GENERAL INFORMATION
STEERING SYSTEM AND COMPONENT
DESCRIPTION
This vehicle comes with power steering as stan-
dard equipment and is the only steering system
available.
The power steering system consists of these six
major components. Power Steering Pump, Power
Steering Gear, Power Steering Reservoir, Power
Steering Supply and Pressure Hoses, and Power
Steering Fluid Return Hose. Turning of the steering
wheel is converted into linear travel through the
meshing of the helical pinion teeth with the rack
teeth. Power assist steering is provided by an open
center, rotary type control valve. It is used to direct
oil from the power steering pump to either side of the
integral steering rack piston.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As steering
effort increases as in a turn, the torsion bar twists,
causing relative rotary motion between the rotary
valve body and valve spool. This movement directs
oil behind the integral rack piston, which in turn,
builds up hydraulic pressure and assists in the turn-
ing effort.

DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING
STEERING SYSTEM DIAGNOSIS CHARTS
STEERING NOISE
One of the most common is a hissing sound evident
at standstill parking. Hiss is a very high frequency
noise similar to that experienced while slowly closing
a water tap. The noise is present in every valve and
results in high velocity fluid passing valve orifice
edges. There is no relationship between this noise
and performance of the steering. Hiss may be
expected when steering wheel at end of travel or
slowly turning at standstill.
