(3) Install the oil pump housing assembly to the torque
converter clutch case, and secure evenly by tightening
four bolts.
Tightening torque:
41±3 N⋅m (4.2±0.3 kg-m, 30.4±2.2 ft-lb)
CAUTION:
Thoroughly remove the liquid gasket from the case
mating surface beforehand.
Use an old gasket or an aluminum washer so as not
to damage the mating surface of the housing.

(4) Rotate the drive pinion several times with ST1 and
ST2.

(5) Tighten the LH retainer until contact is felt while
rotating the shaft. Then loosen the RH retainer. Keep
tightening the LH retainer and loosening the RH
retainer until the pinion shaft can no longer be turned.
This is the“zero”state.
G3M0885
(6) After the“zero”state is established, back off the LH
retainer 3 notches and secure it with the lock plate.
Then back off the RH retainer and retighten until it
stops. Repeat this procedure several times. Tighten the
RH retainer 1-3/4 notches further. This sets the preload.
Finally, secure the retainer with its lock plate.
NOTE:
Turning the retainer by one tooth changes the backlash
about 0.05 mm (0.0020 in).

NOTE:

When left and right wheels are adjusted for toe-in at the
same time, moving one scale graduation changes toe-in by
approximately 4 mm (0.16 in).

Turn adjusting wheel and adjusting bolt equally in oppo-
site directions so that same scale graduations are posi-
tioned directly above center of the adjusting bolt.
3) Tighten self-locking nut.

5. REAR WHEEL TOE-IN (AWD MODEL)

Inspection
1) Using a toe-in gauge, measure rear wheel toe-in.
Toe-in: 0±3 mm (0±0.12 in)
2) Mark rear sides of left and right tires at height corre-
sponding to center of spindles and measure distance“B”
between marks.
3) Move vehicle forward so that marks line up with front
sides at height corresponding to center of spindles.
4) Measure distance“A”between left and right marks.
Toe-in can then be obtained by the following equation:
BA = Toe-in

Adjustment
1) Loosen self-locking nut on inner side of rear lateral link.
CAUTION:

When loosening or tightening adjusting bolt, hold
bolt head and turn self-locking nut.

Discard loosened self-locking nut and replace with a
new one.
2) Turn adjusting bolt head until toe-in is at the specifica-
tion.

NOTE:
When left and right wheels are adjusted for toe-in at the

1) Feed the specified fluid with its level being about 5 cm
(2.0 in) lower than the mouth of tank.
2) Continue to turn steering wheel slowly from lock to lock
until bubbles stop appearing in the tank while keeping the
fluid at that level.
3) In case air is absorbed to deliver bubbles into piping
because the fluid level is lower, leave it about half an hour
and then do the step 2) all over again.
4) Start, and idle the engine.
5) Continue to turn steering wheel slowly from lock to lock
again until bubbles stop appearing in the tank while keep-
ing the fluid at that level.
It is normal that bubbles stop appearing after three times
turning of steering wheel.
6) In case bubbles do not stop appearing in the tank, leave
it about half an hour and then do the step 5) all over again.
7) Stop the engine, and take out safety stands after jack-
ing up vehicle again.
Then lower the vehicle, and idle the engine.
8) Continue to turn steering wheel from lock to lock until
bubbles stop appearing and change of the fluid level is
within 3 mm (0.12 in).
9) In case the following happens, leave it about half an
hour and then do step 8) 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.

2. AIR TIGHTNESS CHECK
Start engine, and run it for 1 to 2 minutes, then turn it off.
Depress brake pedal several times applying the same
pedal force as that used in ordinary braking operations.
The pedal stroke should be greatest on the 1st depression,
and it should become smaller with each successive
depression. If no change occurs in the pedal height while
in a depressed state, brake booster is faulty.
NOTE:

In the event of defective operation, inspect the condition
of the check valve and vacuum hose.

Replace them if faulty and conduct the test again.

If no improvement is observed, check precisely with
gauges.
G4M0914
3. OPERATION CHECK
1) With engine off, depress brake pedal several times
applying the same pedal force and make sure that the
pedal height does not vary with each depression of the
pedal.
2) With brake pedal depressed, start engine.
3) As engine starts, brake pedal should move slightly
toward the floor. If no change occurs in the pedal height,
brake booster is faulty.
NOTE:
If faulty, check precisely with gauges.
4. LOADED AIR TIGHTNESS CHECK
Depress brake pedal while engine is running, and turn off
engine while the pedal is still depressed. Keep the pedal
depressed for 30 seconds; if no change occurs in the pedal
height, brake booster is functioning normally; if the pedal
height increases, it is faulty.
NOTE:
If faulty, check precisely with gauges.
