Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.
lGrasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Push and raise retaining pin to loosen it.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ``0'' when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

Precautions
lWhen installing rubber parts, final tightening must be
carried out under unladen condition* with tires on
ground.
* Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

7. Turn wheel hub several times in both directions.
8. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N´m (0.05 - 0.15 kg-m, 4.3 - 13.0 in-lb)
9. Measure wheel bearing axial end play.
Axial end play: 0 mm (0 in)
10. Measure starting force ``A'' at wheel hub bolt.
11. Install lock washer by tightening the lock nut within 15 to 30
degrees.
12. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
13. Measure starting force ``B'' at wheel hub bolt. Refer to step
10.
14. Wheel bearing preload ``C'' can be calculated as shown
below.
C=BþA
Wheel bearing preload ``C'':
7.06 - 20.99 N (0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. Repeat steps 3 through 14 until correct axial end play and
wheel bearing preload are obtained.
16. Install free-running hub.
Front Wheel Alignment
Before checking front wheel alignment, make a preliminary
inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and proper inflation.
2. Check outside and inside wheel runout.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly by using the
standard bounce test.

TOE-IN
Measure toe-in using the following procedure.
WARNING:
lAlways perform the following procedure on a flat sur-
face.
lMake sure that no one is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the 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. This mark is a measuring
point.
4. Measure distance ``A'' (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
lIf the wheels have rotated more than 180 degrees (1/2
turn), try the above procedure again from the beginning.
Never push vehicle backward.
6. Measure distance ``B'' (front side).
Total toe-in:
Refer to SDS, FA-36.
7. Adjust toe-in by varying the length of both steering tie-rods.
a. Loosen clamp bolts or lock nuts.
b. Adjust toe-in by turning both the left and right tie-rod tubes
equal amounts.
Make sure that the tie-rod bars are screwed into the tie-rod
tube more than 35 mm (1.38 in).
Make sure that the tie-rods are the same length.
Standard length (A = B):
2WD
343.9 mm (13.54 in)
4WD
297.6 mm (11.72 in)
c. Tighten clamp bolts or lock nuts, then torque them.

6. Install snap ring to anchor arm and dust cover.
Ð 2WD Ð
Make sure that the snap ring is properly installed on the
anchor arm groove.
Ð 4WD Ð
Make sure that the snap ring and anchor arm are properly
installed.
7. Tighten the adjusting nut so the torsion bar length corre-
sponds with dimension ``L'' previously measured during tor-
sion bar removal. Tighten the lock nut to specifications.
If a new torsion bar spring or anchor arm is installed, tighten
the adjusting nut to the dimension indicated in the figure at
the left, then tighten the lock nut to specifications.
Standard length ``L'':
2WD
46 mm (1.81 in)
4WD
70 mm (2.76 in)
8. Bounce vehicle with tires on ground (Unladen) to eliminate
friction of suspension.
9. Measure vehicle posture ``H''.
a. Exercise the front suspension by bouncing the front of the
vehicle 4 or 5 times to ensure that the vehicle is in a neutral
height attitude.
b. Measure vehicle posture ... Dimension ``H''.
H=AþBmm(in) ``Unladen''

3. Put matching marks on adjusting bolts and remove adjusting
bolts.
INSTALLATION
1. While aligning the adjusting bolts with the matching marks,
install the upper link.
If a new upper link or any other suspension part is installed,
align the matching mark with the slit as indicated in the fig-
ure at the left, then install the upper link.

3. Tighten adjusting bolts under unladen condition with tires on
ground.
4. After installing, check wheel alignment. Adjust if necessary.
Refer to FA-7.
DISASSEMBLY
lPress out upper link bushings.
INSPECTION
lCheck adjusting bolts and rubber bushings for damage.
Replace if necessary.
lCheck upper link for deformation and cracks. Replace if nec-
essary.
ASSEMBLY
