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.

Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, adjust wheel bearing end play, then
check ball joint end play.
lMake sure that the cotter pin is inserted.
lRetighten all nuts and bolts to the specified torque.
: Refer to ``FRONT SUSPENSION'', FA-26.
lCheck front axle and front suspension parts for wear, cracks
or other damage.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play: 0 mm (0 in)
lAdjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.
PRELOAD ADJUSTMENT (2WD)
Adjust wheel bearing preload after wheel bearing has been
replaced or front axle has been reassembled.
1. Before adjustment, thoroughly clean all parts to prevent dirt
entry.
2. Apply multi-purpose grease sparingly to the following parts:
lRubbing surface of spindle
lContact surface between lock washer and outer wheel bear-
ing
lHub cap (as shown at left)
lGrease seal lip
3. Tighten wheel bearing lock nut to the specified torque.
: 34 - 39 N´m (3.5 - 4.0 kg-m, 25 - 29 ft-lb)
4. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
5. Again tighten wheel bearing lock nut to the specified torque.
: 34 - 39 N´m (3.5 - 4.0 kg-m, 25 - 29 ft-lb)

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.

7. Measure vehicle height (Unladen):H=AþBmm(in)
Refer to SDS, FA-36.
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 wheel alignment.
Refer to SDS, FA-36.
c. If wheel alignment is not as specified, adjust vehicle posture.
Refer to SDS, FA-36.
d. Adjust wheel alignment.
Refer to SDS, FA-36.
CAMBER, CASTER AND KINGPIN INCLINATION
Before checking camber, caster or kingpin inclination, move
vehicle up and down on turning radius gauge to minimize
friction. Ensure that the vehicle is in correct posture.
lMeasure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge and adjust
in accordance with the following procedures.
Camber, Caster and Kingpin inclination:
Refer to SDS, FA-36.
lIn the following two cases, temporarily tighten the adjusting
bolts while aligning the matching marks with the slits as
shown in the figure at the left and measure the camber,
caster and kingpin inclination:
(1) When replacing the upper link or other suspension parts
with new ones
(2) When matching marks were not painted on adjusting
bolts before suspension disassembly procedures
lIf matching marks were already painted during suspension
disassembly, align the matching marks with the slits, then
temporarily tighten the adjusting bolts. Measure the camber,
caster and kingpin inclination.
