FRONT OIL SEAL
8. Remove the front oil seal using Tool as shown.
INSTALLATION
1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly to the gear carrier
using Tool.
CAUTION:
 Do not reuse front oil seal.
 Do not incline the new fron t oil seal when installing.
 Apply multi-purpose grease to the lips of the new front oil seal.
2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using suitable tool A, and
check the total preload torque using Tool B.
 The total preload torque should be within the total preload
torque specification. When not replacing the collapsible
spacer, it should also be equal to the measurement taken dur-
ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).
 If the total preload torque is low, tighten the drive pinion lock nut in 6.8 N·m (0.69 Kg-m, 5ft-lb) increments until the total pre-
load torque is met.
CAUTION:
 Do not reuse drive pinion lock nut.
 Apply anti-corrosive oil to th e threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
 Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to DLN-217, "Disassembly and
Assembly".
 Do not loosen drive pinion lock nut to adjust the total preload torque. If the drive pinion lock nut
torque or the total preload torque exceeds the sp ecifications, replace the collapsible spacer and
tighten it again to adjust. Refer to DLN-217, "Disassembly and Assembly"
.
 After adjustment, rotate drive pinion back and fo rth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.

• See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and tools). Have the driver
or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and c ounterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog lamp lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.
• When performing adjustment, if necessary, cover the head-lamps and opposite fog lamp.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
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 c an 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 c onsole panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the c onsole at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the pos ition 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 thes e 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 installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation 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.

FUEL TANK
REMOVAL
WARNING:
Follow the “General Precautions” before working on the fuel system. Refer to FL-4, "
General Precau-
tion".
1. Remove the fuel filler cap to release the pressure from inside the fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-487, "
Fuel Pressure Check".
3. Drain the fuel from the fuel tank, if necessary.
a. Position the vehicle so it is level.
b. Check the fuel level on level gauge. If the fuel gauge indicates more than the level as shown (full or almost full), drain the fuel
from the fuel tank until the fuel gauge indicates the level as
shown, or less.
c. Use the following procedure to drain the fuel to the specified level after disconnecting the fuel filler hose from the fuel filler
pipe.
• Insert a suitable hose of less than 15 mm (0.59 in) diameterinto the fuel filler pipe through the fuel filler opening to drain
the fuel from fuel filler pipe.
• Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.
NOTE:
As a guide, the fuel level reaches the fuel gauge position as shown, or less, when approximately 14
liters (3 3/4 US gal, 3 1/8 Imp gal) of fuel are drained from the fuel tank.
4. Remove the LH rear wheel and tire. Refer to WT-41, "
Adjustment".
5. Remove the four clips and remove the rear fender protector, front.
6. Disconnect the fuel filler hose from the fuel filler pipe and dis- connect the vent hose quick connector.
7. Remove the second row seat and the third row LH seat. Refer to SE-55, "
Removal and Installation" (sec-
ond row), SE-58, "
LH Side Seat" (third row).
8. Disconnect the battery negative terminal. Refer to PG-76, "
Removal and Installation".
9. Remove the second and third row rear seat belt buckles mounted on the floor. Refer to SB-7, "
Removal
and Installation of Second Row Seat Belt", SB-9, "Removal and Installation of Third Row Seat Belt".
10. Remove the LH center pillar trim, the LH rear trim panel, and the LH rear side door kick plate and weather
stripping. Refer to INT-14, "
Removal and Installation".
11. Remove the second row rear center console and base. Refer to IP-21, "
Removal and Installation".
12. Reposition the floor carpet out of the way to access the inspection hole cover, located under the center LH
rear seat.
13. Fuel filler hose grommet 14. Fuel filler cap 15. Fuel tank shield
