NO: The procedure is complete.
INSPECTION PROCEDURE 9: VIBRATION DIAGNOSIS
STEP 1. Check the tires for out-of-balance.
Q: Is the check result OK?
YES: Go to Step 2.
NO: Balance the tires (Refer to WHEEL BALANCE ACCURACY
).
Then go to Step 4 .
STEP 2. Check the fluid level.
1. Park the vehicle on a flat, level surface, and then start the engine.
2. Turn the steering wheel several times to raise the temperature of the fluid
to approximately 50 - 60°C (122 - 140°F).
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.
Q: Is the check result OK?
YES: Go to Step 3.
NO: Bleed the air (Refer to POWER STEERING SYSTEM AIR
BLEEDING
). Then go to Step 4 .
NOTE: A slight vibration may be felt when the stationary steering
effort is made due to the condition of the road surface. To
check whether the vibration actually exists or not, test-drive
the vehicle on a dry concrete or asphalt surface. A very
slight amount of vibration is not a malfunction.

NO: Go to Step 4.
STEP 4. Retest the system.
Confirm that there is no steering wheel vibration.

YES: Repair or replace it. Then go to Step 2.
NO: Go to Step 2.
STEP 2. Retest the system.
Check that no oil is leaking.
Q: Is there oil leakage?
YES: Repeat from Step 1 .
NO: The procedure is complete.
INSPECTION PROCEDURE 12: OIL LEAKAGE FROM OIL RESERVOIR DIAGNOSIS
STEP 1. Check the oil reservoir for damage.
Q: Is there damage?
YES: Repair or replace it. Then go to Step 2.
NO: Go to Step 2.
STEP 2. Check for overflowing.
Q: Is there oil overflowing from the reservoir?
YES: Adjust fluid level. Then go to Step 3.
NO: Go to Step 3.
STEP 3. Retest the system.
Q: Is there oil leakage?
YES: Repeat from Step 1 .
NO: The procedure is complete.

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 (122 - 140°F).
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 fluid contains air or has milky appearance, or the fluid level fluctuate by
5 mm (0.2 inch) or more, power steering system air bleeding should be done.

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 IGNITION COIL
).
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 GENUINE MITSUBISHI POWER STEERING
FLUID up to the lower mark of the reservoir, and then bleed the air.

Perform air bleeding procedure as necessary after replacing the steering gear, oil
pump or the steering fluid lines.
1. Raise and support the front wheels.
2. Disconnect the ignition coil connectors (Refer to IGNITION COIL
).
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 IGNITION COIL
).
5. Start the engine and allow to idle.
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 the high and
low dipstick marks.
8. Confirm that there is very little change in the fluid level when the steering
wheel is turned left and right.
9. Confirm that the change in the fluid level is no more than 5 mm (0.2 inch)
when the en
gine is sto
pped.
CAUTION: Perform air bleeding only while cranking the
engine. Do not perform air bleeding while the
en
gine is runnin
g. If
you do so, air in the fluid will
be increased and air bleeding will become more
difficult. During air bleeding, refill the steering
fluid so that the level never falls below the lower
mark on the dipstick.
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 reduce
the life of the power steering components.
