7. Install the tie rod end to the knuckle, then tighten a new self-locking nut to the
specified torque.
Tightening torque: 29 +/- 4 N.m (21 +/- 3 ft-lb)
STATIONARY STEERING EFFORT CHECK 1. With the vehicle sto
pped on a flat and
paved surface, turn the steerin
g wheel to
CAUTION: Always use a new ball joint nut, as it is a self-
locking nut.

the straight ahead position.
2. Start the engine and allow to idle.
Standard value: 700 +/- 100 r/min
3. Attach a spring scale to the outer circumference of the steering wheel and
measure the steering force required to turn the steering wheel from the straight
ahead position to the left and right (within a range of 1.5 turns). Also check to
be sure that there is no significant change in the required steering effort.
Standard value:
Steering effort: 30 N (6.7 lb.) or less
Fluctuation allowance: 5.9 N (1.33 lb.) or less
4. If the measured value exceeds the standard value, refer to INSPECTION PROCEDURE 2: DIFFICULT STEERING WHEEL OPERATION (INSUFFICIENT POWER ASSIST)
.

STEERING WHEEL RETURN TO CENTER CHECK Conduct a road test:
1. Make both
gradual and sudden turns and check the s
teerin
g wheel return.

2. At a vehicle speed of approximately 35 km/h (22 mph), turn the steering wheel
90 degrees, hold a few seconds, then release. If the steering wheel then returns
70 degrees or more, the return can be judged as 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.)

FLUID LEVEL CHECK

Page 2854 of 3870
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.
