Work FlowINFOID:0000000001327957
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions thatexist when the noise occurs. Use the Diag-
nostic Worksheet during the interviewto document t he facts and conditions when the noise occurs and any
customer'scomments; refer to GW-9, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that existwhen the noise occurs.
 The customer may not be able to provide a detailed descriptionor the location of the noise. Attempt to obtain all the facts and conditionsthat exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, be sure to diagnoseand repair the noise that the customer is
concerned about. This can be accomplishedby test driving the vehicle with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fa st movement/broughton by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=l owerpitch noises/edge to surface=chirping
 Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting witha rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration orsimilar movement/loose parts/missing clip
or fastener/incorrect clearance.
 Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/some times repeating/oftenbrought on by driver action.
 Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loosecomponents/can be caused by driver
action or road conditions.
 Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
 Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level will vary dependingupon the person. A noise that you may judge as acceptable may be very irritatingto the customer.
 Weather conditions, especially humidity and temper ature, may havea great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise isduplicated. Note any additional information on
the Diagnostic Worksheet regardingthe conditions or location of the noise. This information can be used to
duplicatethe same conditions when you confirm the repair.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
If the noise can be duplicated easily during the test drive, to helpidentify the source of the noise, try to dupli-
cate the noise with the vehiclestopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears tobe coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-cl utch on M/T models, drive position on 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 conditi ons thecustomer states exist when the noise occurs.
 If it is difficult to duplicate the noise, drive the v ehicle slowlyon an undulating or rough road to stress the vehi-
cle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technica lService Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, fo llow the procedure to repair thenoise.
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: J39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the causeof the noise by:
 removing the components in the area that you suspect the noiseis coming from. Do not use too much force when removing clips and fasteners, otherwiseclips and fastener can be broken or
lost during the repair, resulting in thecreation of new noise.
 tapping or pushing/pulling the component t hat you suspect is causingthe noise.
Do not tap or push/pull the component with excessive force, otherwisethe noise will be eliminated only tem-
porarily.
 feeling for a vibration with your hand by touching t he component(s)that you suspect is (are) causing the
noise.
 placing a piece of paper between components that you suspect arecausing the noise.
 looking for loose components and contact marks. Refer to GW-7, "
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 l oosening and retighteningthe 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 (J43980) is av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plasticand may be damaged.
NOTE:
Always check with the Parts Departm ent for the latest parts information.
The following materials are contained in the Nissan Squeak and Rattle Kit (J43980). Each item can be ordered

conditions as when the noise originallyoccurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingINFOID:0000000001327958
Refer to Table of Contents for specific component removal and installationinformation.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noi se. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolat e a squeak or rattle. If you saturatet he area with silicone, you will not
be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to thecenter console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on startsand stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the ar eas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J43980) to repair the noise.
TRUNK
Trunk noises are often caused by a loose jack or loose items put intothe trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, securing or insulatingthe 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 knockingnoise
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 duplicatingthe conditions can isolate most of these
incidents. Repairs usually consistof insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seatis in and the load placed on the seat when
the noise is present. These conditionsshould be duplic ated 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 suspectedcomponents while duplicating the condi-
tions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
orapplying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or onthe 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.

WINDSHIELD GLASS
CAUTION:
 Never use a cutting knife or power cutting tool when a windshield glass is reused.
 Be careful not to scratch the glass when removing.
 Never set or stand the glass on its edge. Small chips may develop into cracks.
7. Remove the windshield glass, using suction.
INSTALLATION
 Use a genuine Nissan Urethane Adhesive Kit (if available) or equivalent and follow the instructions furnished
with it.
 While the urethane adhesive is curing, open all doors windows. This will prevent the glass from being forced out by passenger room air pressure when all door are closed.
 The molding must be installed securely so that it is in position and leaves no clearance.
 Inform the customer that the vehicle should rema in stationary until the urethane adhesive has completely
cured (approximately 24 hours). Curing time varies with temperature and humidity.
WARNING:
 Keep heat and open flames away as primers and adhesive are flammable.
 The materials contained in the ki t are harmful if swallowed, and may irritate skin and eyes. Never let
them in contact with the skin and eyes.
 Use in an open, well ventilated location. Never br eathe the vapors. They may be harmful if inhaled.
Move immediately to an area with fresh ai r, if affected by vapor inhalation.
 Driving the vehicle before the urethane adhesive has completely cured may affect the performance
of the windshield in case of an accident.
CAUTION:
 Perform adjustment of front wipe r arms stop location. Refer to WW-23, "
Removal and Installation of
Front Wiper Arms, Adjustment of Wiper Arms Stop Location".
 Never use an adhesive which is past its usable term. Shelf life of this product is limited to six months
after the date of manufacture. Adhere carefully to the expiration or manufacture date printed on the
box.
 Keep primers and adhesive in a c ool, dry place. Ideally, they should be stored in a refrigerator.
 Never leave primers or adhesive cartridge un attended with their caps open or off.
 The vehicle should not be driven for at least 24 hours or until the urethane adhesive has completely
cured. Curing time varies depending on temperat ure and humidities. The curing time will increase
under lower temperature and lower humidity.
Repairing Water Leakage for Windshield
Leakage can be repaired without removing glass.
Determine the extent of leakage if water is leaki ng between the urethane adhesive material and body or glass.
This can be done by applying water to the windshield area while pushing glass outward.
Apply primer (if necessary) and then urethane adhesiv e to the leakage point to stop the leakage.
