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.
IF THE SPINDLE FAILS, A LOSS OF DRIVER CONTROL COULD OCCUR, INCREASING THE RISK OF A VEHICLE CRASH.
DEALERS WILL REMOVE THE LEFT AND RIGHT HUB/DRUM ASSEMBLIES FROM THE STEERING AXLES AND REPLACE THE INNER WHEEL BEARING CONES AND CUPS.
