THE "U"BOLTS THAT ATTACH THE DRIVE AXLES TO THE SUSPENSION APPEAR TO BE FAULTY. WE'VE HAD TWO BREAK ON TWO SPATE OCCASIONS IN LESS THAN A WEEK. BOTH TIMES THE TRUCK WAS LOADED WITH APPROXIMATELY 79000 LBS, WE DON'T RUN OVER WEIGHT, AND DRIVING. FIRST TIME WAS LEFT REAR DRIVE AXLE AND THE SECOND WAS ON THE RIGHT SIDE OF THE FORWARD DRIVE AXLE. WHEN PURCHASING NEW U BOLTS THE PARTS GUY MENTIONED THAT THEY'VE BEEN SELLING A LOT OF THEM SINCE THE WEATHER TURNED COLD. LUCKILY MY DRIVERS ARE VERY AWARE AND STOPPED AS SOON AS IT HAPPENED. I CAN ONLY IMAGINE WHAT WOULD HAPPEN IF AN AXLE BROKE LOOSE AT 65 MPH WITH A FULL LOAD ON THE TRUCK
