POWER STEERING

DIAGNOSIS CHART (Cont'd.]
CONDITION
Gear Noise. ("Hissing" Sound)
CAUSE
There is s o m e noise in all
power steering systems. One
of the most common is a his-
sing sound most evident at
standstill parking. There is no
relationship between this noise
and performance of the steer-
ing. " H i s s " may be expected
when steering wheel is at end
of travel or when slowly turn-
ing at standstill.

CORRECTION
Do not replace valve unless
" h i s s " is extremely objec-
tionable. S l i g h t " h i s s " is
normal and in no way affects
steering. A replacement valve
will also exhibit slight noise
and is not always a cure for
the o b j e c t i o n . Investigate
clearance around flexible cou-
pling screws. Be sure steering
shaft and gear are aligned so
the flexible coupling rotates in
a flat plane and is not distorted
as shaft rotates. Any metal-
to-metal contact through the
flexible coupling will transmit
the valve " h i s s " into the car.
