418 MAINTENANCE AND LUBRICATION
POWER STEERING, GENERAL
The VN power steering consists of an integrated gear. The VHD vehicle has both the
integrated gear and the hydraulic power cylinder. There is also a power steering pump with
fluid container. 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 steering assist fails, bring the vehicle to a safe stop. DO NOT drive the
vehicle until correcting the cause of the problem.
While operating the vehicle, avoid ruts and obstructions which cause binding condition 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 standstill as this places a
considerable load on the power steering system and front axle.
Periodically check the power steering fluid reservoir and keep it filled to the proper level
with the recommended fluid. See the Operator’s Manual Vehicle Maintenance for more
information.
