DESCRIPTION
The manual rack-and-pinion steering gear is sealed against the entry of water or foreign material by rubber boots enclosing the tie rod inboard ends at each end of the housing and by a third boot surrounding the pinion shaft and steering column intermediate shaft. The steering gear is lubricated at assembly and must be removed and disassembled if lubrication becomes necessary.
The rack is positioned and guided in the housing by a bushing at the right end and a support yoke holding it in engagement with the pinion at the left end. The support yoke is spring-loaded against the rack. A yoke plug and lock nut keeps the rack fully engaged with the pinion under load.
Rubber insulating mounts at each end of the housing cushion the steering gear mounting points and minimize vibration. Looseness or deterioration of the mounts can cause noise and vibration problems. These should be checked when investigating for such concerns.

The power steering system consists of
- Rack and pinion steering gear
- Power steering pump
- Fluid reservoir
- Interconnecting hydraulic lines
The power steering system uses a hydraulic pressure which is generated by the power steering pump to reduce the effort required to turn the steering wheel.
The power steering pump is mounted on the front of the engine. The pump has a vane-type design, and is driven by the crankshaft through a drive belt.
The power steering fluid is drawn into the pump from the reservoir when the engine is running. The fluid is pressurized by the rotation of the rotor and vanes, then sent to the steering gear. The fluid pressure is monitored and regulated by a Power Steering Pressure (PSP) switch and a control valve located in the power steering pump.
