SQUEAK AND RATTLE TROUBLE DIAGNOSES
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on CVT and A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
• Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
• If it is difficult to duplicate the noise, drive the v ehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, chec k ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follo w the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pi npoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
• removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be
broken or lost during the repair, resulting in the creation of new noise.
• tapping or pushing/pulling the component that you suspect is causing the noise. Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
• feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
• placing a piece of paper between components that you suspect are causing the noise.
• looking for loose components and contact marks. Refer to RF-37, "Generic Squeak and Rattle Troubleshooting"
.
REPAIR THE CAUSE
• If the cause is a loose component, tighten the component securely.
• If the cause is insufficient clearance between components:
- separate components by repositioning or loos ening and retightening the component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane
tape. A NISSAN Squeak and Rattle Kit (J-43980) is av ailable through your authorized NISSAN Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISS AN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

< SYMPTOM DIAGNOSIS >
SQUEAK AND RATTLE TROUBLE DIAGNOSES
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 c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor 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.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the c onsole panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the c onsole at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be dupl icated 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. The 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 thes e 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 installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation 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.

AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies in cluding retractors and attaching hardware after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced
unless the collision was minor and th e belts show no damage and continue to operate properly. Fail-
ure to do so could result in serious personal inju ry in an accident. Seat belt assemblies not in use dur-
ing a collision should also be replaced if either da mage or improper operation is noted. Seat belt pre-
tensioners should be replaced even if the seat belts are not in use during a frontal collision in which
the air bags are deployed.
Replace any seat belt assembly (including anchor bolts) if:
• The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
• The seat belt was damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).
• The seat belt attaching point is damaged in an accident . Inspect the seat belt attaching area for damage or
distortion and repair if necessary before installing a new seat belt assembly.
• Anchor bolts are deformed or worn out.
• The seat belt pre-tensioner should be replaced even if t he seat belts are not in use during the collision in
which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp for proper operation per the following:
a. Turn ignition switch ON. The seat belt warning lamp should illuminate.
b. Fasten driver seat belt. The seat belt warning lamp should turn OFF.
2. If the air bag warning lamp is blinking, perform self-diagnosis with CONSULT and air bag warning lamp. Refer to SRC-17, "Trouble Diagnosis without CONSULT"
.
3. Check that the seat belt retractor, seat belt anchor and buckle bolts are tightened firmly.
4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Check that guide
swivels freely and that webbing lays flat and does not bind in guide. Check that height adjuster operates
properly and holds securely.
5. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Check that webbing retu rns smoothly and completely into the retractor. If the
seat belt does not return smoothly, wipe the inside of t he loops with a clean paper cloth. Dirt build-up in the
loops of the upper anchors can cause t he seat belts to retract slowly.
c. Fasten the seat belt. Check that seat belt returns sm oothly and completely to the retractor. If the webbing
does not return smoothly, the cause may be an accu mulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
d. Inspect the front seat belt D-ring anchor 1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Hold the seat belt at the center pillar webbing opening with a clip or other device.
3. Pass a thin wire through the D-ring anchor webbing opening. Hold both ends of the wire and pull it tightly while moving it up and down several times along the webbing opening surface to remove dirt
stuck there.
4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the webbing contacts the D-ring anchor webbing opening. NOTE:
Apply the tape so that there is no slack or wrinkling.
6. Remove the clip holding the seat belt and check that the webbing returns smoothly.
6. Repeat steps above if necessary to check the other seat belts.
