256 Power Steering
General
The power steering consists of an inte-
grated gear and hydraulic power cylinder,
and a power steering pump with fluid con-
tainer. The pump, driven by the engine,
provides hydraulic pressure to the power
steering. If the engine is not working, the
steering is only manual. With the power
steering not working, the effort required to
turn the steering wheel is much greater
than with power assist. If the power steer-
ing assist fails, bring the vehicle to a safe
stop. Do not drive the vehicle until correct-
ing the cause of the problem.
Do not drive the vehicle without power
assisted steering. When the power assist
has failed, the effort to turn the steering
wheel is much greater, especially in
sharp turns or at low speeds. This can
cause an accident and lead to serious
personal injury or death.
While operating the vehicle, avoid ruts and
obstructions which cause a binding condi-
tion on the sides of the front wheels. Drive
the vehicle out of the rut, then turn the
steering wheel. If possible, avoid turning
the wheels while the vehicle is at a stand-
still as this places a considerable load on
the power steering system and front axle.
