Recall Notes:
Mack campaign no sc072. Trucks equipped with eaton skid control system androckwell International ff931 or fl931 w front axles with aluminum wheel hubs. Possibility that full adjustment of the wheel speed sensor cannot be obtainedwith the present eaton wheel speed rotor. If this results in interferencebetween the rotor and sensor on only one wheel of the front axle and theinterferenceis sufficient to damage the sensor, then anti-wheel lock capabilitywill be lost on the front axle and the anti-wheel lock warning light indicatorwill activate, alerting the driver. However, in the event sensor-to-rotorinterference on both wheels of the front axle, and causes damage to bothsensor, the anti-wheel lock capability will be lost on the front axle, but theanti-wheel lock indicator warning light will not be activated. Absence of theanti-lock capability could result in impaired vehicle control should the driverundertake a panic stop in slippery road conditions. (correct by inspecting andreplacing eaton wheel rotors with improved parts and replace damaged sensos).
