Steering System
Steering General Information
When there is no load on the vehicle and the front
tires are pointed straight ahead, the steering wheel
spokes should be at the 9 o'clock and 3 o'clock posi-
tions, or within 10 degrees to either side. See
Fig. 6.1. See Group 46 of the Walk-In Van Chassis
Workshop Manualfor steering adjustment procedures.

Power Steering System

The power steering system consists of a steering
gear (which includes a manual steering mechanism,
a hydraulic control valve, and a hydraulic power cyl-
inder), hydraulic hoses, power steering pump, reser-
voir, and other components. 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 hy-
draulic 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.
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.

Drivers should use the power available with a power
steering system carefully. 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.
Tilt/Telescope Steering Column
Lever Adjustment (optional)
To change the position of the steering wheel, pull the
lever upward and move the steering wheel to the de-
sired position. See Fig.
the position. The steering wheel can also be tilted up
to provide easier exit and reentry.

Adjustment
If the chassis is equipped with a telescoping steering
column, push the lever down and extend or retract
the steering wheel as desired.
WARNING
Make sure that the control lever is in the locked
(neutral) position before driving the vehicle.
Never tilt the column while driving the vehicle.
Doing so could cause loss of vehicle control and
result in personal injury and property damage.
