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 ªBº at wheel hub bolt. Refer to proce-
dure 10.
14. Wheel bearing preload ªCº can be calculated as shown below.

Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary inspection.
PRELIMINARY INSPECTION
1. Check the tires for wear and proper inflation.
2. Check the wheel runout.
Wheel runout:
Refer to SDS, FA-39.
3. Check the front wheel bearings for looseness.
4. Check the front suspension for looseness.
5. Check the steering linkage for looseness.
6. Check that the front shock absorbers work properly by using
the standard bounce test.
7. Measure vehicle height (Unladen): H = A þ B mm (in)
Refer to SDS, FA-39.
(1) Exercise the front suspension by bouncing the front of the
vehicle 4 or 5 times to ensure that vehicle is in a neutral height
attitude.
(2) Measure wheel alignment.
Refer to SDS, FA-39.
(3) Measure vehicle posture ... Dimension ªHº.
Refer to SDS, FA-39.
If ªHº dimension is not within the specified value, readjust
vehicle posture using anchor arm adjusting nut.
Refer to ªINSTALLATION AND ADJUSTMENTº, ªTorsion Bar
Springº, FA-31. Adjust wheel alignment if necessary.
(4) If wheel alignment is not as specified, but dimension ªHº is
correct, adjust wheel alignment.
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 vehicle is in correct posture (unladen
vehicle).
IMeasure 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 (Unladen):
Refer to SDS, FA-39.
Kingpin inclination (Unladen):
Refer to SDS, FA-39.
Caster (Unladen):
Refer to SDS, FA-39.
ADJUSTMENT
Both camber and caster angles are adjusted by increasing or
decreasing the number of adjusting shims inserted between upper
link spindle and frame.
Before removing or installing adjusting shim(s), be sure to
place a jack under lower link.
Adjusting shim standard thickness:
4.0 mm (0.157 in)
IDo not use three or more shims at one place.
IWhen installing shim B, always face the pawl towards
spindle and insert them from bracket side. Use only one
shim in a place.
ITotal thickness of shims must be within 8.0 mm (0.315 in).
IDifference of total thickness of the front and rear must be
within 3.0 mm (0.118 in). The caster angle between the
opposite sides of the vehicle may not exceed 0É45¢.
IDetermine thickness and number of shims necessary for
adjusting camber and caster, in accordance with the fol-
lowing graph.

(2) Obtain intersection point of lines in accordance with the graph.
Front: 1.4 mm
Rear: 2.0 mm
(3) Choose shims which are nearest to the values found in the
graph:
Front: 1.6 mm
Rear: 2.0 mm
(4) If shim thicknesses as calculated appear not to be available,
combinations of different shims should be used to meet the
desired total thickness of the shims.

TOE-IN
1. Mark a base line across the tread.
After lowering front of vehicle, move it up and down to elimi-
nate friction, and set steering wheel in straight ahead position.
2. Measure toe-in.
Measure distance ªAº and ªBº at the same height as hub cen-
ter.
Toe-in (Unladen):
Refer to SDS, FA-39.
Toe-in = A þ B
3. Adjust toe-in by varying the length of steering tie-rods.
(1) Loosen clamp bolts or lock nuts.
(2) Adjust toe-in by turning the left and right tie-rod tubes an equal
amount.
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):
287 mm (11.30 in)
(3) Tighten clamp bolts or lock nuts, to the specified torque.

forward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Wheel turning angle:
Refer to SDS, FA-39.

IAfter installing auto-lock free-running hub, check operation.
When installing it, apply recommended grease to drive shaft
end.
Inspection
Thoroughly clean parts and dry with compressed air.
Brake ªAº and ªBº
Measure the thickness ªLº of brake ªAº and ªBº.
If thickness is less than the specified limit, replace brake ªAº and
ªBº as a set.
