Precaution for Servicing Rear Final DriveINFOID:0000000001604452
• Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
• Check for the correct installation status prior to re moval or disassembly. When matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
• Overhaul should be done in a clean work area, a dust proof area is recommended.
• Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
• Always use shop paper for cleaning the inside of components.
• Avoid using cotton gloves or a shop cloth to prevent the entering of lint.
• Check appearance of the disassembled parts for dam age, deformation, and abnormal wear. Replace them
with new ones if necessary.
• Gaskets, seals and O-rings should be replaced any time the unit is disassembled.
• Clean and flush the parts sufficiently and blow them dry.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil, and
foreign materials from the application and mating surfaces.
• In principle, tighten nuts or bolts gradually in severa l steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.
• During assembly, observe the specified tightening torque.
• Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.

Precaution for Liquid GasketINFOID:0000000001538800
REMOVAL OF LIQUID GASKET SEALING
• After removing the bolts and nuts, separate the mating surface and
remove the old liquid gasket sealing using Tool.
CAUTION:
Do not damage the mating surfaces.
• Tap the seal cutter to insert it (1).
• In areas where the Tool is difficult to use, lightly tap to slide it (2).
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface using suitable tool.
• Remove the liquid gasket completely from the groove of the
liquid gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign material.
3. Attach the liquid gasket tube to the Tool. Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-15, "
Recommended Chemical Products and Sealants".
4. Apply the liquid gasket without breaks to the specified location with the specified dimensions.
• If there is a groove for the liquid gasket application, apply theliquid gasket to the groove.
• As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified in the procedure, it should also be
applied outside the holes.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• Wait 30 minutes or more after installation before refilling the engine with engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

INTAKE MANIFOLD
• Tighten the intake manifold bolts in numerical order as shown.
• Install the EVAP canister purge control solenoid valve connector with it facing front of engine.
• Tighten the electronic throttle control actuator bolts of the electric throttle control actuator equally and diago-
nally in several steps.
• After installation perform procedure in "INSPECTION AFTER INSTALLATION".
• Install the water hose so that its overlap width for connection is between 27 mm (1.06 in) and 32 mm (1.26 in) (target: 27 mm 1.06 in).
Connecting Quick Connector of Fuel Tube
Install quick connector as follows (the steps are t he same for quick connectors on both engine side and vehi-
cle side except for the quick connector cap).
1. Make sure no foreign substances are deposited in and around tube and quick connector, and they are not damaged.
2. Thinly apply new engine oil around the fuel tube from tip end to the spool end.
3. Align center to insert quick connector straight into fuel tube. • Insert until the paint mark for engagement identification (white)goes completely inside quick connector so that you cannot see
it from the straight side of the connected part. Use a mirror to
check this where it is not possible to view directly from the
straight side, such as quick connector on vehicle side.
• Insert fuel tube into quick connector until top spool is com- pletely inside quick connector, and 2nd level spool exposes
right below quick connector on engine side.
CAUTION:
• Hold "A" position in illustration when inserting fuel tubeinto quick connector.
• Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
• Insert until you hear a "click" sound and actually feel the
engagement.
• To avoid misidentification of engagement with a similar
sound, be sure to pe rform the next step.
4. Pull quick connector by hand holding "A" position. Make sure it is completely engaged (connected) so that
it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
