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.

Rattling or chucking noise
in the rack and pinion

Interference with hoses from vehicle body
Loose gear box bracket
Loose tie rod end and/or ball joint
Worn tie rod and/or ball joint
