7. Disconnect fuel filler hose and vent hose at the position shown
in the figure.
8. Disconnect EVAP hose at EVAP canister side.
9. Support the lower part of fuel tank with transmission jack.
CAUTION:

Support right and left part of flat bottom plate with pass-
ing board.

Because the height of right and left bottom plate is differ-
ent, horizontally support them with wood plate and things
like that.

Support the position that fuel tank mounting bands do
not engage.
10. Remove fuel tank mounting bands.
11. Supporting with hands, descend transmission jack carefully, and remove fuel tank.
CAUTION:

Make sure that all connection points have been disconnected.

Confirm there is no interference with vehicle.
12. Remove fuel filler tube, if necessary.
INSTALLATION
Note to the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten fuel hose clamp so that the distance between its lugs becomes to the following.

Before fixing fuel tank, temporarily install fuel filler tube.
CAUTION:
Use genuine fuel filler tube mounting bolts or equivalent. Make sure to tighten them to the speci-
fied torque.

To connect quick connector, refer to FL-7, "Quick Connector" .
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and rev it up and make sure there are no fuel leaks at the fuel system tube and hose connec-
tions.

On-Vehicle Inspection BES0003K
Make sure that the mounting conditions (looseness, back lash) of each component and component status
(wear, damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by placing an iron pry bar or a similar item between suspension arm and strut
assembly and prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES0003L
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen” conditions mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check Tires for improper air pressure and wear.
2. Check Road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Check Strut operation.
6. Check Each mounting point of axle and suspension for looseness and deformation.
7. Check Each link, rod, and member for cracks, deformation and other damage.
8. Check Vehicle height (posture).
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST:KV991040S0] with the following procedure on wheel, then measure wheel
alignment.
1. Remove three wheel nuts, and install the guide bolts to hub
bolts.
2. Screw adapter into the plate until it contacts the plate tightly.
3. Screw center plate into the plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide bolt nuts, do not
completely compress the spring.Axial end play : 0 mm (0 in)

FRONT SUSPENSION ASSEMBLY

5. Place the dent of alignment gauge onto the projection of center
plate and tightly contact them to measure.
CAUTION:
If camber, caster, or kingpin inclination angle is outside the
standard, check front suspension parts for wear and dam-
age. and Replace suspect parts if necessary.
Toe-In Inspection
Measure toe-in using the following procedure.
WARNING:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of vehicle before push-
ing it.
1. Bounce front of vehicle up and down to stabilize the vehicle
height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
NOTE:
If the wheels have rotated more than 180° degrees (1/2 turn),
start this procedure again from the beginning. Do not push the
vehicle backward.
6. Measure distance “B” (front side).Camber, caster, kingpin inclination angles:
