Power Steering System
The steering gear system includes the power steer-
ing gear, hydraulic hoses, power steering pump, res-
ervoir, and other components. Some models are also
equipped with a separate hydraulic power cylinder on
the right side of the front axle, or a right-hand slave
gear (such as the TRW RCH-45). The power steering
pump, driven by the engine, provides the power as-
sist for the steering system. If the engine is not run-
ning, there is no power assist. If the power-assist
feature does not work due to hydraulic fluid loss,
steering pump damage, or some other cause, bring
the vehicle to a safe stop. Do not drive the vehicle
until the cause of the problem has been corrected.
When there is no load on the vehicle, and the front
tires are pointed straight ahead, the steering wheel
spokes should be centered, ±10 degrees, as shown
in
Fig. 16.1. See Group 46 of the 122SD and
Coronado Workshop Manual for steering adjustment
procedures.
WARNING
Driving the vehicle without the power-assist fea-
ture of the steering system requires much greater
effort, especially in sharp turns or at low speeds,
which could result in an accident and possible
injury.
NOTICE
Never steam clean or high-pressure wash the
steering gear. Internal damage to gear seals, and
ultimately the steering gear, can result.
Drivers should carefully use the power available with
a power steering system. If the front tires become
lodged in a deep chuckhole or rut, drive the vehicle
out, instead of using the steering system to lift the
tires from the hole. Also, avoid turning the tires when
they are against a curb, as this places a heavy load
on steering components and could damage them.
