THIS HAS HAPPENED ON SEVERAL OCCASIONS. IT IS CURRENTLY IN THE SHOP AND HAVING THE STEERING PUMP CHANGED. HOPE THIS CORRECTS THE ISSUE. *TR

WE WERE DRIVING IN A PARKING LOT AT A SLOW RATE OF SPEED WHEN THE STEERING LET LOOSE AND WE HAD NO CONTROL OF THE TRUCK. THE TRUCK CRASHED INTO A POLE IN THE LOT, AND WAS UNABLE TO BE MOVED DUE TO LOSS OF STEERING. IT HAD TO BE TOWED AWAY. HAD THIS BEEN A PARKING LOT WITH CARS AND OR PEOPLE THERE WOULD HAVE BEEN SERIOUS CONSEQUENCES. THE IMPACT FROM HITTING THE POLE, CAUSED MY WIFE'S NECK TO SNAP BACK AND SHE HAS SOME STRAIN IN HER NECK. ACCORDING TO THIS LINK FORD HAS BEEN HAVING TROUBLE WITH THEIR STEERING AND "DEATH BUMP" ACTION CAUSING THE TRUCKS TO SHIMMY OUT OF CONTROL- WE DID NOT HAVE ANY WARNING- JUST COMPLETE LOSS OF STEERING> THIS NEEDS TO BE ADDRESSED BEFORE SOMEONE IS KILLED. *TR

DRIVING DOWN THE HIGHWAY AND HIT A BUMP IN THE ROAD THE TRUCK STARTED TO DO THE DEATH WOBBLE AND SHAKING UNCONTROLLABLY. I HAVE TO SLOW DOWN AND JERK THE WHEEL TO GET IT TO STOP. ITS INCREASINGLY GETTING WORSE AND NOW DOING IT AT LOWER SPEEDS AROUND 25- 30MPH. THIS HAS ALMOST CAUSED WRECKS WITH VEHICLES REAR ENDING ME, OR WOBBLING IN THEIR DIRECTION. IT ALSO HAPPENED IN A NEIGHBORHOOD WITH CHILDREN PLAYING, I THOUGHT I WAS GOING TO HIT THE KIDS! THE BRAKES ALSO FAIL WHILE BEAKING AND HITTING A BUMP. THE TIRES ARE AT THE RECOMMENDED PRESSURE AND THAT IS NOT THE PROBLEM. THIS IS A VERY COMMON PROBLEM AS I HAVE SEEN WHILE DOING MORE RESEARCH. IM AFRAID THIS WILL EVENTUALLY CAUSE THE TRUCK TO ROLL OR WRECK. DONT LET THE LOSS OF LIFE OPEN THIS INVESTIGATION AGAIN.

I BOUGHT A 2006 FORD F-250 SUPERDUTY 4X4 IN 2008 WITH 11,300 MILES. SIX MONTHS AFTER BUYING TRUCK, I NOTICED ON THE HIGHWAY AT SPEEDS BETWEEN 60-70 MPH IF I HIT A SERIES OF BUMPS IN THE ROAD THE FRONT END STARTS TO SHAKE VIOLENTLY AND MUST SLOW DOWN TO 35-40 MPH TO STOP THE SHAKING. I STILL HAVE THE TRUCK FORD SENT ME A LETTER SAYING THERE ARE NO ISSUES BUT TO MAKE SURE TIRES ARE PROPERLY INFLATED AND BALANCED. THAT DOES NOT STOP THE VIOLENT SHAKING. I HAVE NOT HAD IT REPAIRED BECAUSE I HAVE READ SO MANY OTHER COMPLAINTS WHERE THEY HAVE SPENT THOUSANDS OF DOLLARS AND STILL HAVE THE ISSUE. I AM WAITING FOR FORD TO RECALL AND CORRECT THIS PROBLEM. I HAVE 32,000 MILES ON THE TRUCK NOW AND I AM VERY CAREFUL WHEN DRIVING ON THE HIGHWAY. *TR
