Work Flow

INFOID:0000000012196876

CUSTOMER INTERVIEW

Interview the customer 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 of

customer's comments; refer to 

SE-15, "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 when 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 performing a cruise test on 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 depen-

dent 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/missing

clip or fastener/incorrect clearance.

• Knock – (Like a knock on a door)

Knock characteristics include hollow sounding/sometimes 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/dead sound often brought on by activity.

• Buzz – (Like a bumblebee)

Buzz characteristics include high frequency rattle/firm contact.

• Often the degree of acceptable noise level will vary depending up on the person. A noise that a technician

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

SBT842

< SYMPTOM DIAGNOSIS >

SQUEAK AND RATTLE TROUBLE DIAGNOSES

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 location 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:

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 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, check ASIST 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 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 is are suspected to be the cause of the noise.

Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken

or lost during the repair, resulting in the creation of new noise.

• Tapping or pushing/pulling the component that is are suspected to be the cause of the noise.

Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only tem-

porarily.

• 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 

SE-13, "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 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-50397) 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.
