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/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 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.

TIMING CHAIN
2006 QX56
9. Remove the oil pump. Refer to LU-13, "REMOVAL" .
10. Remove the chain tensioner on the LH bank using the following steps.
NOTE:
To remove the timing chain and associated parts, start with those on the LH bank. The procedure for
removing parts on the RH bank is omitted because it is the same as that for the LH bank.
a. Squeeze the return-proof clip ends using suitable tool and push the plunger into the tensioner body.
b. Secure the plunger using stopper pin.
Stopper pin is made from hard wire approximately 1 mm (0.04
in) in diameter.
c. Remove the bolts and chain tensioner. WARNING:
Plunger, spring, and spring seat pop out when (squeezing)
return-proof clip without holding plunger head. It may
cause serious injuries. Always hold plunger head when
removing.
NOTE:
Stop the plunger in the fully extended position by using the
return-proof clip 1 if the stopper pin is removed.
Push the plunger 2 into the tensioner body while squeezing
the return-proof clip 1. Secure it using stopper pin 3.
11. Remove the timing chain tension guide and timing chain slack guide.
12. Remove the timing chain and crankshaft sprocket.
13. Loosen the camshaft sprocket bolts as shown and remove the camshaft sprocket.
CAUTION:
To avoid interference between valves and pistons, do not
turn crankshaft or camshaft when timing chain is discon-
nected.
14. Repeat the same procedure to remove the RH timing chain and associated parts.
INSPECTION AFTER REMOVAL
Check for cracks and any excessive wear at link plates. Replace
chain if necessary.
In the same way as for the LH bank, inspect the timing chain
and associated parts on the RH bank.

FUEL SYSTEMPFP:17503
Checking Fuel LinesEBS00M3Q
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsEBS00M3R
WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: INFLAMMABLE” sign in the workshop.
Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Before removing fuel line parts, carry out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-80, "FUEL PRESSURE RELEASE" .
–Disconnect the battery negative terminal.
Always replace O-rings and clamps with new ones.
Do not kink or twist hoses when they are being installed.
Do not tighten hose clamps excessively to avoid damaging
hoses.
Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Check that the screw does not contact adjacent parts.
