The problem
THE OMISSION OF TWO WELDS THAT CONNECT THE PINTLE HOOK CROSSMEMBER ASSEMBLY TO THE TRAILER SUSPENSION SUBFRAME CAUSES FATIQUE CRACKS TO DEVELOP IN THE CROSSMEMBER. CONSEQUENCE OF DEFECT: PINTLE HOOK CROSSMEMBER COULD SEPARATE FROM THE SUSPENSION SUBFRAME RESULTING IN A TOWED VEHICLE BEING SEPARATED FROM THE LEAD TRAILER WITHOUT PRIOR WARNING. ALSO, LOOSENING OF FASTENERS THAT CONNECT THE BOGIE SUBFRAME TO THE BODY COULD RESULT IN SEPARATION OF THE BOGIE ASSEMBLY FROM THE TRAILER.
What owners should do
ADD MISSING WELDS, REPAIR/REPLACE BOLTS, AND INSTALL REINFORCEMENT GUSSETS, AS NECESSARY.
