STEERING WHEEL RETURN TO CENTRE
CHECK
M1372001800317
Conduct a road test:
1. Make both gradual and sudden turns and check
the steering wheel return.
2. At a vehicle speed of approximately 35 km/h, turn
the steering wheel 90°, hold a few seconds, then
release. If the steering wheel then returns 70° or
more, the return can be judged satisfactory.
NOTE: There will be a momentary feeling or
"heaviness" when the wheel is turned quickly, but
this is not abnormal (Oil pump discharge amount
is especially apt to be insufficient during idling).
DRIVE BELT TENSION CHECKM1372001900392
For vehicles with 1300 and 1600 engine, refer to
GROUP 11A, On-vehicle Service − Drive Belt
Tension Check P.11A-7.
For vehicles with 2000 engine, refer to GROUP 11C,
On-vehicle Service − Drive Belt Tension Check
P.11C-7.
FLUID LEVEL CHECKM1372002000284
1. Park the vehicle on a flat, level surface.
2. Start the engine, and then turn the steering wheel
several times to raise the temperature of the fluid
to approximately 50 − 60°C.
3. With the engine running, turn the wheel all the
way to the left and right several times.4. Check the fluid in the oil reservoir for foaming or
milkiness. Check the difference of the fluid level
when the engine is stopped, and while it is
running. If the change of the fluid level is 5 mm or
more, air bleeding should be done.
FLUID REPLACEMENTM1372002100333
1. Raise and support the front wheels.
2. Disconnect the return hose connection, and then
connect a vinyl hose to the return hose, and drain
the fluid into a container.
3. Disconnect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38or P.16-39).
4. While operating the starter motor intermittently,
turn the steering wheel all the way to the left and
right several times to drain all of the fluid.
5. Connect the return hose securely, and then
secure with the clip.
6. Fill the oil reservoir with specified fluid up to
between "MAX" and "MIN" marks, and then bleed
the air.
Specified fluid: ATF DEXRON III or DEXRON
II
POWER STEERING SYSTEM AIR
BLEEDING
M1372002200330
Perform air bleeding procedure as necessary after
replacing the steering gear or the steering fluid lines.
1. Raise and support the front wheels.
2. Disconnect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38 or P.16-39).

ON-VEHICLE SERVICE
POWER STEERING37-14
CAUTION
Perform air bleeding only while cranking the
engine. If air bleeding is performed while the
engine is running, air could enter the fluid.
During air bleeding, refill the steering fluid
supply so that the level never falls below the
"MIN" mark on the oil reservoir.
3. Turn the steering wheel all the way to the left and
right five or six times while using the starter motor
to crank the engine intermittently several times
(for 15 to 20 seconds).
4. Connect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38 or P.16-39).
5. Start the engine (idling).
6. Turn the steering wheel to the left and right until
there are no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the
level is between "MAX" and "MIN" marks.
8. Confirm that there is very little change in the fluid
level when the steering wheel is turned left and
right.
CAUTION
If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled. If
air bleeding is not complete, there will be
abnormal noises from the pump and the
flow-control valve, and this condition could
cause reduce the life of the power steering
components.
9. Confirm that the change in the fluid level is no
more than 5 mm when the engine is stopped and
when it is running.
10.If the change of the fluid level is 5 mm or more,
the air has not been completely bled from the
system. The air bleeding procedure must be
repeated.
OIL PUMP PRESSURE TESTM1372002300315
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•MB990662: Power Steering Oil Pressure Gauge
•MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)
2. Bleed air, then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
− 60°C.
3. Start the engine and idle it at 1000 ± 100 r/min.
CAUTION
The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
4. Fully close the shut-off valve of the pressure
gauge and measure the oil pump relief pressure
to confirm that it is within the standard value
range. Open it again immediately after checking
the pressure.
Standard value: 8.8 − 9.5 MPa
5. If it is not within the standard value, replace the oil
pump.
6. Check whether or not the hydraulic pressure is
the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa

7. If it is not within the standard value, the probable
cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.
8. Turn the steering wheel all the way to the left or
right; then check whether or not the retention
hydraulic pressure is the standard value.
Standard value: 8.8 − 9.5 MPa
9. If not the standard value, overhaul the steering
gear. Remeasure fluid pressure.
10. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
11. Bleed the system (Refer to P.37-13).

times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
− 60°C.
3. The engine should be idling.
4. Disconnect the connector for the oil pressure
switch, and place an ohmmeter at the switch.
5. Gradually close the shut-off valve of the pressure
gauge and increase the hydraulic pressure, then
check whether or not the hydraulic pressure that
activates the switch is the standard value.
Standard value: 1.5 − 2.0 MPa
6. Gradually open the shut-off valve and reduce the
hydraulic pressure; then check whether or not the
hydraulic pressure that deactivates the switch is
the standard value.
Standard value: 0.7 − 2.0 MPa
7. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
8. Bleed the system (Refer to P.37-13).
TIE ROD END BALL JOINT DUST COVER
CHECK
M1372008600262
1. Press the dust cover with your finger to check
whether the dust cover is cracked or damaged.
2. If the dust cover is cracked or damaged, replace
the tie rod end.
NOTE: If the dust cover is cracked or damaged,
the ball joint could be damaged.
STEERING COLUMN SHAFT ASSEMBLY
SHOCK ABSORBING MECHANISM
CHECK
M1372013500090
If a collision accident occurs or severe impact is
applied on the steering wheel, the collision energy
absorbing mechanism may have operated. Once the
mechanism has operated, it will be inoperative even
it has suffered no apparent damage. Determine if the
steering column shaft can be reused by the following
procedure. If the collision energy absorbing
mechanism has already operated, replace the
steering column shaft assembly.
If any excessive radial free play on the steering
wheel is found with the tilt lever in the lock position,
always check the steering shaft assembly.
