SQUEAK AND RATTLE TROUBLE DIAGNOSES
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 model, drive position on A/T model).
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 (TSB) 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
(Engine Ear or 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 tem-
porarily.
 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 XX-XX, "*****"
.
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 urethane
tape are 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:
 URETHANE PADS
Insulates connectors, harness, etc.
 INSULATOR (Foam blocks)
Insulates components from contact. Can be used to fill space behind a panel.
 INSULATOR (Light foam block)
 FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
The following materials, not available through NISSAN Parts Department, can also be used to repair
squeaks and rattles.
 UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
 SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
 SILICONE SPRAY
Use when grease cannot be applied.
 DUCT TAPE
Use to eliminate movement.

5. Remove hood opener on bottom left of instrument panel, and
then remove hood lock cable.
6. Remove grommet on lower dashboard, and pull out hood lock
cable from passenger room side.
CAUTION:
While pulling the cable, be careful not to damage (peel)
hood opener cable outer surface on edges of body through
hole.
INSTALLATION
Installation is in the reverse order of removal.
 Perform hood fitting adjustment. Refer to DLK-583, "
Fitting Adjustment".
Hood Lock Reinforcement
When installing hood lock reinforcement, loosen hood bolts, and
then tighten bolts in the order as shown.
Hood Lock Cable
1. Pull the hood lock cable through the panel hole to the engine compartment.
CAUTION:
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 around the grommet (at * mark).
4. Install cable securely to lock.
5. After installing, check hood lock adjustment and hood opener
operation.
Hood Lock Control InspectionINFOID:0000000001732038
CAUTION:
If the hood lock cable is bent or deformed, replace it.
