Consumer Description

ON TUESDAY, JULY 19 OF 2011, I OBSERVED THAT THE 5TH WHEEL BOLTS ON ABF UNIT NUMBER 19223 WERE LOOSE ENOUGH TO BE TURNED BY HAND. THE BOLTS ARE NOT BEING INTERFERED WITH BY THE HUCK RIVETS BELOW THEM. THE NUTS ARE PREVAILING TORQUE LOCK NUTS AND ARE NOT LOOSE ON THE BOLTS. THE BOLTS HAVE STRETCHED UNDER LOAD. I WAS GOING TO SHOW THE UNIT TO THE DIRECTOR OF MAINTENANCE, WHO HAPPENED TO BE IN OUR SHOP THAT DAY. UNFORTUNATELY, UNIT 19223 WAS SENT OUT BEFORE I COULD SHOW HIM. I DID, HOWEVER, MAKE A VIDEO OF ME TURNING THE LOOSE BOLT BY HAND. THIS IS ONLY ONE OF HUNDREDS OF ABF MACKS FROM 2009 AND 2010 THAT HAVE 5TH WHEEL BOLTS THAT ARE YIELDING UNDER LOAD.
