DUPLICATE THE NOISE AND TEST DRIVE
NGBT0026S0102
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or locations of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
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 (electric load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with rubber hammer.
¼ Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
¼ If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
NGBT0026S0103
After verifying the customer concern or symptom, check ASSIST for Technical Service Bulletins (TSB’s) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
NGBT0026S0104
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis Ear : J-39570, Engine Ear : J-39565 and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
¼ 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.
¼ 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 tem-
porarily.
¼ Feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
¼ Placing a piece of paper between components that you suspect are causing the noise.
¼ Looking for loose components and contact marks.
Refer to Generic Squeak and Rattle Troubleshooting,
REPAIR THE CAUSE
NGBT0026S0105
¼ If the cause is a loose component, tighten the component securely.
¼ If the cause is insufficient clearance between components:
− Separate components by repositioning or loosening and retightening the component, if possible.
− insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts
Department.
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 material are contained in the Nissan Squeak and Rattle Kit (J-43980) Each item can be ordered
separately as needed.

68370–4B000 : 15 x 25mm pad / 68239–13E00 : 5mm wide tape roll
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW (TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note : Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
NGBT0026S0106
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.

NGBT0026S02
INSTRUMENT PANEL
NGBT0026S0201
Most incidents are caused by contact and movement between :
1. The 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 harness 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 noise. 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 isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
NGBT0026S0202
Components to pay attention to include :
1. Shifter assembly cover to finisher.
2. A/C control unit and cluster lid C
3. Wiring harness behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to center console.
DOORS
NGBT0026S0203
Pay attention to the :
1. Finisher an 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 starts and 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 areas with felt cloth or insulator foam blocks from the
Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

TRUNK
NGBT0026S0204
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 bumpers 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
Most of these incidents can be repaired by adjusting, securing, or insulating the items(s) or components(s)
causing the noise.
SUNROOF AND HEADLINER
NGBT0026S0205
Noises in the sunroof and headliner 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 headliner 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
NGBT0026S0206
When isolating seat noises it’s important to note the position the seat 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 holders
2. A squeak between the seat pad cushion and frame
3. The rear seat back 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
NGBT0026S0207
Some interior noises 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 noises include:
1. Any components 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 can not 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.
Repair can usually be made by moving, adjusting, securing, or insulating the component causing the noise.

Removal and Installation
NGBT0004
¼ When removing or installing hood, place a cloth or other padding on hood. This prevents vehicle body from
being scratched.
¼ Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
¼ Hood adjustment: Adjust at hinge portion.
¼ Hood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
¼ Hood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.
