DEFECT #1 - STEERING:GEAR BOX:SHAFT PITMAN
Posted on: 1992-10-30
Description
The saginaw gear does not relieve pressure when the wheels have been turned fully against the axle stops. The resulting continued pressure on the steering system can result in the development of cracks in the splines of the pitman shaft, which can develop into a complete fracture of the pitman shaft.
Consequence
Fracture of the pitman shaft causes complete loss ofsteering control, which could result in a vehicle accident if fracture occurswhile vehicle is in motion.
Corrective Action
Replace the existing pitman shaft in the steering gear assembly with a new, strengthened pitman shaft.

Consequence
Separation of the axle spindle from the axle housing can result in loss of vehicle control and a possible accident.
Corrective Action
Dealers will replace the rear axle housing with a new housing.
