General Pre-
cautions" .

Drain fuel from fuel tank if necessary. Refer to FL-4, "REMOVAL" .
CAUTION:
For the safety work and to maintain fuel tank gravity at center, drain fuel to the level where fuel
tank weight at left and right becomes equal.

Perform work on level place.

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.

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003G

When installing rubber bushings, final tightening must be performed under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-lock nut are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

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)

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
