NHTSA Complaint #10294472 — 2007 FORD F-250 SD

I OWN A 2007 FORD F250 SUPER DUTY EXT CAB, I HAVE BEEN HAVING PROBLEMS WITH IT SHAKING/ BOUNCING VIOLENTLY WHEN I GO THROUGH A POTHOLE OR RUN OVER A BRIDGE SEAM WHEN TRAVELING OVER 60 MPH. THIS HAS HAPPENED MORE THAN A DOZEN TIMES UNDER DIFFERENT LOAD CIRCUMSTANCES PULLING A TRAILER, WITHOUT A TRAILER, FOUR ADULTS IN THE CAB ONLY MYSELF IN THE CAB, WITH AND WITHOUT A LOAD IN THE BED. I BOUGHT THE TRUCK NEW IN MAY OF 2007. THERE WERE SEVERAL TIMES I ALMOST HIT ANOTHER VEHICLE IN THE NEXT LANE BECAUSE OF THE STEERING WHEEL PULLING RIGHT TO LEFT OR THE TIRES BOUNCING UP AND DOWN AND WHEN I APPLY THE BREAKS THE TIRES SKID AT FIRST. I HAVE TO SLOW DOWN VERY FAST AND TO A VERY SLOW SPEED TO GET IT UNDER CONTROL. I HAVE HAD THE VEHICLE A LITTLE OVER 2 1/2 YEARS AND IT ONLY HAS 25,000 MILES. FORD SENT OUT LETTERS WARNING OF THIS PROBLEM AND SAID TO MAKE SURE THE TIRE PRESSURE WAS CORRECT AND EQUAL IN THE TIRES. I HAVE DONE THIS AND CONTINUE TO MAKE SURE IT IS CORRECT AND THE SAME. I HAVE TRIED REDUCING THE TIRE PRESSURE INCREMENTALLY FROM THE 75PSI RECOMMENDED ON THE VIN PLATE BUT THAT HAS NOT WORKED. *TR
