I OWN A 2006 F250 SD WITH 8000 MILES ON IT AND I CANT DRIVE IT AND FEEL SAFE ANYMORE. EVERYTIME I DRIVE ON ANY UNEVEN PAVEMENT OVER 50 MILES PER HOUR THE STEERING WHEEL IS OSCILLATING SO BADLY I HAVE TO SLAM ON THE BRAKES TO REGAIN CONTROL. IT IS SHAKING SO BADLY THE PASSENGER SIDE DOOR FLEW OPEN THE LAST TIME IT HAPPENED AND ALMOST HIT A VEHICLE PARKED ALONG THE ROADWAY. THE DEALERSHIP HAS NO CLUE WHAT IS THE PROBLEM. I SPENT OVER 37000 FOR THIS TRUCK AND NOW WHAT. I FEEL UNSAFE IN IT AND IT IS JUST A MATTER OF TIME BEFORE THE THING BREAKS THE WAY IT IS SHAKING. IT WILL PROBABLE TAKE ME WRECKING TO GET IT FIXED. *TR
