DEFECT #1 - WHEELS:CENTER SECTION
Posted on: 1996-03-12
Description
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.
Corrective Action
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.

DEFECT #2 - SERVICE BRAKES, HYDRAULIC:ANTILOCK
Posted on: 1996-09-25
Description
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.
Corrective Action
Dealers will inspect the abs wiring and, if necessary, properly connect.

DEFECT #3 - ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO-CHARGER
Posted on: 1994-08-17
Description
Four compression backplate retaining fasteners on the turbo-charger were torqued only hand tight. This allows the fasteners to loosen, and causes oil to leak into the compressor air side of the turbo-charger which, when coupled with the heat precipitated by the compressor and the mixing action of the compressor wheel, can result in an air/oil mixture that fuels the engine.
Consequence
When this occurs, engine run-on and subsequent loss of operator control via the normal throttle mechanism can occur, which could result in a vehicle accident.
Corrective Action
Replace the suspect turbo-charger with a new turbo-charger.
Notes
System: engine; turbo-charger.vehicle description: trucks and buses equipped with navistar i-6 engines.note: if your vehicle is presented to an authorized dealer on an agreed upon service date and the remedy is not provided within a reasonable time free of charge or the remedy does not correct the defect, please contact navistar at 1-800-448-7825.

The bottom edge of the accelerator pedal, when depressed, can come in contact with the head of a bolt securing the transmission cover to the floor. The engine throttle may not return to the idle position.
Consequence
