SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2006 November2007 350Z
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 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:
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 you suspect the noise is coming from.
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 you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.

feeling for a vibration with your hand by touching the 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 BL-9, "
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.
NOTE:
Always check with the Parts Department for the latest parts information.
The following materials are contained in the Nissan 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: 100×135 mm (3.94×5.31 in)/76884-71L01: 60×85 mm (2.36×3.35 in)/76884-
71L02: 15×25 mm (0.59×0.98 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, 50×50 mm (1.97×1.97 in)/73982-50Y00:
10 mm (0.39 in) thick, 50×50 mm (1.97×1.97 in)

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2006 November2007 350Z
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing 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. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining 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.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated 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 these 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 mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting 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 can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

HOOD
Revision: 2006 November2007 350Z
SURFACE HEIGHT ADJUSTMENT
1. Remove hood lock assembly, and adjust the surface height difference of hood and fender according to the
fitting standard dimension, by rotating RH and LH bumper rubbers.
2. Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.
3. Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.
4. Make sure that the hood lock primary latch is securely engaged
with the hood striker with hood's own weight by dropping hood
from approx. 200 mm (7.87 in) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
5. Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.
6. When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch
is disengaged. Also make sure that hood opener returns to the original position.
7. After adjustment, tighten lock bolts to the specified torque.
CAUTION:
Adjust evenness between hood and fender to the following specification.
Hood and fender (C–C) : 0 ± 1.0 mm (0 ± 0.04 in)

5. While pulling the hood lock cable, remove hood lock cable con-
nected to hood opener handle.
6. Remove grommet on dash board, and pull hood lock cable
toward passenger compartment.
CAUTION:
While pulling, be careful not to damage (peeling) the outside of
the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine compartment.
Be careful not to bend the cable too much, keeping the radius
100 mm (3.94 in) or more.
2. Check that the cable is not offset from the positioning grommet,
and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install while pulling hood lock cable.
5. Install the hood lock cable securely to the hood lock.
6. Install hood lock assembly.
7. After installing, check the hood lock adjustment and hood
opener operation.
Hood Lock Control InspectionNIS0000D
CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Check that the secondary latch is properly engaged with the
secondary striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height.
2. While operating the hood opener, carefully check that the front
end of the hood is raised by approx. 20 mm (0.79 in). Also check
that the hood opener returns to the original position.
