INTRODUCTION TO POWER STEERING DIAGNOSIS
M1372008500061
Hydraulic power steering is used for all vehicles.
Faults in the power steering can include excessive
play of the steering wheel, difficult steering wheel
operation, noise, vibration, and oil leaks, etc.
Possible causes of these faults can include defects
in the gear box, oil pump or steering linkage.

SYMPTOM PROCEDURES
INSPECTION PROCEDURE 1: Excessive Play of Steering Wheel
DIAGNOSIS
STEP 1. Check for looseness at the steering shaft coupling
section and at the steering wheel linkage.
Q: Is there any looseness?
YES : Repair or replace the part. Then go to Step 3.
NO : Go to Step 2.

POWER STEERING DIAGNOSIS
STEP 2. Check the steering wheel free play.
(1) With engine running (hydraulic operation), set front wheels
straight ahead.
(2) Measure the play on steering wheel circumference before
wheels start to move when slightly moving the steering
wheel in both directions.
Limit: 30 mm (1.2 inch)
(3) If the free play exceeds the limit value, set steering wheel
straight ahead with engine stopped. Load approximately 5
N (1.1 pound) toward steering circumference and check

play.
Standard value (steering wheel play with engine
stopped): 10 mm (0.4 inch) or less
Q: Does the play exceed the standard value?
YES : Remove steering gear box (Refer to P.37A-23.) and
check total pinion torque (Refer to P.37A-25.). Then
go to Step 3.
NO : Go to Step 3.
STEP 3. Check steering wheel play.
Verify that the steering wheel play is not excessive.
Q: Is the steering wheel play excessive?
YES : Repeat to Step 1.
NO : Diagnosis is complete.
INSPECTION PROCEDURE 2: Difficult Steering Wheel Operation (Insufficient Power Assist)
DIAGNOSIS
STEP 1. Check the power steering belt tension.
Refer to GROUP 00, Maintenance Service - Drive Belts P.00-
40.
Q: Is the power steering belt tension within the standard
value?
YES : Go to Step 2.
NO : Adjust the tension. (Refer to GROUP 00,
Maintenance Service - Drive Belts P.00-40.) Then go
to Step 10.
STEP 2. Check the belt for damage.
Q: Is the belt damaged?
YES : Replace the belt. Then go to Step 10.
NO : Go to Step 3.

STEP 3. Check the fluid level.
(1) Park the vehicle on a flat, level surface, start the engine,
and then turn the steering wheel several times to raise the
temperature of the fluid to approximately 50 - 60◦ Jabse Service Manual Search 2024 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
