VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH A 1710 DRIVE LINE AND A 12 X 4 HYDRAULIC PARKING BRAKE. IF THE BRAKE DRUM OR TRANSMISSION YOKE ARE NOT FULLY SEATED WHEN THE EIGHT BOLTS ARE INSTALLED CONNECTING THE 3-PIECE JOINT, THE BOLTS CAN LOOSEN.

VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCK CHASSIS EQUIPPED WITH 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 NAVISTAR 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.

SCHOOL, TRANSIT, OR HEAVY DUTY VEHICLES EQUIPPED WITH SPICER 6,000 OR 8,000 LB. FRONT STEER AXLES. THE TIE ROD END CAN PULL OUTBOARD AND SEPARATE FROM THE TIE ROD TUBE DUE TO IMPROPER THREAD ENGAGEMENT BETWEEN THE MALE TIE ROD END AND THE FEMALE TUBE.

SEPARATION OF THE TIE ROD END COULD RESULT IN LOSS OF STEERING CONTROL, INCREASING THE RISK OF A VEHICLE CRASH.

DEALERS WILL REPLACE THE COMPLETE TIE ROD ASSEMBLY.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH T444E DIESEL ENGINES. A FUEL LEAK CAN OCCUR BECAUSE OF OVERCRIMPING OF THE HOSE END FITTINGS ON THE HOSE FROM THE REGULATOR TO THE LEFT HEAD AND THE HOSE FROM THE FUEL TRANSFER PUMP TO THE REGULATOR.

FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, CAN RESULT IN A FIRE.

DEALERS WILL INSPECT THE OIL HOSE AND PLACE AN ADDITIONAL CONVOLUTED LOOM AROUND THE EXISTING OIL HOSE, OR REPLACE THE HOSE ASSEMBLY.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH A T444E DIESEL ENGINE. THE HIGH PRESSURE OILLINE FOR THE FUEL INJECTION SYSTEM THAT GOES FROM THE HIGH PRESSURE OIL PUMP TO THE RIGHT CYLINDER HEAD CAN CHAFE AGAINST THE CHARGE AIR COOLER CROSSOVER PIPE.

IF THIS CONDITION OCCURS, THE HOSE WILL FAIL, RESULTING IN A SUDDEN LOSS OF OIL, CAUSING THE ENGINE TO HAVE A SUDDEN LOSS OF POWER.

DEALERS WILL INSPECT THE HOSES AND IF THE HOSE IS NOT DAMAGED A CONVOLUTED HOSE WILL BE PLACED OVER THE CURRENT HOSE. IF THE HOSE IS DAMAGED, IT WILL BE REPLACED ALONG WITH THE CONVOLUTED HOSE.
