1992 Ford B700 problems

What is wrong

The steering gears have an improperly machined snap ring groove. This can cause a fracture of the snap ring with subsequent damage to the recirculating ball guide tube. Also, the o-ring seal in vehicles built after february 1988 does not meet specifications and is inadequate, causing interior leakage around the o-ring / glide ring seal in the steering gear.

Risk

The fracture of the snap ring results in increasing deterioration of the ability to turn the vehicle to the right. The driver would experience increased steering efforts or a "crunchy" feeling at the steering wheel. The inadequate o-ring seal causes momentary reductions in power steering assist at low speed and certain left turn maneuvers. Both conditions result in decreased steering ability.

Remedy

Dealers will rebuild the steering gear. If a broken snap ring is found during rebuilding, the steering gear will be replaced with a remanufactured unit.

What is wrong

System: electrical system; battery. Vehicle description: medium duty school bus chassis equipped with hydraulic brakes, tilt hoods, 5.9l, 6.6l or 7.6l diesel engines or 6.1l or 7.0l gasoline engines and originally sold or currently registered in connecticut, illinois, indiana, maine, massachusetts, michigan, new hampshire, new jersey, new york, ohio, pennsylvania ,rhode island, vermont, and wisconsin. The battery power junction block mounted on the right fender apron, which serves as an electrical connection point for several engine compartment systems, is susceptible to road splash. The terminals at the junction block can experience corrosion and can fracture, causing loss of electrical power and engine shutdown.

Risk

Engine shutdown, loss of power steering assist, or loss of hydraulic brake boost can occur which may result in loss of vehicle control and an accident.

Remedy

Dealers will replace the junction box, main power terminal the starter or starter relay and terminals at the existing junction block. The wiring of the hydraulic brake circuit will also be modified by bypassing the junction block. The new terminals will be made from an alloy material more resistant to salt corrosion.

What is wrong

As a result of inherent vibration in these engines, the throttle return springs can fracture.

Risk

If one of the two return springs fractures while thevehicle is being driven, a substantial reduction in accelerator pedal effortwould be felt. If the second spring also fractures, the throttle would notreturn to idle position and can result in increased engine speed and thepossibility of loss of vehicle control and an accident.

Remedy

The throttle return control system with the coil torsion spring design will be replaced.
