CONDITION POSSIBLE CAUSES CORRECTION
Power steering pump growl results from the development of high pressure fluid flow. Normally this noise
should not be high enough to be objectionable. Abnormal situations, such as a low oil level causing
aeration or hose touching the vehicle body, can create a noise level that could bring complaints.
WHINE OR GROWL (PUMP
NOISE)1. Low fluid level. 1. Fill power steering fluid
reservoir to proper level and
perform leakage diagnosis.
(Recheck fluid level after power
steering fluid is free of air.)
2. Power steering hose touching
vehicle body or frame.2. Reposition power steering
hose. Replace hose if tube ends
are bent.
3. Extreme wear of power
steering pump internal parts.3. Replace power steering pump
and flush system.
SUCKING AIR SOUND 1. Loose clamp on power steering
fluid low pressure hose.1. Tighten or replace hose clamp.
2. Missing O-Ring on power
steering pressure hose
connection.2. Inspect connection and replace
O-Ring as required.
3. Low power steering fluid level 3. Fill power steering fluid
reservoir to proper level and
perform leakage diagnosis.
4. Air leak between power
steering fluid reservoir and power
steering pump.4. Inspect and/or replace power
steering fluid reservoir or supply
hose as required.
SQUEAK OR RUBBING
SOUND1. Sound coming from steering
column.1.Check for squeak in steering
column. Inspect for contact
between shroud, intermediate
shaft, column, and steering wheel.
Realign if necessary.Note: Check
steering column for noise
without clockspriing installed
and with the steering column
shaft removed from the steering
intermediate shaft. This must be
done before removing the
steering column for a noise
complaint.
2. Check for lack or grease on
steering column dash panel to
lower coupler seal.
2.Clockspring 3. Replace Clockspring
3. Sound internal to steering gear. 4. Replace steering gear
assembly.
SCRUBBING OR KNOCKING
SOUND1. Incorrect tire size. 1. Verify that tire size on vehicle is
the same as originally supplied.
2. Check clearance between tires
and other vehicle components,
through the full travel of the
suspension.2. Correct as necessary.
3. Check for interference between
steering gear and other
components.3.Correct as necessary.
4.Incorrect steering gear supplied. 4. Replace steering gear with
correct steering gear for specific
vehicle.
