WARNING:

Read “General Precautions” before working on the fuel system. Refer to 

FL-3, "General Precautions"

 .

1.

Check fuel level on level place. If gauge indicates more than the
level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.

●

In case fuel pump does not operate, take following procedure.

a.

Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel
filler tube through fuel filler opening to draw fuel from fuel filler
tube.

b.

Disconnect fuel filler hose from fuel filler tube.

c.

Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.

●

As a guide, fuel level becomes the position shown in figure or
below when approximately 20 liter (5-1/4 US gal, 4-3/8 Imp gal) of fuel are drained from fuel tank. 

2.

Release the fuel pressure from the fuel lines. Refer to 

EC-66, "FUEL PRESSURE RELEASE"

 .

3.

Open the fuel filler lid.

4.

Open the filler cap and release the pressure inside the fuel tank.

5.

Remove the rear seat cushion trim and pad bolts, then lift up rear seat cushion. Refer to 

SE-129, "REAR

6.

Remove the inspection hole cover for main and sub fuel level
sensor unit by turning clips counterclockwise by 90

°

.

7.

Disconnect the harness connector and quick connectors for
EVAP/Vent line hose and fuel feed tube

●

Disconnect EVAP/Vent line hose connector (push in tubs and
pull out).

●

Disconnect the quick connector for fuel feed tube as follows:

CAUTION:

●

The quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than nec-
essary.

●

Do not use any tools to disconnect the quick connector.

●

Keep the resin tube away from heat. Be especially careful
when welding near the tube.

●

Prevent acid liquid such as battery electrolyte etc. from
getting on the resin tube.

●

Do not bend or twist the resin tube during installation and
disconnection.

●

Do not remove the remaining retainer on the hard tube (or
the equivalent) except when the resin tube or the retainer
is replaced.

●

When the resin tube or hard tube (or the equivalent) is
replaced, also replace the retainer with a new one.

PRECAUTIONS

Revision; 2004 April

PRECAUTIONS

PFP:00001

Caution

AES000G7

●

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

●

Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

●

After servicing suspension parts, be sure to check wheel alignment.

●

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

FRONT SUSPENSION ASSEMBLY

PFP:54010

On-Vehicle Inspection and Service

AES000GB

Make sure the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.

INSPECTION OF TRANSVERSE LINK END PLAY

1.

Set front wheels in a straight-ahead position. Do not depress brake pedal.

2.

Measure axial end play of transverse link ball joint by prying between suspension arm and front axle with
a iron bar or something similar.

CAUTION:

Be careful not to damage ball joint boot.

STRUT INSPECTION

Check strut for oil leakage, damage and replace if necessary.

Wheel Alignment Inspection

AES000GC

DESCRIPTION

●

Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, engine cool-
ant, and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.

PRELIMINARY CHECK

1.

Check tires for improper air pressure and wear.

2.

Check road wheels for runout.

3.

Check wheel bearing axial end play.

4.

Check transverse link ball joint axial end play.

5.

Check strut operation.

6.

Check each mounting point of axle and suspension for looseness and deformation.

7.

Check each link, rod, and member for cracks, deformation and other damage.

8.

Check vehicle posture.

INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

●

Camber, caster, kingpin inclination angles cannot be adjusted.

●

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.

Using a CCK Gauge

1.

Remove wheel nuts (3), and install a guide bolt (SST) to hub
bolt.

2.

Screw adapter (SST) into plate body (SST) until it contacts body
tightly.

3.

Screw center plate (SST) into plate body (SST).

4.

Insert plate (SST) on guide bolt (SST). Put spring in, and then
evenly screw in guide bolt nut (SST). When fastening guide bolt
nut, do not completely compress spring.

FRONT SUSPENSION ASSEMBLY

Revision; 2004 April

2003 Murano

5.

Place the dent of alignment gauge onto the projection of center
plate (SST) and tightly contact them to measure.

CAUTION:

●

If camber, caster, or kingpin inclination angle is outside
the standard, check front suspension parts for wear and
damage, and replace suspect parts if necessary.

●

Kingpin inclination angle is reference value, no inspec-
tion is required. (Due to the type of suspension, the king-
pin inclination angle cannot be measured correctly using a normal alignment tester.)

Toe-In Inspection

Measure toe-in using the following procedure.

WARNING:

●

Always perform the following procedure on a flat surface.

●

Make sure that no person is in front of vehicle before push-
ing it.

1.

Bounce front of vehicle up and down to stabilize the posture.

2.

Push vehicle straight ahead about 5 m (16 ft).

3.

Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.

4.

Measure distance “A” (rear side).

5.

Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).

If wheels have rotated more than 180 degrees (1/2 turn), try the
