WORK FLOW
Customer Interview
Interview the costumer, if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customers comments; refer to
. This information is necessary to duplicate
the conditions that exist when the noise occurs.
●
The customer may not be able to provide a detail description or location of the noise. Attempt to obtain all
the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by 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 / fast movement / brought on by road conditions / hard
surfaces = higher pitch noise / softer surfaces = lower pitch noises / edge to surface = chirping.
–
Creak-(Like walking on an old wooden floor)
•
Creak characteristics include firm contact / slow movement / twisting with a rotational movement / pitch
dependent on materials / often brought on by activity.
–
Rattle-(Like shaking a baby rattle)
•
Rattle characteristics include the fast repeated contact / vibration or similar movement / loose parts / miss-
ing clip or fastener / incorrect clearance.
–
Knock-(Like a knock on a door)
•
Knock characteristics include hollow sound / something repeating / often brought on by driver action.
–
Tick-(Like a clock second hand)
•
Tick characteristics include light contact of light material / loose components / can be caused by driver
action on road conditions.
–
Thump-(Heavy, muffled knock noise)
•
Thump characteristics include softer knock / 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 depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.
Duplicate the Noise and Test Drive
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.
●
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 vehicle slowly on an undulating or rough road to stress the
vehicle body.
Check Related Service Bulletins
After verifying the customer concern or symptom, check ASSIST for Technical Service Bulletins (TSBs)
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
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:
●
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 bro-
ken 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 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 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.
●
URETHANE PADS (1.5 mm thick)
–
insulates connectors, harness, etc.

Confirm the Repair
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.
GENERIC SQUEAK AND RATTLE TROUBLESHOOTING
Instrument Panel
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 silicone 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
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
4.
Console lid to console bin.
The instrument panel repair and isolation procedures also apply to center console.
Doors
Pay attention to the:
1.
Finisher an inner panel making a slapping noise
