The 1982 Mack Ms300p has 2 NHTSA recall campaigns affecting an estimated 7,186 vehicles. Recall repairs are always free at any authorized dealer. Last updated July 5, 2026.
BOLTED INSTALLATION OF THE STEERING GEAR HOUSING HAS A TENDENCY TO LOOSEN IN SERVICE. THIS IS DUE TO A BACKWARD INSTALLATION OF THE LOCKWASHERS, WHICH ARE BELLVILLE TYPE, AND A RESULTANT INCORRECT TORQUE ON THE BOLTS.
ALL RECALLED VEHICLES WILL HAVE BELLVILLE TYPE LOCKWASHERS AT STEERING GEAR HOUSING ATTACH POINTS REPLACED WITH STANDARD SPLIT-TYPE LOCKWASHERS.
THE CIRCUIT WIRING ON THESE VEHICLES IS ARRANGED SO THAT A SHORT CIRCUIT IN THE REAR TAILLIGHTS WILL ALSO RESULT IN LOSS OF POWER TO THE HEADLAMPS. FOR SAFETY REASONS THE LIGHTING SYSTEM WIRING SHOULD BE INDEPENDENT.
VEHICLES WILL HAVE AN AUTOMATIC RESET CIRCUIT BREAKER INSTALLED TO ENSURE CONTINUED HEADLAMP ILLUMINATION IN THE EVENT OF A SHORT IN OTHER LIGHTING SYSTEMS.
