All Mack Mc Series recalls (6)

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

  1. Leaf spring assembly (suspension)

    NHTSA 84V036000 Reported 3,421 vehicles potentially affected MACK TRUCKS, INCORPORATED

    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.

    Remedy: The axle housing will be inspected and replaced, if necessary. The spring seats will also be replaced.

    Model years: 1978, 1979, 1980, 1981, 1982

  2. Steering wheel/handle bar (steering)

    NHTSA 84V033000 Reported 4,393 vehicles potentially affected MACK TRUCKS, INCORPORATED

    Improper steering clamp bolts and torque applied during installation. The bolt could fail, allowing the steering yoke to become loose.

    Remedy: Inspection and, if necessary, installation of proper steering shaft clamp bolts tightened to specifications.

    Model years: 1983, 1984

  3. Shaft pitman (steering)

    NHTSA 81V155000 Reported 225 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The pitman arm retaining bolt may not have been tightened to the required specifications due to a design change. Inadequate retention of the bolt to the output shaft could allow the pitman arm to loosen.

    Remedy: The dealer will inspect and, if necessary, retorque the retaining bolt to proper specifications at no charge.

    Model years: 1981

  4. Hand control/valve (service brakes)

    NHTSA 81V088000 Reported 10,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

    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.

    Remedy: The holes will be retooled to provide correct alignment and plastic knobs will be replaced by knobs of stronger material having metal reinforcements.

    Model years: 1979, 1980

  5. Body (structure)

    NHTSA 81V083000 Reported 180 vehicles potentially affected MACK TRUCKS, INCORPORATED

    The right hand front canopy cab mounting bracket interferes with the right hand brake chamber on the steering axle when in a certain degree turn and severe bumping is present.

    Remedy: The front canopy cab mounting bracket will be modified to allow for clearance of the right hand front brake chamber, without charge to owner.

    Model years: 1978, 1979, 1980, 1981

  6. Air (parking brake)

    NHTSA 80V052000 Reported 9,666 vehicles potentially affected MACK TRUCKS, INCORPORATED

    On certain vehicles, the knob that operates the tractor park valve may break off, rendering the valve inoperable.

    Remedy: Defective knobs will be replaced with an improved type, without charge to owner.

    Model years: 1979, 1980
