FRUEHAUF CORPORATION
The problem
AN INNER WHEEL BEARING CONE MAY BE MISSING ON SOME OF THESE TRAILERS.
Risk
WITHOUT AN INNER BEARING CONE, THE WHEEL USES THE OIL SEAL AS THE INNER LOAD SUPPORT. UNDER THIS LOAD, THE OIL SEAL DETERIORATES CAUSING THE OIL CONTAINED IN THE WHEEL CAVITY TO SEEP AND THE BRAKE DRUM TO RESTAND DRAG ON THE BRAKE LINING. DRAGGING BRAKES CAN CAUSE INADVERTENT OR ERRATIC BRAKING AND/OR OVERHEATING OF THE BRAKE DRUM WHICH, IN CONTACTING THE SEEPING OIL CAN START A FIRE IN THE AFFECTED WHEEL ASSEMBLY.
What owners should do
DEALERS WILL INSPECT ALL BRAKE COMPONENTS AND THE AXLE SPINDLE FOR ANY DAMAGE OR EXCESSIVE WEAR. DEALERS WILL REPLACE AND REPAIR AS REQUIRED.
