STEERING
DESCRIPTION
CAUTION: Use approved fluid only in the power
steering system (Refer to LUBRICATION & MAINTE-
NANCE/FLUID TYPES - DESCRIPTION). No other
power steering or automatic transmission fluid is to
be used in the system. Damage may result to the
power steering pump and system if any other fluid
is used, and do not overfill.
Power steering systems consist of:
²Steering column
²Rack and pinion steering gear
²Belt driven hydraulic steering pump
²Pump pressure and return hoses
²Oil Cooler
OPERATION
The steering column shaft is attached to the gear
pinion. The rotation of the pinion moves the gear
rack from side-to-side. This lateral action of the rack
pushes and pulls the tie rods to change the direction
of the front wheels (Fig. 1).
Power assist is provided by an engine mounted
hydraulic pump which supplies hydraulic fluid pres-
sure to the steering gear.
DIAGNOSIS AND TESTING - POWER STEERING
SYSTEM
There is some noise in all power steering systems.
One of the most common is a hissing sound evident at
a standstill parking. Or when the steering wheel is at
the end of it's travel. Hiss is a high frequency noise
similar to that of a water tap being closed slowly. The
noise is present in all valves that have a high velocity
fluid passing through an orifice. There is no relation-
ship between this noise and steering performance.
