1) Lift-up the vehicle.
2) If a fluid leak is found, clean the fluid completely
from the suspect area, and turn the steering wheel
approx. 30 to 40 times to the left and right from lock
to lock, with the engine running, and check again
for leaks immediately, and also after a few hours
have passed.
3) Cause and solution for oil leakage from “a”
The oil seal is damaged. Replace the valve assem-
bly with a new one.
4) Cause and solution for oil leakage from “b”.
The torsion bar O–ring is damaged. Replace the
valve assembly with a new one.
5) Cause and solution for oil leakage from “c”.
The oil seal is damaged. Replace the valve assem-
bly or oil seal with a new one.
6) Cause and solution for oil leakage from “d”.
The pipe is damaged. Replace the faulty pipe or O-
ring.
7) Cause and solution for oil leakage from “g”.
The hose is damaged. Replace the hose with a
new one.
8) If leak is other than a, b, c, d or g, or if oil is leak-
ing from gearbox, move the right and left boots to-
ward tie-rod end side, respectively, with the
gearbox mounted to the vehicle, and remove fluid
from surrounding portions. Then, turn the steering
wheel from lock to lock about thirty to forty times
with the engine running, and make comparison of
the leaked portion immediately after and several
hours after this operation.
(1) Leakage from “e”
The cylinder seal is damaged. Replace the rack
bushing with a new one.
(2) Leakage from “f”
There are two possible causes. Perform the fol-
lowing step first. Remove the pipe assembly B
from the valve housing, and close the circuit us-
ing ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock ap-
prox. 30 to 40 times with the engine running,
then inspect the leaked portion immediately af-
ter and several hours after this operation.
•If leakage from “f” is noted again:
The oil seal of pinion & valve assembly is dam-
aged. Replace the pinion & valve assembly with a
new one. Or replace the oil seal and the parts that
are damaged during disassembly with new ones.
•If oil stops leaking from “f”:
The oil seal of rack housing is damaged. Replace
the oil seal and parts that are damaged during dis-
assembly with new ones.
F: ADJUSTMENT
1) Adjust the front toe.
SPECTION, Wheel Alignment.>
Standard of front toe:
IN 3 — OUT 3 mm (IN 0.12 — OUT 0.12 in)
2) Adjust the steering angle of the wheels.
Specification of steering angle:
3) If the steering wheel spokes are not horizontal
when wheels are set in the straight ahead position,
or error is more than 5° on the periphery of the
steering wheel, correctly re-install the steering
wheel.
4) If the steering wheel spokes are not horizontal
with vehicle set in the straight ahead position after
this adjustment, correct it by turning the right and
left tie–rods in the opposite direction from each oth-
er by the same angle.

Service limit:
Maximum load: 9.22 N (0.94 kgf, 2.07 lb) or
less
NOTE:
•A rather higher value may be indicated when pul-
ley starts turning.
•Measure the load during rotation to make a judg-
ment.
3. HYDRAULIC PRESSURE
NOTE:
•To measure hydraulic pressure correctly, be sure
to complete all the items in “INSPECTION”, prior to
performing the measurement. SPECTION, General Diagnostic Table.>
•Do not leave the valve of pressure gauge closed
or hold the steering wheel at lock for 5 seconds or
more in any case, this can damage the oil pump.
•Before attaching a pressure gauge, place a
wastecloth at locations where fluid can be expected
to spill. Wipe off any spilt fluid completely after the
measurement.
1) Regular pressure measurement
(1) Connect the ST1, ST2 and ST3.

(3) Disconnect the pipe C from pump.
(4) Using the gasket (Part No. 34621AC021)
and bolt (Part No. 34620AC010), install the ST2
to pump instead of pressure hose.
(5) Install the ST3 to the end of pressure hose
which is removed from pump.
(6) Replenish power steering fluid up to the
specified level.
(7) Open the valve, and start the engine.
(8) Measure the regular pressure.

9. Power Steering Fluid
A: SPECIFICATION
B: INSPECTION
1) Check the power steering fluid for deterioration
or contamination. If the fluid is highly deteriorated
or contaminated, drain it and refill with new fluid.
2) Check the joints and units for oil leakage. If any
oil leaks are found, repair or replace the applicable
part.
3) Inspect the fluid level of reservoir tank with vehi-
cle on level surface and engine stopped.
If the level is at “MIN. ” point or below, add fluid to
keep the level in the specified range of the indica-
tor. If at “MAX. ” point or above, drain fluid by using
a syringe or the like.
(1) Check at power steering fluid temperature
20°C (68°F); read the fluid level on the “COLD”
side.
(2) Check at power steering fluid temperature
80°C (176°F); read the fluid level on the “HOT”
side.
C: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the crossmember support.
3) Remove the pipe joint in the center of gearbox,
and connect the vinyl hose to the pipe and joint.
Wipe fluid off while turning the steering wheel.
4) Add the specified fluid to reservoir tank at “MAX”
level.
5) Continue to turn the steering wheel slowly from
lock to lock until the bubbles stop appearing on oil
surface while keeping the fluid at the level in the
Step 4).
6) If the steering wheel is turned in a low fluid level
condition, air will be sucked into the pipe. If sucked,
leave it about half an hour and then do the step 5)
again.
7) Start the engine and let it idle.
8) Continue to turn the steering wheel slowly from
lock to lock again until the bubbles stop appearing
on oil surface while keeping the fluid at the level in
Step 4).
Normally bubbles will stop appearing after turning
the steering wheel from lock to lock three times.
9) In case bubbles do not stop appearing in the
tank, leave it about half an hour and then do the
step 4) all over again.
10) Lower the vehicle, and then idle the engine.
11) Continue to turn the steering wheel from lock to
lock until the bubbles stop appearing and change of
the fluid level is within 3 mm (0.12 in).
12) In case the following happens, leave it about
half an hour and then do step 8) to 11) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the
fluid.
(3) Grinding noise is generated from oil pump.
13) Check the fluid leakage after turning steering
wheel from lock to lock with engine running.

POWER ASSISTED SYSTEM (POWER STEERING)
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.
Relief valve emits operating sound when steering wheel is
completely turned in either direction. (Do not keep this
condition over five seconds.)
Normal
Relief valve emits operating sound when steering wheel is
not turned. This means that the relief valve is defective. Replace the oil pump.
Rattling noise (intermittent)
While engine is running.
Interference with adjacent parts
Check the clearance.
Correct if necessary.
