Summary of the Safety Concern:
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.

|
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. |
