Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ

Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.

Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.

The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.

Always pull the cable straight out from the front or rear of the vehicle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WA RN ING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: October 20052005 QX56
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: J-39565 and mechanic's 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 bro-
ken 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 GW-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.
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)

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: October 20052005 QX56
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 bumpers 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/HEADLINER
Noises in the sunroof/headliner 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 console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lense loose.
3. Loose screws at console attachment points.
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.

WINDSHIELD GLASS
Revision: October 20052005 QX56

The molding must be installed securely so that it is in position and leaves no gap.

Inform the customer that the vehicle should remain stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.

Install parts removed.
WAR NIN G:

Keep heat and open flames away as primers and adhesive are flammable.

The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.

Use in an open, well ventilated location. Avoid breathing the vapors. They can be harmful if
inhaled. If affected by vapor inhalation, immediately move to an area with fresh air.

Driving the vehicle before the urethane adhesive has completely cured may affect the perfor-
mance of the windshield in case of an accident.
CAUTION:

Do not use an adhesive which is past its usable term. Shelf life of this product is limited to six
months after the date of manufacture. Carefully adhere to the expiration or manufacture date
printed on the box.

Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.

Do not leave primers or adhesive cartridge unattended with their caps open or off.

The vehicle should not be driven for at least 24 hours or until the urethane adhesive has com-
pletely cured. Curing time varies depending on temperature and humidity. The curing time will
increase under lower temperature and lower humidity.
Repairing Water Leaks for Windshield
Leaks can be repaired without removing and reinstalling glass.
If water is leaking between the urethane adhesive material and body or glass, determine the extent of leakage.
This can be done by applying water to the windshield area while pushing glass outward.
To stop the leak, apply primer (if necessary) and then urethane adhesive to the leak point.
