SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2006 December 2006 FX35/FX45
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 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 (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 EI-7, "
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.

4. Remove fuel feed hose (with damper) from fuel sub-tube. NOTE:
There is no fuel return route.
CAUTION:

While hoses are disconnected, plug them to prevent fuel
from draining.

Do not separate damper and hose.

a. Remove quick connector cap from quick connector connection on right member side.
b. Disconnect fuel feed hose (with damper) from bracket hose clamp.
c. Disconnect quick connector from centralized under-floor piping as follows: CAUTION:
Disconnect quick connector by using quick connector release [SST: — (J-45488)], not by picking
out retainer tabs.
i. With the sleeve side of quick connector release facing quick connector, install quick connector release onto centralized under-floor piping.
ii. Insert quick connector release into quick connector until sleeve contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
iii. Draw and pull out quick connector straight from centralized under-floor piping.
CAUTION:

Pull quick connector holding “A” position as shown in
the figure.

Do not pull with lateral force applied. O-ring inside quick connector may be damaged.

Prepare container and cloth beforehand as fuel will leak out.

Avoid fire and sparks.

Keep parts away from heat source. Especially, be careful when welding is performed around
them.

Do not expose parts to battery electrolyte or other acids.

Do not bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installation/removal.
