THE ALUMINUM HUBS ON THE INVOLVED VEHICLES MAY BE SUBJECT TO FAILURE DUE TO CRACKS THAT MAY DEVELOP AROUND THE BASE OF THE INNER BEARING CUP. THESE CRACKS MAY SPREAD AROUND THE BARREL OF THE HUB AND MAY LEAD TO FRACTURE AND HUB SEPARATION. THE SEPARATED HUB IS RETAINED ON THE AXLE SPINDLE BY THE WHEEL BEARING ADJUSTING NUT.

ON THE INVOLVED VEHICLES, THE MOUNTING TABS USED TO MOUNT THE FIFTH WHEEL ASSEMBLY TO THE CHASSIS IN PLACE OF THE NORMAL CONTINUOUS ANGLE CONSTRUCTION COULD CRACK. THESE CRACKS CAN DEVELOP IN THE AREAS WHERE THE TABS ARE WELDED TO THE SIDE OF THE FIFTH WHEEL ASSEMBLY. IF THESE CRACKS GO UNDETECTED, THE FIFTH WHEEL COULD EVENTUALLY SEPARATE FROM THE CHASSIS.
