2010 FORD F-350 SD Unknown Or Other Problems

DRIVING DOWN THE HIGHWAY, HIT AN UNEVEN SPOT ON THE ROAD AND THE TRUCK STARTING SHAKING HORRIBLY. I WAS GOING BETWEEN 50-55MPH. HAD TO SLOW DOWN AND TRY TO GET OFF TO THE SIDE. IT WAS VERY DIFFICULT TO GET OUT OF THE WAY IN A TIMELY MANNER. THIS HAS BEEN HAPPENING ON A DAILY BASES, NUMEROUS TIMES IN ONE TRIP. IT IS ONE OF THE SCARIEST THINGS I HAVE EVER EXPERIENCED. I'M SCARED FOR MYSELF, MY CHILDREN AND ALL OTHER DRIVERS. IT'S ONLY A MATTER OF TIME BEFORE THIS ISSUE CAUSES A SERIOUS IF NOT FATAL ACCIDENT. *TR

WHILE DRIVING OUR FORD SUPER DUTY F 350 ON NUMEROUS OCCASIONS , IFOUR FRONT TRIES OR TIRE HIT A BUMP WE LOOSE CONTROL OF OUR TRUCK IT SHAKES VERY VIOLENTLY UNTIL WE SHOW DOWN AND ARE ABLE TO PULL OVER. WE HAVE HAD THE FRONT END REPLACED, ALSO REPLACED DAMPER AND SHOCKS. THIS HAS NOT STOPPED THE ISSUE, AT THIS POINT WE WILL NOT PUT OUR FAMILY IN DANGER BY RIDING IN THIS VEHICLE.
