL GO AHEAD AND TAKE THE VEHICLE IN TO THE DEALER BUT HAVE NO CONFIDENCE IN THEM FIXING ANYTHING. I RECEIVED A LETTER FROM FORD STATING LOW TIRE PRESSURE COULD CAUSE THIS BUT MY TIRES WERE FINE. THERE WAS ALSO A PASSENGER WITH ME WHO HAS VERY SCARED WE WERE GOING TO WRECK. *TR

FRONT-END SHIMMY AFTER CROSSING UNEVEN OR SLIGHT ROUGH PAVEMENT AT HIGHWAY SPEED. PURCHASED TRUCK WITH 6500 MILES ON THE ODOMETER. AT THIS TIME, SHIMMY SEEMED TO BE INDUCED BY ROUGH PAVEMENT AT SPEEDS FROM 62 TO 75 MPH. RECEIVED A "RECALL" THAT STATED THE PROBLEM WAS WITH TIRE PRESSURE. I CHECKED MY TIRES AND FOUND MY PRESSURE TO BE 65 PSI. AS TRUCK MILEAGE HAS INCREASED, THE SHIMMY NOW STARTS AT 50 MPH ON ROUGHER PAVEMENT. THE FRONT TIRES ARE WORN EXCESSIVELY ON THE OUTSIDE EDGES BUT NOT THE INSIDE EDGES INDICATING THIS IS NOT A PRESSURE PROBLEM. THE SIPES ON THE SIDE OF THE PIRELLI SCORPIONS IS ALMOST GONE INDICATING OVER A QUARTER INCHED DIFFERENCE IN THE INSIDE VERSUS THE OUTSIDE EDGES. THE SHIMMY CAN BE SO BAD THAT MY ARMS HURT AFTER IT OCCURS. I WILL NOT LET MY WIFE DRIVE MY TRUCK AND HAVE LIMITED MY DRIVING TO DECREASE RISK. *TR

WITH ONLY 35,000 MILES ON IT, MY 2006 F-250 SD DIESEL TRUCK HAS DEVELOPED A FRIGHTENING BOUNCING IN THE FRONT END. ONCE IT HAPPENED GOING 65 MPH WHEN I HIT A FREEWAY POT HOLE. THE FRONT TIRE BOUNCED UP AND DOWN SO SEVERELY, THAT I PULLED OFF ONTO THE SHOULDER TO SEE IF SOMETHING HAD COME UNBOLTED. I HAVE EXPERIENCED THE SAME BOUNCING AT 40 AND 50 MPH FROM HITTING POT HOLES. FORD EVEN SENT ME AN ADVISORY ON THIS PROBLEM, CLAIMING THAT IT WAS RELATED TO INCORRECT TIRE PRESSURE. I HAVE BEEN FANATIC ABOUT TIRE PRESSURE, SO THAT WAS NOT INVOLVED. THE DEALER FOUND NOTHING WRONG WITH THE TRUCK AND CLAIMED THAT A $375 STEERING STABILIZER KIT WOULD CORRECT THE PROBLEM. WHY SHOULD I PAY FOR CORRECTING FORD'S DESIGN PROBLEMS? I AM JUST CONCERNED THAT THE BOUNCING COULD CAUSE ME TO LOSE CONTROL OF THE VEHICLE. *TR

THE LEFT FRONT WHEEL AND STEERING WHEEL SHOOK VIOLENTLY AND WOULD NOT STOP SHAKING UNTIL MY SPEED SLOWED FROM 70 TO 25 MPH. IT WAS NEARLY IMPOSSIBLE TO BRAKE WITH CONSTANT PRESSURE. I HAD TO FEATHER THE BRAKE TO SLOW THE VEHICLE. I INSPECTED THE VEHICLE TO THE BEST OF MY ABILITY AND SAW NOTHING OBVIOUSLY WRONG. THE SECOND INCIDENT OCCURRED IN THE RAIN IN THE DARK AT 70 MPH. MY WIFE WAS DRIVING AND WAS SCARED TO DEATH. BOTH INCIDENTS NEARLY CAUSED ACCIDENTS WITH VEHICLES BEHIND US. I INJURED MY LEFT SHOULDER ON THE FIRST ONE THAT'S WHY MY WIFE DROVE BACK. I RETURNED HOME AT 65-70 MPH AND HAD NO FURTHER INCIDENTS. I CHECKED THE TIRE PRESSURE ON THE 31 INCH BFG'S AND IT WAS ACCURATE AND WITHIN THEIR SPECS. *TR

I BOUGHT MY 2006 FORD F250, 4X4, CREW CAB DIESEL TRUCK IN SEPTEMBER OF 2005. I NEVER HAD A PROBLEM UNTIL I REACHED ABOUT 23K MILES. I WAS DRIVING ABOUT 45 MPH ON A TWO LANE HIGHWAY WHEN I WENT OVER SOME SMALL BUMPS IN THE ROAD. THE FRONT END STARTED SHAKING SO VIOLENTLY THAT I HAD A HARD TIME HOLDING ON TO THE STEERING WHEEL. WHEN I CAME TO A STOP OFF THE ROAD, I LOOKED FOR OBVIOUS SUSPENSION PROBLEMS BUT FOUND NONE. I DID SOME INTERNET SEARCHING AND FOUND THE "DEATH WOBBLE" THAT IS COMMON WITH THIS TRUCK. I SAW THE B.S. ABOUT TIRE PRESSURE BUT THAT WASN'T IT. I TOOK THE TRUCK TO A FRONT END SPECIALIST IN BUSINESS FOR OVER 40 YEARS. HE SAID THAT IT WAS THE STEERING DAMPENER AND HE HAD REPLACED SEVERAL ON THE FORDS. HE REPLACED MINE AND I HAVEN'T HAD A PROBLEM SINCE. LIKE EVERYONE ELSE, I THINK THIS PROBLEM IS AN ACCIDENT WAITING TO HAPPEN. I WOULD NOT EVEN DRIVE THE TRUCK UNTIL THE SPECIALIST FIXED THE PROBLEM BECAUSE IT SCARED ME SO BAD. OTHER THAN THAT, I LIKE THE TRUCK. HOPE IT DOESN'T HAPPEN AGAIN. *TR
