A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en
turning the steering wheel. In this case, start the vehicle with increasing engine speed than usual. If steering effort reduces nor-
mally, function is normal.

1. NOISE & VIBRATION
CAUTION:
Do not keep the relief valve operated over five seconds at any time or inner parts of the oil pump may
be damaged due to rapid increase of fluid temperature.
NOTE:
•A screeching noise may be heard immediately after the engine start in extremely cold conditions. In this
case, if the noise goes off during warm-up there is no abnormal function in the system. This is due to the fluid
characteristics in extremely cold condition.
•The oil pump normally makes a small whining noise due to its mechanism. Even if a noise is heard when
steering wheel is turned at stand still, there is no abnormal function in the system provided that the noise
eliminates when the vehicle is driving.
•When turning the steering wheel with the brake applied when the vehicle is parked, a screeching noise
may be generated by the brake disc and pads. This is not a fault in the steering system.
•There may be a small vibration around the steering devices when turning the steering wheel at standstill,
even though the component parts are operating properly.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise be-
cause of combined conditions, i.e., road surface and tire surface, engine speed and turning speed of steering
wheel, fluid temperature and braking condition.
These conditions do not indicate a problem in the system.
Confirm vibration for an AT model, by applying the parking brake on a concrete surface, shifting into the “D”
range, and turning the steering wheel repeatedly from slow to rapid, step by step.
Tr o u b l e P o s s i b l e c a u s e C o r r e c t i v e a c t i o n
Hiss noise (continuous)
While engine is running.

2. MEASUREMENT OF STEERING EFFORT
Step Check Yes No
1CHECK STEERING EFFORT.
1) Stop the vehicle on paved road.
2) Start the engine.
3) Run the engine at idle.
4) Install a spring scale on the steering wheel.
5) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
NOTE:When turning the steering more quickly than
necessary from a direction to the other direction
at an engine speed over 2,000 rpm, steering ef-
fort may be heavy. This is caused by flow char-
acteristic of the fluid in the oil pump and is not a
defect.
Is the steering effort less than
29.4 N (3.0 kgf, 6.6 lb)?
Go to step 2.Adjust the back-
lash.

1) Stop the engine.
2) Pull the spring scale at a right angle to the
steering wheel, and measure both right and left
steering wheel efforts.
Is the steering effort less than
294.2 N (30 kgf, 66.2 lb)?
Go to step 3.Perform the
adjustment.
3CHECK STEERING WHEEL EFFORT.

effort between right and left
less than 20%?
Go to step 5.Check, adjust and
replace if neces-
sary.

Measure the swing torque of the joint (yoke of
steering column side). INSPECTION, Universal Joint.>
Is the swing torque of the uni-
versal joint less than 7.3 N
(0.74 kgf, 1.64 lb)?
Go to step 6.Replace with a
new part.

Measure the swing torque of the joint (yoke of
gearbox side). Universal Joint.>
Is the swing torque of the uni-
versal joint less than 3.8 N
(0.39 kgf, 0.86 lb)?
Go to step 7.Replace with a
new part.
7CHECK FRONT WHEEL.
Check the front wheels.
Does the front wheels have
unsteady revolution or rattling,
or does the brake drag?
Inspect, readjust
and replace if nec-
essary.
Go to step 8.
8CHECK TIE–ROD ENDS.
Remove the tie–rod ends.
If the tie-rod ends of suspen-
sion have unsteady revolution
or rattling?
Inspect and
replace if neces-
sary.
Go to step 9.
9BALL JOINT CHECK.
Remove the ball joint.

have unsteady revolution or
rattling?
Inspect and
replace if neces-
sary.

ence between the right and left
sliding resistance less than
20%?

C: CAUTION
Please understand and adhere to the following general precautions. They must be strictly followed to avoid
any injury to the person performing the work or persons in the area.
1. OPERATION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Before disposing of shock absorbers, be sure to bleed the gas out completely. Also, do not expose to
flames or fire.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Use SUBARU genuine grease etc. or equivalent. Do not mix grease etc. with that of another grade or from
other manufacturers.
•Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
2. OIL
When handling oil, follow the rules below to prevent unexpected accidents.
•Prepare container and waste cloths when performing work which oil could possibly spill. If oil spills, wipe
it off immediately to prevent from penetrating into floor or flowing outside, for environmental protection.
•Follow all government regulations concerning disposal of refuse when disposing.
