CAUTION:
When working with FIPG material, you must observe the follow-
ing items.

Using a razor blade and gasket scraper, remove all the old
FIPG material from the gasket surfaces.

Thoroughly clean all components to remove all the loose
material.

Clean both sealing surfaces with a non±residue solvent.

Apply FIPG in an approx. 1 mm (0.04 in.) wide bead along
the sealing surface.

Parts must be assembled within 10 minutes of application.
Otherwise, the FIPG material must be removed and reap-
plied.
1. REMOVE DRAIN PLUG WITH GASKET AND DRAIN

2. REMOVE OIL PAN
NOTICE:
Some fluid will remain in the oil pan.
(a) Remove the 19 bolts.
(b) Install the blade of SST between the transmission case
and oil pan, cut off applied sealer, and remove the oil pan.
SST 09032±00100
NOTICE:
When removing the oil pan, be careful not to damage the oil
pan flange.
3. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect steel particles.
Carefully look at the foreign matter and particles in the pan and
on the magnets to anticipate the type of wear you will find in the
transmission.
Steel (magnetic) ... bearing, gear and clutch plate wear
Brass (non±magnetic) ... bushing wear

8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe these procedures:
(1) Union Bolt Type:
Always use a new gasket.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to the specified
torque.
SST 09631±22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque:
30 N´m (310 kgf´cm, 22 ft´lbf) for using SST
38 N´m (387 kgf´cm, 28 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

(c) Observe these precautions when removing and installing
the injectors.
(1) Never reuse the O±ring.
(2) When placing a new O±ring on the injector, take
care not to damage it in any way.
(3) Coat a new O±ring with spindle oil or gasoline be-
fore installing±never use engine, gear or brake oil.
(d) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
Before installing the injector, must apply spindle oil or gas-
oline on the place where a delivery pipe or an intake man-
ifold touches an O±ring of the injector.
(e) Observe these precautions when disconnecting the fuel
tube connector (quick type):
(1) Check if there is any dirt like mud on the pipe and
around the connector before disconnecting them
and clean the dirt away.
(2) Be sure to disconnect with hands.
(3) When the connector and the pipe are stuck, push
and pull the connector to free to disconnect and pull
it out. Do not use any tool at this time.
(4) Inspect if there is any dirt or the likes on the seal sur-
face of the disconnected pipe and clean it away.
(5) Prevent the disconnected pipe and connector from
damaging and mixing foreign objects by covering
them with a vinyl bag.
(f) Observe these precautions when connecting the fuel
tube connector (quick type):
(1) Check if there is any damage or foreign objects on
the connected part of the pipe.
(2) Match the axis of the connector with axis of the pipe,
and push in the connector until the connector
makes a ºclickº sound. In case the connections is
tight, apply little amount of new engine oil on the tip
of the pipe.

3. INSPECT WHEEL BALANCE
(a) Check and adjust the off±the±car balance.
(b) If necessary, check and adjust the on±the±car balance.
Unbalance after adjustment: 8.0 g (0.018 lb) or less
NOTICE:

Adhere the sticking type balance weight to the flat
position shown in the illustration.

Push the balance weight securely with a finger to ad-
here it to the position.
(Pushing force: 10 kgf/more than 2 secs.)

After cleaning the surface which the balance weight
will be adhered to of dirt, oil and water with a cleaning
detergent, adhere the balance weight to the surface.

Do not touch the sticking surface of the tape.

Do not use the once used balance weight.

Please use the TOYOTA genuine sticking type bal-
ance weight.
4. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in the bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
5. CHECK FRONT SUSPENSION FOR LOOSENESS
6. CHECK STEERING LINKAGE FOR LOOSENESS
7. CHECK BALL JOINT FOR LOOSENESS AND
EXCESSIVE PLAY (See page SA±34)
8. CHECK SHOCK ABSORBER WORKS PROPERLY

Check for oil leak

Check mounting bushings for wear

Bounce front and rear of the vehicle

6. INSTALL DRIVE PINION BEARING OUTER RACES
AND ADJUSTING WASHER
HINT:

The adjusting washer is used for adjusting the tooth con-
tact pattern. 42 types of washer with different thicknesses
are available.

First fit a washer with the same thickness as the washer
which was removed, then after checking the tooth contact
pattern, replace the washer with one of a different thick-
ness if necessary.

When removing an adjusting washer, be sure to replace
it with a new one.
(a) Using SST and a press, install the front bearing outer
race.
SST 09950±60020 (09951±00710),
09950±70010 (09951±07150)
(b) Using SST and a press, install a new adjusting washer to
the rear bearing outer race.

8. TEMPORARILY INSTALL DRIVE PINION, FRONT
BEARING, OIL SLINGER AND COMPANION FLANGE
(a) Install the drive pinion in the differential carrier.
(b) Using SST and a press, install the front bearing on the
drive pinion.
