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.
