2006 F250 FRONT END SHIMMY, WOBBLE. TOOK TO DEALER FOR FRONT END CHECKUP AFTER LETTER FROM FORD. THEY SAID THEY AIRED UP THE TIRES AND IT WAS GOOD TO GO...? I WENT 5 MI DOWN THE ROAD AND SAME ISSUE HAPPENED AGAIN. HIT BUMP IN ROAD AND THEN ANOTHER THE TRUCK STEERING WAS OUT OF CONTROL. I ALMOST HIT ANOTHER CAR TRAVELING NEXT TO ME GOING DOWN THE HIGHWAY. SCARED TO DEATH.. I JUST PURCHASED THIS TRUCK IN FEB 2009 AS A FORD CERTIFIED TRUCK. I WANT TO GET RID OF THIS TRUCK. I BELIEVE IT IS A LEMON. DEALERSHIP JUST SAID TIRES WERE UNDER INFLATED, AT 65LB AND AIRED TO 70PSI?? DID NOT SOLVE PROBLEM. THIS TRUCK WAS TO PICK UP MY KIDS FROM SCHOOL, AND NOW I DON'T WANT TO DRIVE THEM IN IT AND I FEEL IT IS NOT SAFE. I WORK FOR FORD AND AM FEELING VERY DISCOURAGED AND THE HELP I AM RECEIVING? WHAT NOW, DO I KEEP TAKING BACK? *TR
MY 2006 F-250 WILL SHAKE SO VIOLENTLY WHEN YOU HIT A BUMP AT 30 TO 65 MPH IT RIPS THE STEERING WHEEL OUT OF YOUR HANDS AND YOU HAVE TO HIT THE BRAKES SO HARD AND COME TO A STOP TO GET IT BACK IN CONTROL. REPLACED THE STEERING STABILIZER HAD ALIGNMENT AND STILL DOES IT. *TR

I AM THE ORIGINAL OWNER OF A 2006 FORD F250 PICKUP. I PURCHASED THE VEHICLE NEW IN 2006. AT APPROXIMATELY THE 30,000 MILE MARK THE TRUCK STARTED TO EXPERIENCE A SEVERE SHIMMY AFTER DRIVING OVER A BUMP. THIS WOULD OCCUR RATHER RANDOMLY AND APPARENTLY UNDER ONLY THE PERFECT "BUMP OSCILLATION." ONCE THE SHIMMY STARTED THE IT WOULD GET WORSE UNTIL THE VEHICLE WAS NEARLY STOPPED. VERY DANGEROUS AND UNNERVING. SINCE IT WAS RANDOM AND INTERMITTENT AND I WAS VERY BUSY I PUT OFF TAKING THE VEHICLE INTO THE DEALER UNTIL SEVERAL THOUSAND MILES HAD PASSED AND THE SHIMMY EPISODES GREW MORE FREQUENT. AS A FORMER MECHANIC (CURRENT OCCUPATION IS ENGINEER), I STAYED ON TOP OF MAINTENANCE AND TIRE PRESSURES. AT APPROXIMATELY 37,000 MILES I TOOK THE VEHICLE INTO THE LOCAL FORD DEALERSHIP WHERE I PURCHASED IT FOR EVALUATION AND REPAIR OF THE SHIMMY. EVEN THOUGH THE VEHICLE WAS BARELY OUT OF WARRANTY THE DEALER CHARGED ME APPROXIMATELY $1000 TO FIX IT. THE REPAIRS APPEARED TO CORRECT THE SHIMMY AS IT HAS NO DONE SO IN THE 10,000 MILES SINCE THE REPAIRS. ON 4-22-09 I RECEIVE A LETTER FROM FORD MOTOR COMPANY STATING THAT FOMOCO AND NHTSA ARE STUDYING THIS CONDITION. SINCE I HAD A DIRECT EXPERIENCE WITH THE SITUATION AND HAVE VALUABLE INSIGHT TO HOW VEHICLE OPERATE I THOUGHT I WOULD PASS ALONG MY EXPERIENCE. FORD DID NOT CARE TO HEAR ABOUT IT AS THEY WERE WORRIED ABOUT ME ASKING FOR MY REPAIR MONEY TO BE RETURNED. SO NOW I AM CONTACTING YOUR AGENCY. IT IS VERY CLEAR TO ME THAT THIS IS NOT A TIRE INFLATION OR A SUSPENSION MODIFICATION CAUSED ISSUE AS THE LETTER ELUDED TO SINCE MY TRUCK HAS ZERO MODIFICATIONS, WAS ON THE ORIGINAL TIRES WHEN IT SHIMMIED, WAS REPAIRED AND CEASED SHIMMYING ON THE ORIGINAL TIRES, AND HAS SUBSEQUENTLY HAD 4 NEW TIRES INSTALLED AND DOES NOT SHIMMY. THE PROBLEM IS IN THE FRONT SUSPENSION GEOMETRY. THIS IS A VERY DANGEROUS CONDITION AND NEEDS TO BE ADDRESSED WITH MORE THAN A LETTER OF NOTIFICATION TO CHECK INFLATION PRESSURE. PLEASE CONTACT ME. *TR

I RECEIVED A NOTICE FROM FORD MOTOR CO. REGARDING A SHIMMY OR SEVERE VIBRATION THAT MAY OCCUR WHEN MY FORD F-250 FORD TRUCK TRAVELS OVER A BUMP OR DIP IN THE ROAD. THIS HAS HAPPENED TO ME. AT THE TIME I HAD NO IDEA WHAT CAUSED IT. I WAS TRAVELING AT APPROX. 65 MPH ON A HIGHWAY WHEN I DROVE TROUGH A DIP IN THE ROAD UNDER AN OVERPASS. MY TRUCK WENT IN A SEVERE SHIMMY. I ALMOST LOST FULL CONTROL OF THE TRUCK. HAD THERE BEEN A VEHICLE NEXT TO ME IN THE LEFT LANE I WOULD NOT HAVE BEEN ABLE TO AVOID HITTING IT. I DON'T KNOW WHAT THE PSI OF AIR IN MY TIRES WERE AT THE TIME. THEY WERE THE STOCK TIRES THAT CAME WITH THE TRUCK OFF THE LOT. I HAVE SINCE CHANGED THESE TIRES DUE TO WEAR. THIS IS A VERY SERIOUS ISSUE AND NEEDS TO BE GIVEN A LOT OF ATTENTION. *TR

OUR COMPANY RECEIVED A LETTER FROM FORD MOTOR COMPANY ADDRESSING AN ISSUE WITH F-SUPER DUTY 250/350 4X4. IT EXPLAINS HOW A SEVERE SHIMMY COMING FROM THE FRONT END CAN BE A PROBLEM. IT OFFERS A SOLUTION OF USING THE CORRECT TIRE PRESSURE. WE ARE A COUNTY OFFICE, UPKEEP AND MAINTENANCE IS FIRST PRIORITY AND TIRE PRESSURE IS CHECK WEEKLY AND ALWAYS MEETS MANUFACTURES RECOMMENDATION. THAT IS NOT A SOLUTION TO THIS PROBLEM. WHILE TRAVELING AT HIGHWAY SPEEDS, WHEN THE PICK-UP HITS A BUMP IN THE ROAD, IT TAKES ALL THAT I HAVE TO KEEP THE TRUCK ON THE ROAD! THIS I FEEL IS A SERIOUS DANGER! TIRE PRESSURE I FEEL IS A CHEAP ATTEMPT AT A SOLUTION. *TR

THE COMPLAINT I HAVE IS REGARDING THE F-250 SHIMMY. I HAVE BATTLED THIS FOR 2 YEARS. THE VIOLENT RATTLE OF THE TRUCK IS GOING TO GET MYSELF OR SOMEONE HURT IF NOT CORRECTED. I WOULD INVITE ANY DOUBTERS TO DRIVE MY TRUCK. AT SPEEDS OF 65-70 MPH, YOU HAVE TO COME TO A COMPLETE STOP IN-ORDER FOR THE VIBRATION TO STOP. ON INTERSTATE TRAVEL, IT IS NOT EASY TO GET PULLED OVER WITH TRAFFIC BEARING DOWN. THE LETTER FORD DISTRIBUTED YESTERDAY IS VERY TELLING, THAT THEY DO NOT KNOW HOW TO FIX, OR DO NOT WANT TO SPEND THE MONEY FOR A RECALL. THIS VIOLENT VIBRATION IS A DANGER, AND CONTINUES TO WORSEN. PARTICULARLY WITH THE TERRIBLE SHAPE OF TODAY'S INFRASTRUCTURE. PLEASE HELP FORD OWNERS ASAP. *TR
