Noise
|
Hissing Noise in Steering Gear
There is some noise with 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 being applied. There is
no relationship between this noise and steering performance. Do not
replace the valve unless the "hissing" noise becomes extreme. A
replaced valve will also make a slight noise, and is not always a
solution for the condition.
