Reported: 1998-11-09 (November 9, 1998) · Model years: 1997, 1998, 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH SPICER SPL170 55MM CENTER BERING PACKAGE. THE END YOKE RETAINING NUT CAN LOOSEN.

Consequence: IF THIS CONDITION OCCURS, THE DRIVE LINE CAN VIBRATE AND SEPARATE FROM THE VEHICLE, CAUSING VEHICULAR DAMAGE, OR PERSONAL INJURY, OR BOTH.

Remedy: DEALERS WILL REMOVE THE 55MM CENTER BEARING PACKAGE AND COUPLER SHAFT, AND REPLACE IT WITH A NEW COUPLER SHAFT AND A 60MM CENTER BEARING PACKAGE. AN INTERIM REMEDY CAN BE IMPLEMENTED BY PLACING A SPOT WELD ON THE COUPLING SHAFT THREADS UNTIL PARTS ARE AVAILABLE.

Reported: 1999-03-15 (March 15, 1999) · Model years: 1998, 1999

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.

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.

Reported: 1999-05-04 (May 4, 1999) · Model years: 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH DANA/SPRAGUE WINDSHIELD WIPER ASSEMBLIES. THE KNURLED PIVOT SHAFT (WHICH OPERATES THE WINDSHIELD WIPER ARM) IS WELDED TO A LEVER, WHICH CONNECTS TO LINKAGE FROM THE WIPER MOTOR. THE WELD AT THE PIVOT SHAFT TO LEVER CAN FAIL.

Consequence: SHOULD A FAILURE OCCUR DURING INCLEMENT WEATHER ON THE DRIVER'S SIDE WHILE THE VEHICLE IS IN MOTION, THE OPERATOR'S VISION WOULD BE PARTIALLY OBSCURED.

Remedy: DEALERS WILL INSPECT THE WIPER SYSTEM, CONDUCTING A "STALL" TEST TO VALIDATE THE INTEGRITY OF THE WELD. ALL WIPER ASSEMBLIES FAILING THIS TEST WILL BE REPLACED.
