2002 International 4800 problems

Defect

Navistar, Inc. (Navistar) is recalling certain model year 1999-2002 International 4800 4x4 trucks manufactured June 30, 1999, through May 28, 2002, and equipped with Fabco TC-200 transfer cases. The field remedy that these vehicles received as part of Navistar recall 05501 (NHTSA recall number 03V-415), a double Cardan front driveshaft, may seize under certain conditions.

Consequence

If the double Cardan joint of the driveshaft seizes, the front driveshaft may separate and under certain conditions, potentially cause a front axle lockup, increasing the risk of a crash.

Remedy

Navistar will notify owners, and dealers will install front driveshaft guards at both ends of the shaft and lockout front wheel hubs. Any drive shaft that is found with loose or binding double Cardan joints at either end will be replaced, free of charge. The recall began on June 16, 2015. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 15506. Note: This recall supersedes recall 14V-520 which provided an interim-only remedy of disconnecting the front driveshaft.

Defect

ON CERTAIN 4X4 VEHICLES EQUIPPED WITH A FABCO TC-200 TRANSFER CASE, AN EXCESSIVE FRONT DRIVE SHAFT ANGLE MAY CAUSE ACCELERATED WEAR AND FAILURE OF THE DRIVE SHAFT AND RELATED COMPONENTS.

Consequence

THIS FAILURE CAN CAUSE THE FRONT DRIVE SHAFT TO BECOME SEPARATED FROM THE VEHICLE WITHOUT WARNING AND FALL INTO THE PATH OF OTHER VEHICLES ON THE HIGHWAY RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.

Remedy

DEALERS WILL INSPECT AND REPLACE THE EXISTING FRONT DRIVE SHAFT WITH A DOUBLE-CARDAN TYPE SHAFT. THE OWNERS WILL BE NOTIFIED BEGINNING ON FEBRUARY 28, 2005, CONCERNING THE FINAL REMEDY FOR THESE VEHICLES. OWNERS SHOULD CONTACT INTERNATIONAL TRUCK AT 1-800-448-7825. INTERIM NOTICES WERE MAILED TO OWNERS DURING DECEMBER 2003. AN ADDITIONAL INTERIM NOTICE WAS MAILED TO OWNERS DURING JULY 2004, ADVISING OWNERS OF THE REPAIR PROCEDURES BUT NO PARTS WILL BE AVAILABLE UNTIL DECEMBER 2004.

Defect

ON CERTAIN HEAVY DUTY TRUCKS, A BRASS FITTING CONNECTS THE DOUBLE CHECK VALVE TO THE BRAKE RELAY VALVE. WITH CERTAIN INPUTS TO THE VEHICLE, THE WEIGHT OF THE CHECK VALVE ON THE FITTING CAN CAUSE THE ASSEMBLY TO RESONATE. THE SUBJECT VIBRATION CAN CAUSE EXCESSIVE STRAIN LEVELS IN THE FITTING, WHICH COULD EVENTUALLY FATIGUE AND FAIL.

Consequence

IF THE FITTING BREAKS, THE REAR SERVICE BRAKES WILL CEASE TO OPERATE WITHOUT WARNING, RESULTING IN AN EXTENDED STOPPING DISTANCE, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL INSTALL A KIT TO REMOUNT THE DOUBLE CHECK VALVE WITH A FLEXIBLE HOSE ON THE MAJORITY OF VEHICLES. ON A SMALL NUMBER OF UNITS WITH CLEARANCE ISSUES OR TRACTION CONTROL, A KIT WITH A NEW RELAY VALVE THAT HAS A BUILT-IN DOUBLE CHECK VALVE WILL BE INSTALLED. OWNER NOTIFICATION BEGAN ON APRIL 18, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.
