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
customer comments. Refer to 

RF-30, "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 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 adviser, 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 / vibration or similar movement / loose parts/missing clip
or fastener / incorrect clearance.

• Knock – (Like a knock on a door)

Knock characteristics include hollow sounds / 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 / 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 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 location of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.
