Operation - Power Steering System
Turning of the steering wheel is converted into lateral (side-to-side) travel through the meshing of the helical pinion teeth with the rack teeth within the steering gear. This lateral travel pushes and pulls the tie rods to change the direction of the vehicle's front wheels.
Power assist steering is provided by a belt-driven rotary type pump. It directs fluid through power steering hoses to the power steering gear where it is used to assist the driver's turning effort.
Manual steering control of the vehicle can be maintained if power steering assist is lost. However, under this condition, steering effort is significantly increased.
Refer to POWER STEERING GEAR for information on the operation of the speed-sensitive variable-effort power steering.
