1979 Mack F Series recalls
There are 2 NHTSA recall campaigns associated with this vehicle configuration.
Suspension › Rear › Springs › Leaf Spring Assembly
SPRING SEAT CAN DEFORM, WHICH CAUSES A DECREASE IN THE CLAMPING FORCE IN THE SUSPENSION ASSEMBLY. LOSS OF CLAMPING FORCE MAY BRING ABOUT AXLE MISALIGNMENT OR AXLE HOUSING FAILURE.
THE AXLE HOUSING WILL BE INSPECTED AND REPLACED, IF NECESSARY. THE SPRING SEATS WILL ALSO BE REPLACED.
Service Brakes, Air › Controls › Hand Control/Valve
THE RETAINING PIN FOR THE BRAKE CONTROL KNOB HAS BEEN MISALIGNED (OFF THE CENTER LINE OF THE VALVE PLUNGER HOLE). THIS CAUSES THE KNOB TO BE OVERSTRESSED AT THE RETAINING PIN HOLE AREA CAUSING IT TO SEPARATE FROM THE VALVE.
THE HOLES WILL BE RETOOLED TO PROVIDE CORRECT ALIGNMENT AND PLASTIC KNOBS WILL BE REPLACED BY KNOBS OF STRONGER MATERIAL HAVING METAL REINFORCEMENTS.
