WHILE DRIVING MY 2006 FORD F250 FX4, AT SPEEDS BETWEEN 45-65 MPH, A SLIGHT VIBRATION IS FELT. WITHIN A FEW SECONDS IT TURN INTO A VIOLENT SHAKING MOTION AS IF I'M DRIVING ON LARGE COBBLE STONES. IT HAS BEEN SO BAD I HAVE ALMOST LOST CONTROL ON THE HIGHWAY AND CAME WITHIN INCHES OF HITTING ANOTHER VEHICLE. WHEN IT STARTS THERE IS NO STOPPING IT, AS THE STEERING WHEEL JERKS VIOLENTLY. FORD HAS SENT A LETTER OUT THAT SAY INFLATE YOUR TIRES AND IF IT STILL HAPPENS SLOW DOWN UNTIL IT STOPS. THAT'S NOT RIGHT. THIS IS DANGEROUS. I HAVE TO SLOW DOWN TO 30 MPH FOR IT TO STOP. I CAN'T DO THAT ON THE HIGHWAY. THE DEALERS AND FORD SAY THERE IS NOTHING THEY WILL DO. THIS ISSUE IS EXTREMELY DANGEROUS DUE TO FORDS ENGINEERING MISHAP.MY TIRES ARE STOCK, ROTATED, BALANCED, AND ALIGNED, THIS HAPPENS AT LEAST ONCE EVERY OTHER WEEK 2005-2013 F250,350 OWNERS REPORT THE SAME ISSUE. GOOGLE: FORD DEATH WOBBLE, AND WATCH THE F250 AT CRUISING SPEED. *TR

I HAVE A 2006 F250 LARIAT CREW CAB 6.0. THERE ARE NO MODIFICATIONS FROM STOCK ON THE VEHICLE. I WAS AND CONTINUE TO RUN RECOMMENDED AIR PRESSURE IN THE TIRES. WHILE DRIVING THE VEHICLE AT A SPEED OF 50 MPH IN A SLIGHT TURN, IMMEDIATELY AFTER HITTING A DIP IN THE ROAD, I EXPERIENCED A VIOLENT SHAKE IN THE FRONT END. IT FELT AS THOUGH THE TIRES WERE HOPPING WHICH MADE THE TRUCK EXTREMELY HARD TO CONTROL. AS THE FRONT END HOPPED IT PUSHED THROUGH THE TURN. THIS SEEMS TO BE IN INTERMITTENT CONDITION BROUGHT ON BY SPEEDS OVER 40MPH, IN TURNING SITUATIONS, WHERE THERE IS A BUMP AND OR DIP IN THE ROAD. BASED ON MY RESEARCH LATELY THIS SEEMS TO BE A KNOW SAFETY ISSUE THAT FORD HAS CHOSEN TO IGNORE. *TR

I HAD NEVER HEARD OF A DEATH WOBBLE UNTIL I WAS ON MY WAY TO THE HOSPITAL WITH MY THREE CHILDREN AFTER BEING INVOLVED IN A ROLLOVER ACCIDENT. WE WERE TRAVELING NORTH BOUND ON THE M53 VAN DYKE EXPRESSWAY WHICH HAS A POSTED SPEED OF 70 MPH. I HAD JUST PASSED A VEHICLE THAT WAS IN THE RIGHT LANE. JUST AFTER PASSING THIS VEHICLE I DEVELOPED THIS DEATH WOBBLE, I WAS SWITCHING LANES BACK TO THE RIGHT LANE WHEN MY STEERING WHEEL STARTED TO SHAKE, NOT JUST A LITTLE SHACKING EITHER. I HAD APPLIED MY BRAKES AND HELD THE WHEEL WITH BOTH MY HANDS. MY STEERING WHEEL WAS SHACKING SO BADLY THAT MY DASHBOARD WAS FALLING APART, AND I WAS HAVING MAJOR PROBLEMS CONTROLLING MY VEHICLE. IT FELT AS IF MY DRIVER?S WHEEL WAS BOUNCING UP AND DOWN AND MY STEERING WHEEL WAS ALSO SHAKING SO BADLY THAT IN JUST A SECOND I HAD LOST TOTAL CONTROL OF MY VEHICLE. MY TRUCK DRIFTED TO THE RIGHT AND MY LEFT FRONT WHEEL HIT THE TURF FOLLOWED BY MY LEFT REAR WHEEL HITTING THE TURF AND WE STARTED TO ROLL. WE ROLLED TWO IN HALF TIMES BEFORE COMING TO A STOP UPSIDE DOWN. THE CAB OF THE TRUCK WAS CRUSHED, THE RIGHT REAR CORNER OF THE CAB WAS PUSHED DOWN FURTHER THAN THE HEADRESTS ON THE SEAT WERE MY YOUNGEST WAS SITTING, AND THANK GOD MY 7 YEAR OLD WASN?T KILLED. ON THE PASSENGER?S SIDE THE ROOF WAS SMASHED AGAINST THE HEAD REST WERE MY DAUGHTER WAS SEATED. I AM VERY THANKFUL THAT MY 3 CHILDREN AND I LIVED THROUGH THIS NIGHT MARE. I HAVE DRIVEN A PICKUP TRUCK FOR OVER 20 YRS., AND I HAVE NEVER FELT THIS DEATH WOBBLE BEFORE.

THIS COMPLAINT IS FOR STEERING OSCILLATION, OR "DEATH WOBBLE". THE VEHICLE IN QUESTION IS COMPLETELY STOCK, WITH NO LIFT. THIS EVENT HAS OCCURRED NUMEROUS TIMES UNDER A VARIETY OF DRIVING CONDITIONS AND SPEEDS. THE VIOLENCE OF THIS HAPPENING WHILE DRIVING AT ANY SPEED IS FRIGHTENING AND DANGEROUS, PARTICULARLY AT 70 MPH ON THE INTERSTATE. FORD HAS ISSUED SEVERAL TECHNICAL BULLETINS RELATING TO THIS PROBLEM, BUT NO SOLUTIONS HAVE BEEN OFFERED BESIDES CHECKING YOUR TIRE PRESSURE. TO ME AND THE THOUSANDS OF CONSUMERS THAT HAVE HAD THIS PROBLEM, THAT SEEMS TO BE A CONVENIENT WAY TO SAY IT IS NOT A DESIGN PROBLEM THAT SHOULD BE CORRECTED, BUT OPERATOR ERROR. IT IS INCREDIBLE THAT SOMETHING THIS DANGEROUS AND POTENTIALLY LIFE THREATENING IS NOT BEING ADDRESSED BY THE NHTSA AND THAT FORD IS NOT BEING HELD ACCOUNTABLE FOR THEIR DESIGN PROBLEM. THIS IS A DANGEROUS SITUATION THAT NEEDS TO BE ADDRESSED. *TR

THE FRONT END OF THE TRUCK BEGINS TO VIOLENTLY SHAKE AT 60 MILES AN HOUR. SOMETIMES A BUMP CAUSES IT, OTHER TIMES IT OCCURS WHEN SIMPLY DRIVING STRAIGHT. HAVE HAD REGULAR SERVICE AT FORD DEALER, BUT THE ISSUE HAS GOTTEN PROGRESSIVELY WORSE OVER THE YEARS. HAVE ALERTED THEM OF THE PROBLEM FOR YEARS. IT'S ALL OVER THE INTERNET AS "FORD F250 FRONT END SHAKE" OR MORE CONCERNINGLY AS THE "FORD DEATH WOBBLE." IT'S NOT A TIRE PRESSURE ISSUE, AS I'VE ONLY USED PROPERLY INFLATED FACTORY TIRES THAT WERE DEALER INSTALLED. PROBLEM HAS CONTINUED TO GET WORSE, AND THE SHAKE HAS NOW MADE THE TRUCK VIRTUALLY UNDRIVABLE AT 60 MPH. PLEASE GOOGLE THE ISSUE. IT'S REAL. LOVE MY FORD, BUT MY FAMILY COMES FIRST, AND THE WOBBLE IS TOO SCARY TO IGNORE. JUST PAID ANOTHER $2800 TO TRY ANOTHER FIX (TRACK BAR AND BALL JOINTS), PLUS ANOTHER $2000 FOR NEW TIRES. SOMEONE WILL GET HURT WITH THIS. *TR

THE FAILURE WOULD ALSO OCCUR WHEN DRIVING OVER A SLIGHT ROAD BUMP. THE CONTACT TOOK THE VEHICLE TO THE DEALER WHERE THE FRONT SHOCKS, STRUTS AND STEERING STABILIZER WAS REPLACED, BUT THE REPAIRS DID NOT PERMANENTLY CORRECT THE FAILURE. THE VEHICLE WAS NOT FURTHER REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN, BUT THE CURRENT MILEAGE WAS 150,000.

I HAVE OVER 118 PAGES OF REPAIRS DEALING FROM ELECTRICAL, SUSPENSION, ENGINE FAILURE, TURBO, FLUID LEAKAGE, OIL COOLER FAILURE. EJECTORS, GLOW PLUGS AND COUNTING. THEY CONTINUE TO REOCCUR TIME AFTER TIME AND DEALER WILL NOT COVER. I MET ALOT OF CONSUMERS THAT HAS THE SAME VEHICLE AND THEY ALL ARE HAVING THE SAME PROBLEM. I KNOW THAT FORD HAS SUED THE DESIGNER OF THE 6.0 ENGINE AND WON BILLIONS BUT WILL NOT ATTEMPT TO ASSIST THE CONSUMER. THE RIGHT THING TO DO IS, IF YOU KNOW THAT IF THERE'S A PROBLEM WITH A PROBLEM WHY NOT ASSIST THE CONSUMER IN CORRECTING INSTEAD OF DOING A PATCH JOB. THEY WILL NOT ATTEMPT TO DO THE RIGHT THING UNLESS SOMEONE FORCE THEM TO DO SO. THANKS *TR
