CUSTOMER INTERVIEW
Interview the customer if possible, to determine the c onditions 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
customer comments. Refer to EXT-10, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by per forming a test drive with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so that the customer, service advis er, and technician use the same language when describing
the noise.
 Squeak – (Like tennis shoes on a clean floor) Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard sur-
faces = high-pitched noise / softer surfaces = low-pitched 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 fast repeated contact / vibr ation or similar movement / loose parts/missing clip
or fastener / incorrect clearance.
 Knock – (Like a knock on a door) Knock characteristics include hollow sounds / someti mes repeating / often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise)
Thump characteristics include softer knock / dull sounds often brought on by activity.
 Buzz – (Like a bumblebee) Buzz characteristics include high frequency rattle / firm contact.
 Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may
judge as acceptable may be very irritating to a customer.
 Weather conditions, especially humidity and temperat ure, 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 lo cation of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.
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 items:
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-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 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, che ck ASIST for Technical Service Bulletins (TSBs) related
to the 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, and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
 Removing the component(s) in the area that is / are suspected to be the cause of the noise.
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(s) that is / are suspected to be the cause of the noise.
Do not tap or push/pull the component(s) with excessive force, otherwise the noise is eliminated only tempo-
rarily.
 Feeling for a vibration by hand by touching the component(s ) that is / are suspected to be the cause of the
noise.
 Placing a piece of paper between components that are suspected to be the cause of the noise.
 Looking for loose components and contact marks. Refer to EXT-8, "
Inspection Procedure".
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 components, 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 the authorized NISSAN Parts
Department.
CAUTION:
Never use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSA N Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.
