TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

SUNROOF

3. Remove guide plate.
4. Remove drain channel.
5. Rotate link of wire assembly, then push link or slider to backward of vehicle.
6. Remove link assembly and wire assembly from sunroof unit assembly.
CAUTION:
Do not disconnect link assembly and wire assembly.
Installation
Install in the reverse order of removal.

On-Vehicle Inspection BES00040
Make sure that the mounting conditions (looseness, back lash) of each components and component status
(wear, damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by placing an iron pry bar or a similar item between suspension arm and axle housing
prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage installation position by applying excessive
force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES00041
DESCRIPTION
Measure the wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” mean that fuel, engine coolant, and lubricant are full. A spare tire, a 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. Refer to WT-3, "
ROAD WHEEL" .
3. Check wheel bearing axial end play. Refer to RAX-3, "
WHEEL BEARING INSPECTION" .
4. Check suspension arm ball joint axial end play. Refer to RSU-11, "
Ball Joint Inspection" .
5. Check shock absorber operation.
6. Check each mounting point of axle housing and suspension for looseness and deformation.
7. Check each link, arm, and member for cracks, deformation, and other damage.
8. Check vehicle height (posture).
CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable
alignment gauge.

Adjust in accordance with the following procedures.

If camber is not within the specification, adjust by turning the
adjusting bolt of front lower link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "

REAR SUSPENSION ASSEMBLY

TOE-IN
Measure toe-in using following procedure. If out of the specification, inspect and replace any damaged or worn
rear suspension parts.
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 rear of vehicle up and down to stabilize the vehicle
height 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 the wheels have rotated more than 180 degrees (1/2 turn),
start this procedure again from the beginning. Do not push the
vehicle backward.
6. Measure distance “B” (front side).
7. If toe-in is not within the specification, adjust by turning the
adjusting bolt of rear lower link.
CAUTION:
When adjusting toe-in, set the both sides to the same val-
ues.

InspectionBHS0003T
INSPECTION AFTER ACCIDENT
After a collision, inspect for damage or distortion of retractor, seat belt anchor, floor anchor, or shoulder
anchor. Nissan recommends replacement of all seat belt assemblies in the following cases because these
impairments may lead to personal injury.

After a collision

When installation point of seat belt assembly on vehicle is damaged.

When it does not operate normally.
INSPECTION FOR SEAT BELT RETRACTOR
1. Using seat belt warning lamp, make sure that it works normally.
NOTE:
When ignition is turned ON and driver seat belt is not in use, seat belt warning lamp is turned on. It is
turned off when driver seat belt is in use.
2. Check whether anchor bolts on seat belt retractor and buckle are securely tightened.
3. Check if seat belt shoulder anchor rotates freely and seat belt adjuster operates properly.
4. Retractor operation inspection
a. Pull out all webbing and check for twisting, cuts, or other damage.
b. Retract webbing. Check if the webbing is retracted smoothly and completely into the retractor. When web-
bing is not retracted smoothly due to dust or other reasons, perform the following procedure with “SEAT
BELT, TAPE SET”.
Inspection for Front Seat Belt Shoulder Anchor
1. Pull webbing out 50 cm or more.
2. Fix webbing near the belt exit with a clip.
3. Pass a thin wire into the through part of shoulder anchor and webbing. Remove the materials that are
stuck from the webbing by sliding the wire vertically along the surface of the webbing through part while
pulling both sides of wire tightly.
4. Clean the remaining dirt by cleaning the webbing through part with a clean cloth.
5. Apply tape to the shoulder anchor belt through part where webbing touches.
NOTE:
Be careful to apply tape with no wrinkling or looseness.

CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Remove the cell plug using a suitable tool.

Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Convert into specific gravity at 20°C (68°F).
Example:

When electrolyte temperature is 35°C (95°F) and specific gravity
of electrolyte is 1.230, converted specific gravity at 20°C (68°F)
is 1.240.

When electrolyte temperature is 0°C (32°F) and specific gravity
of electrolyte is 1.210, converted specific gravity at 20°C (68°F)
is 1.196.

MOVEMENT (QR20DE MODELS)

Compare movement “L” in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by
hand until it touches stopper.

Not in the specified value... Adjust by adjusting plate.Clearance “L” : Refer to SDS. SC-38, "
