19. Pack drive ¯ange groove with grease, apply grease to O-ring
and mating surface of drive ¯ange, and install ¯ange.
20. Place snap ring in drive shaft groove. Choose snap ring so that
the gap between groove and snap ring is 0.4 mm (0.016 in) or
less.
Refer to SDS for selection of snap ring.
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary 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 improper in¯ation.
2. Check wheel runout on outside and inside.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS (FA-27).
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that shock absorbers work properly.
7. Check vehicle posture (Unladen).
CAMBER, CASTER AND KINGPIN INCLINATION
Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, Caster and Kingpin inclination:
Refer to SDS (FA-27).
2. If camber, caster or kingpin inclination is not within
speci®cation, inspect front suspension parts. Replace damaged
or worn out parts.

TOE-IN
Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a ¯at surface.
+Make sure that no person 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).
If 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-27).
7. Adjust toe-in by varying the length of steering tie-rod.
(1) Loosen lock nuts.
(2) Adjust toe-in by screwing tie-rod in and out.
Make sure both tie-rods are the same length.
(3) Tighten lock nuts to speci®ed torque.
Lock nut tightening torque:
Refer to ST section (``POWER STEERING GEAR
AND LINKAGE'').
FRONT WHEEL TURNING ANGLE
Turning angle is set by stroke length of steering gear rack and
cannot be adjusted.
1. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than 15
seconds.
Wheel turning angle (Full turn):
Refer to SDS (FA-27).
3. Adjust by stopper bolt if necessary.

7. Install bearing cap with inner bearing and adjusting shim.
Before installing seal guard, scraper, grease seal and support-
ing ring (as a unit), apply approx. 50 g (1.76 oz) of wheel bear-
ing grease to perimeters shown in ®gure at left.
Slits located in scraper and supporting ring should point
straight downward when installed.
8. When installing grease seal guard, adjust so painted surface is
visible.
Install knuckle ¯ange stopper bolt and nut on stopper side of
axle case.
After installing tie rod, adjust it to speci®ed steering angle
using turning radius gauge, then tighten with lock nut.
Knuckle Flange Grease Seal
To replace only knuckle ¯ange grease seal, proceed as follows.
REMOVAL
1. Turn steering wheel to both the extreme right and left, and
remove grease seal guard and scraper from knuckle ¯ange.
2. Extract grease seal and remove it by cutting it from axle case.
