INSTALLATION
Note the following, and installation is in the reverse order of removal.

Refer to FFD-13, "COMPONENTS" about each tightening torque.

When installing the side shaft, apply multi-purpose grease to contact surface of side shaft and side shaft
oil seal.

Tighten mounting bolts in the order as described below when
installing front final drive assembly: side of gear carrier (1),
upper side of gear carrier (2), part of carrier cover (3), lower part
of gear carrier (4).
CAUTION:
Align the mating faces of gear carrier and oil pan for instal-
lation.

When installing breather hoses (1) and tube (2), refer to the fig-
ure.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–Make sure the paint mark facing up ( ).
–Securely install the hose until it seats the rounded portion of the
tube ( ).
–Install breather connector as shown in the figure.
–Seat the breather tube bracket end (A) to the machined face (B)
of gear carrier boss.

When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to FFD-8, "

Checking Fuel LinesNBS005R8
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsNBS005R9
WARNING:
When replacing fuel line parts, be sure to observe the following.

Put a “CAUTION: FLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:

Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Premium Gasoline Required) (VK45DE Engine Models)" .

Before removing fuel line parts, perform out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-88, "FUEL PRESSURE RELEASE" (VQ35DE)
or EC-790, "
FUEL PRESSURE RELEASE" (VK45DE).
–Disconnect the battery cable from the negative terminal.

Always replace O-ring and clamps with new ones.

Do not kink or twist tubes when they are being installed.

Do not tighten hose clamps excessively to avoid damaging hoses.

After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.

After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.

Use only a genuine NISSAN fuel filler cap as a replacement.
If an incorrect fuel filler cap is used, the “MIL” may come
on.

For servicing “Evaporative Emission System” parts, refer to
EC-39, "
EVAPORATIVE EMISSION SYSTEM" (VQ35DE) or
EC-741, "
EVAPORATIVE EMISSION SYSTEM" (VK45DE).

For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-46, "
ON BOARD REFUELING VAPOR
RECOVERY (ORVR)" (VQ35DE) or EC-748, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" (VK45DE).
