7. Measure drive gear-to-drive pinion backlash with a dial indicator
at several point.

It backlash is too small, adjustment of washer thickness is required. Decrease thickness of left shim
and increase thickness of right by the same amount.
If backlash is too great, reverse the above procedure.

Never change the total amount of washers as it will change the bearing preload.
8. Check total preload with tool.
When checking preload, turn drive pinion in both directions several times to seat bearing rollers correctly.

If preload is too great, remove the same amount of washer to each side.

If preload is too small, add the same amount of washer to each side.
Never add or remove a different number of washers for each side. Difference in number of washers will
change drive gear to drive pinion backlash.
9. Recheck drive gear to drive pinion backlash. Increase or decrease in thickness of shims will cause
change to drive gear to pinion backlash.

Check whether the backlash varies excessively in different places. Foreign matter may be caught
between the drive gear and the differential case causing the trouble.

The backlash can vary greatly even when the drive gear runout is within a specified range. In that case,
replace the hypoid gear set or differential case.
10. Check runout of drive gear with a dial indicator.
11. Check tooth contact.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Revision: 2004 November 2004 FX35/FX45
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 room.
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.

AWD SYSTEMPFP:41650
Power Transfer DiagramADS000RV
System DescriptionADS000RW
DESCRIPTION

Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.

Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.

On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.

Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:

When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.

If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.

When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)

If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.

When the difference of revolution speed between the front and rear wheel with AUTO mode the shift occa-
sionally changes to direct 4-wheel driving conditions automatically. This is not malfunction.
