dard equipment and it is the only steering system
available. The power steering system consists of
these major components:
• Power Steering Pump
• Power Steering Gear
• Power Steering Fluid Reservoir
• Power Steering Fluid Supply Hose
• Power Steering Fluid Pressure Hose
• Power Steering Fluid Return Hose
For information on the first two components, refer

OPERATION
Turning of the steering wheel is converted into lin-
ear (side-to-side) travel through the meshing of the
helical pinion teeth with the rack teeth within the
steering gear. The 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 fluid 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 main-
tained if power steering assist is lost. However,
under this condition, steering effort is significantly
increased.
POWER STEERING FLUID HOSES
DESCRIPTION
The power steering fluid supply hose is a formed
hose that connects the power steering fluid reservoir
to the power steering pump. It is secured at both
ends using standard adjustable clamps.
