CUSTOMER INTERVIEW
Interview the customer, if possible, to determine the conditions that exis t 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 EI-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, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by te st 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 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 bumblebee) 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 SBT842

EI
N
O P
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.
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:
• Close a door.
• Tap or push/pull around the area where the noise appears to be coming from.
• Rev the engine.
• Use a floor jack to recreate vehicle “twist”.
• At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T and CVT models).
• 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 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 pi npoint 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 broken 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 excessi ve force, otherwise the noise will be elimi-
nated only temporarily.
• Feeling for a vibration with your hand by touching t he 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 EI-8, " 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 materials are contained in the NISSA N Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.
URETHANE PADS [1.5 mm (0.059 in) thick]
Insulates connectors, harness, etc.
76268-9E005: 100 x 135 mm (3.94 x 5.31 in)/76884-71L01: 60 x 85 mm (2.36 x 3.35 in)/76884-71L02: 15 x 25
mm (0.59 x 0.98 in)
INSULATOR (Foam blocks)
Insulates components from contact. Can be used to fill space behind a panel.
73982-9E000: 45 mm (1.77 in) thick, 50 x 50 mm (1.97 x 1.97 in)/73982-50Y00: 10 mm (0.39 in) thick, 50 x 50
mm (1.97 x 1.97 in)
INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30 x 50 mm (1.18 x 1.97 in)

3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, se curing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
OVERHEAD CONSOLE (FRONT AND REAR) Overhead console noises are often caused by the cons ole panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the c onsole at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplic ated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed on the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs c an usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.
Precaution for Liquid Gasket INFOID:0000000004784266
REMOVAL OF LIQUID GASKET SEALING
• After removing the bolts and nuts, separate the mating surface and remove the sealant using Tool.
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to
lightly tap (1) the cutter where the RTV Silicone Sealant is applied.
Use a plastic hammer to slide the cutter (2) by tapping on the side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old Silicone RTV Sealant adhering to the gasket application surface and the mating surface.
• Remove the sealant completely from the groove of the gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the sealant t ube to the tube presser.
Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-42, " Recommended Chemical
Product and Sealant " .
4. Apply the sealant without breaks to the specified location using Tool.
• If there is a groove for the s ealant application, apply the seal-
ant to the groove.
• As for the bolt holes, normally apply the sealant inside the holes. If specified, it should be applied outside the holes. Make
sure to read the text of this manual.
• Within five minutes of the seal ant application, install the mat-
ing component.
• If the sealant protrudes, wipe it off immediately.
• Do not retighten after the installation. Tool number : KV10112100 (BT-8653-A)
