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

Refer to RFD-16, "Components" about each tightening torque.

When installing breather hoses, refer to the figure and following.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–For installation of rear final drive breather hose, the vehicle side
end shall be inserted to cross member. Install metal connector
side of this hose to rear cover by inserting it with aiming painted
marking to the front of vehicle.
–For installation of electric controlled coupling breather hose, the
vehicle side end shall be inserted to cross member. Install its
metal tube to rear final drive assembly and direct the metal tube
hose side end to the front of vehicle.

When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to RFD-8, "
Checking Differential
Gear Oil" .

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionEES0006Z

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.

After installing the removed suspension parts, always check wheel alignment and adjust if necessary.

Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

BRAKE FLUID

BRAKE FLUIDPFP:KN100
Checking Brake Fluid Level EFS000C5

Confirm reservoir tank fluid level is within the specifications
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Always keep fluid level higher than minimum line on reservoir tank.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away water immediately.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while
depressing brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

PRECAUTIONS

[ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS005X6
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemEFS004GX

Recommended fluid is brake fluid “DOT 3” or “DOT 4”.

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut torque wrench, securely tighten brake tube
flare nuts.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect har-
ness connectors of ABS actuator and electric unit (control unit)
or battery cable from negative terminal.

When installing brake piping, be sure to check torque.
Precautions for Brake ControlEFS004FV

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an malfunction is indicated by ABS or another warning lamp, collect all necessary information from
customer (what symptoms are present under what conditions) and check for simple causes before start-
ing diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level,
and oil leaks.

If tyre size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction.

If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

Precautions for Brake SystemEFS0019O

Recommended fluid is brake fluid “DOT 3” or “DOT 4”.

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of hydraulic system.

Using a flare nut torque wrench, securely tighten brake tube
flare nuts.

When installing brake piping, be sure to check torque.

Before working, turn the ignition switch OFF and disconnect the
connectors for the ESP/TCS/ABS control unit and control unit or
the battery negative terminal.

Burnish the brake pad contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or linings, or if a
soft pedal occurs at very low mileage. Refer to BR-31, "
BRAKE
BURNISHING PROCEDURE" .
WARNING:
Clean brakes with a vacuum dust collector to minimize risk of health hazard from powder caused
by friction.
Precautions for Brake ControlEFS0019P

During the ESP/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be
heard. This is a normal condition.

Just after starting the vehicle after ignition switch ON, the brake pedal may vibrate or the motor operating
noise may be heard from the engine compartment. This is a normal status of the operation check.

The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough,
gravel, or snowy (fresh deep snow) road.

If a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary infor-
mation from the customer (what symptoms are present under what conditions) and find out the possible
causes before starting the service. Besides the electrical system inspection, check the booster operation,
brake fluid level, and oil leaks.

If the tyre size and type are used in a improper combination, or the brake pads are not NISSAN genuine
parts, the stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ESP/TCS/
ABS function may have a malfunction.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check harnesses for pinches, open,
and improper wiring.
