INSTALLATION
Note to the following, and install in the reverse order of removal.
Fuel Level Sensor Unit
1. Install new seal packing to fuel tank without any twist.
2. Align (B) with (A) as shown in the figure. Install fuel level sensor
unit, fuel filter and fuel pump assembly to fuel tank (C).
CAUTION:
 Never allow seal packing to drop.
 Never bend float arm during installing.
3. Install seal packing for fuel level sensor unit, fuel filter and fuel
pump assembly with lock ring wrench (commercial service tool)
by turning clockwise.
CAUTION:

InspectionINFOID:0000000003793253
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leakage.
1. Turn ignition switch “ON” (with engine stopped), then check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and let it idle and check there are no fuel leakage at the fuel system connections.

PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003890157
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for SuspensionINFOID:0000000003811111
CAUTION:
 When installing rubber bushings, the final tightening must be carried out under unladen conditions
with tires on ground. Oil might 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. Spare tire, jack, hand tools
and mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are
pre-oiled, tighten as they are.

INSPECTION
Description
CAUTION:
 Camber, caster, kingpin inclination angles cannot be adjusted.
 If camber, caster, or kingpin inclination angle exceeds the standard value, check front suspension
parts for wear and damage. Replace suspect parts if a malfunction is detected.
 Kingpin inclination angle is reference value, no inspection is required.
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
Preliminary Check
Check the following:
 Tires for improper air pressure and wear
 Road wheels for runout: Refer to WT-2, "
Inspection".
 Wheel bearing axial end play: Refer to FA X - 6 , "
Inspection".
 Transverse link ball joint axial end play: Refer to FSU-11, "
Inspection".
 Strut operation.
 Each mounting part of axle and suspension for looseness and deformation
 Each of suspension member and transverse link for cracks, deformation and other damage
 Vehicle height (posture)
CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES
 Camber, caster, kingpin inclination angles cannot be adjusted.
 Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand at the
same height so that vehicle remains horizontal.
Using a CCK Gauge
Install the CCK gauge attachment (SST: KV991040S0) with the following procedure on wheel, then measure
wheel alignment.
1. Remove three wheel to nuts, and install the guide bolts to hub
bolt.
2. Screw the adapter into the plate until it contacts the plate tightly.
3. Screw the center plate into the plate.
4. Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.
5. Place the dent of alignment gauge onto the projection of the
center plate and tightly contact them to measure.
CAUTION:
 If camber, caster, or kingpin inclination angle exceeds the
standard value, check front suspension parts for wear and
damage. Replace suspect parts if a malfunction is
detected.

If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Precaution for Procedure without Cowl Top CoverINFOID:0000000003852857
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsINFOID:0000000003852781
 Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
 Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
 When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
