WE LIVE ON A CURVE ROAD AND IT'S VERY DANGEROUS. WE TOOK IT TO THE DEALER IN FOLSOM CA, THEY REPLACED THE STEERING STABILIZER, WHICH DID NOT SOLVE THE PROBLEM.

I OWN A 2006 F250 4*4 AND WHILE DRIVING AT SPEEDS IN EXCESS OF 60 MPH THE TRUCK SHAKES VIOLENTLY AND EVEN SWAYS FROM LANE TO LANE, WHEN ENCOUNTERING ANY ROUGH PLACE IN THE ROADWAY. THIS IS A VERY VIOLENT SHAKING AND I HAVE BEEN FORTUNATE ENOUGH TO KEEP THE TRUCK FROM WRECKING. THE SHAKING WILL NOT STOP UNTIL YOU HAVE SLOWN DOWN DRAMATICALLY OR COME TO A STOP. FORD HAS COMMENTED THAT IT COULD BE THE AIR PRESSURE AND HAVE ORDERED A STEERING DAMPER TO TRY TO CORRECT THE PROBLEM. THIS TRUCK HAS DONE THIS SINCE DAY ONE AND WITH THE FACTORY TIRES AND THE NEW TIRES THAT I HAVE ON IT NOW. THIS PROBLEM NEEDS TO BE ADDRESSED BEFORE SOMEONE IS KILLED IN AN ACCIDENT RESULTING FROM THE DEFECT IN DESIGN.
