Every NHTSA safety campaign that lists a Mack Fdm, most recent first, with the model years each one covers.

  1. Gear box (other than rack and pinion) (steering)

    NHTSA 97V181000 Reported 109 vehicles potentially affected MACK TRUCKS, INCORPORATED

    Vehicle description: front discharge mixer chassis. The original equipment miter boxes have no protective boots on the shafts and dirt can enter the system causing the gear shaft bearings to deteriorate.

    Remedy: Dealers will replace these miter boxes.

    Model years: 1996, 1997

  2. Vehicle speed control

    NHTSA 94V032000 Reported 39,777 vehicles potentially affected MACK TRUCKS, INCORPORATED

    Fuel injection system reconfiguration to comply with engine emission standards cause higher engine vibration levels which lead to early wear and complete failure of the secondary throttle return mechanism.

    Remedy: A new production secondary throttle return system configuration will be installed.

    Model years: 1987, 1988, 1989, 1990, 1991, 1992

  3. Driveline (power train)

    NHTSA 93V176000 Reported 130 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The driveshaft to the front driving axle is secured to a bracket using two pillow blocks. These blocks are of insufficient strength to support the driveshaft and could fail.

    Remedy: Mack will install thicker pillow blocks and support u-bolts.

    Model years: 1989, 1990, 1991

  4. Fan (engine and engine cooling)

    NHTSA 93V137000 Reported 11,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The engine cooling fan blades may break due to inadequate blade strength around the rivets that attach the blades to the fan spider.

    Remedy: An improved fan will be installed on these vehicles.

    Model years: 1991, 1992, 1993
