1978–1987 Mack Truck Recall

NOTE: THIS RECALL SUPERSEDES RECALL 8612 INITIATED IN JANUARY 1986. ON VEHICLES WITH ST34 OR ST38 SERIES REAR AXLES, THE SPRING EYE BOLTS ON THE TAPER LEAF SPRINGS MAY NOT HAVE BEEN TORQUED PROPERLY AND COULD FAIL DUE TO THE LOOSE FIT WITHIN THE SPRING EYE BUSHING/HANGAR BRACKET. THIS WOULD ALLOW THE SPRING TO FALL ON TO THE ROAD SURFACE CREATING A GREAT POTENTIAL FOR A VEHICLE CRASH DUE TO VEHICLE CONTROL PROBLEMS. CORRECTION: ALL 7/8 INCH DIAMETER SPRING EYE BOLTS WILL BE CONVERTED TO I INCH DIAMETER BOLTS.
