Steering System

Steering System
The power steering system consists of the following components:
^ Power steering pump
^ Power steering fluid reservoir
^ Steering gear
^ Power steering fluid cooler
^ Power steering lines
^ Steering column
^ Steering column shaft

The power steering system transfers driver inputs at the steering wheel to the front wheels of the vehicle. The steering column, hydraulic system and linkages that transfer these driver inputs make up the steering system. Gearing and hydraulic assist are used to significantly reduce steering efforts.

The variable assist power steering (VAPS) system controls the level of power assistance available to the driver based on vehicle speed. At very low speeds, full power steering assist is provided to lessen steering efforts and increase maneuverability. At faster speeds, steering assist decreases gradually at a calibrated rate to raise steering efforts for increased directional stability and greater road feel.
