Defect

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS BUILT WITH BENDIX AIR ABS WITH AN EC-17 1030R ELECTRONIC CONTROL UNIT (ECU), THERE HAVE BEEN REPORTS OF UNWANTED ABS ACTIVATION AT LOW SPEEDS CAUSED BY 1) CHAFED ABS WHEEL SPEED SENSOR WIRES ON ROTATING PARTS OR 2) A DAMAGED COMPONENT AT THE WHEEL END THAT GENERATES A CERTAIN TYPE OF ERRATIC SENSOR SIGNAL.

Consequence

THIS CONDITION COULD CAUSE THE ABS ECU TO EXHAUST THE AIR AT THE AIR BRAKE MODULATORS FOR ONE OR MORE OF THE WHEELS. THIS COULD RESULT IN EXTENDED BRAKING DISTANCES AND A POSSIBLE CRASH.

Remedy

DEALERS WILL REPLACE THE ABS ECU.

Defect

VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCK CHASSIS EQUIPPED WITH MACK 16,000 LB., 18,000 LB., OR 20,000 LB. HEAVY DUTY STEERING AXLES. THE INNER WHEEL BEARING CONE FOR THE STEERING AXLE WHEEL HUB ASSEMBLY DOES NOT PROPERLY FIT ONTO THE MACK STEERING AXLE SPINDLE ASSEMBLY. IMPROPER FIT OF THE BEARING TO THE SPINDLE INCREASES THE STRESS LEVELS TO THE STEERING AXLE SPINDLE WHICH COULD CAUSE SPINDLE FAILURE.

Consequence

IF THE SPINDLE FAILS, A LOSS OF DRIVER CONTROL COULD OCCUR, INCREASING THE RISK OF A VEHICLE CRASH.

Remedy

DEALERS WILL REMOVE THE LEFT AND RIGHT HUB/DRUM ASSEMBLIES FROM THE STEERING AXLES AND REPLACE THE INNER WHEEL BEARING CONES AND CUPS.
