Noise
Hissing Noise in Steering Gear
There is some noise in all power steering systems. One of the most common is a hissing sound when the steering wheel is turned and the car is not moving. This noise will be most evident when turning the wheel while the brakes are applied. There is no relationship between this noise and steering performance. Do not replace the valve unless the "hissing" noise is extremely objectionable. A replacement valve will also have a slight noise, and is not always a cure for the condition.
Rattling or chucking noise in rack and pinion
Interference with hoses from vehicle body

NOTE
A slight "grinding noise" may be heard immediately after the engine is started in extremely cold whether condition (below -20C): This is due to power steering fluid characteristics in extreme cold conditions and is not a malfunction.
