  4. 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

    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
