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.

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.

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.

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.

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.

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.
