WHILE TRAVELING ON HIGHWAY AND PULLING A TRAVEL TRAILER THE RIGHT REAR AXLE ON MY TRUCK BROKE CAUSING THE TRUCK TO ROLL FOUR TIMES. THE TRUCK HAD BEEN IN THE SHOP FOR WARRANTY REPAIR TO THE LEFT REAR AXLE WITHIN THE PAST MONTH DUE TO THE LEFT AXLE "FLAKING OFF" INTO THE REAR END. THE LEFT AXLE WAS REPLACED AT THAT TIME. I HAD RECEIVED A CELL PHONE CALL FROM FORD JUST A FEW HOURS BEFORE THE FAILURE AND I HAD INFORMED THEM THAT THE REAR END WAS MAKING THE SAME NOISE IT MADE BEFORE THE REPLACEMENT OF THE LEFT AXLE. I WAS SEVERELY INJURED IN THE ACCIDENT. THIS IS WHY THIS COMPLAINT IS LISTED. *JB
