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's comments; refer to RF-44, "
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, 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/fa st movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=l ower pitch noises/edge to surface=chirping
• Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/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 contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/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 k nock/dead sound often brought on by activity.
• Buzz—(Like a bumble bee)
Buzz characteristics include hi gh 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 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 you confirm the repair.
