SOME 1993 SHORT WHEELBASE HALF-TON 4-WHEEL DRIVE PICKUP TRUCKS MAY HAVE BEEN BUILT WITH ONE-PIECE PROPSHAFTS HAVING TUBE TO YOKE WELDS OFF LOCATION. IN THIS CONDITION THE ATTACHMENT OF THE FRONT AND/OR REAR YOKE TO THE PROPSHAFT TUBE MAY NOT WITHSTAND NORMAL DRIVELINE TORQUE INPUTS CAUSING THE TUBE TO SEPARATE FROM THE YOKE. IF THE TUBE WERE TO SEPARATE FROM A YOKE WHILE THE VEHICLE WAS MOVING, THE PROPSHAFT COULD CAUSE DAMAGE TO THE UNDERBODY OF THE VEHICLE, OR POSSIBLY DETACH FROM THE VEHICLE.

TO PREVENT THIS CONDITION FROM OCCURRING, DEALERS ARE TO INSPECT THE VEHICLES TO DETERMINE IF A SAGINAW, THREE RIVERS PLANT, PROPSHAFT WAS INSTALLED AND IF SO REPLACE IT.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
