- Component:
- Suspension:rear:springs:air suspension system
- Manufactured:
- 12/31/1989 - 02/28/1993
- Affected:
- 193
- Defect:
- The pressure relief valve was omitted in the air tank. the air tank is the reservoir for the air suspension and is not brake related. without the pressure relief valve, there is no back-up system to limit air pressure in the air suspension system.
- Consequence:
- Lack of a back-up system to limit air pressure build upcan cause excessive pressure in the air tank and can cause the tank to rupture.this can result in personal injury to anyone in the vicinity.
- Correction:
- Install a pressure relief valve in the air tank.
- Notes:
- System: suspension.vehicle description: school buses: models 4700 and 4900; heavy trucks: models3600, 3700, 3800, and 3900fg; incomplete chassis: model 1652sc.

- Component:
- Wheels:center section
- Manufactured:
- 02/28/1993 - 01/31/1996
- Affected:
- 206
- Defect:
- The front wheel hub can develop cracks at the wheel mounting studs. when mounted to the hub, the hydraulic brake disc rotor does not properly support the hub at the wheel studs causing excessive stress and fatigue cracks in the hub.
- Consequence:
- Should sufficient cracks occur, the mounting flange portion of the hub along with the wheel could separate from the vehicle without warning. should this occur while the vehicle is driven, the driver could lose control of the vehicle and/or the separated wheel and hub could strike another vehicle, pedestrian or property.
- Correction:
- Dealers will install new, redesigned hubs on these vehicles.
- Notes:
- System: wheels; hub. vehicle description: school and transit buses and medium duty trucks built with 9,000, 10,000, 11,000 or 12,000 pound front axle, hydraulic disc brakes, and hub mounted disc wheels. note: owners who take their vehicles to an authorized dealer on an agreedupon service date and do not receive the free remedy within a reasonable time, should contact navistar at 1-800-448-7825. also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.
- Campaign:

- Component:
- Service brakes, hydraulic:antilock
- Manufactured:
- 01/29/1992 - 09/02/1996
- Affected:
- 580
- Defect:
- The wiring from the electronic control unit was connected to the wrong wheel sensor or to the wrong brake modulator valve. it is possible that either or both wiring may have occurred at either the front or rear axle or both axles.
- Consequence:
- Should the anti-lock braking system (abs) wiring be crossed, it would result in a significant degradation in vehicle stopping distance. a signal would be sent to the wrong brake chamber when a brake imbalance is detected. this condition increases the risk of a vehicle accident.
- Correction:
- Dealers will inspect the abs wiring and, if necessary, properly connect.
- Notes:
- Owner notification:owner notification is expected to begin october 8, 1996.note: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 navistar at 1-800-448-7825.also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.

- Manufactured:
- 12/31/1980 - 07/31/1994
- Affected:

- Defect:
- These buses have a turn signal lever that will not operate consistently in the lane change mode if the lever is not moved to the position where resistance to movement is felt.
- Consequence:
