Front Axle and Front Suspension Parts
ICheck front axle and front suspension parts for looseness,
cracks, wear or other damage.
(1) Shake each front wheel.
(2) Make sure that cotter pin is inserted.
(3) Retighten all nuts and bolts to the specified torque.
: Refer to ªFRONT SUSPENSIONº, FA-29.
(4) Check front axle and front suspension parts for wear, cracks or
other damage.
ICheck shock absorber for oil leakage or other damage.
ICheck suspension ball joints for grease leakage and dust cov-
ers for cracks or other damage.
ICheck ball joint for vertical end play.
Upper ball joint:
1.6 mm (0.063 in) or less
(1) Jack up front of vehicle and set the stands.
(2) Clamp dial indicator onto transverse link and place indicator tip
on lower edge of brake caliper.
(3) Make sure front wheels are straight and brake pedal is
depressed.
(4) Place a pry bar between transverse link and inner rim of road
wheel.
(5) While pushing and releasing pry bar, observe maximum dial
indicator value.
(6) If ball joint movement is beyond specifications, remove and
recheck it.

Lower ball joint:
0.5 mm (0.020 in) or less
(1) Jack up front of vehicle and set the stands.
(2) Remove road wheel.
(3) Clamp dial indicator onto upper link and place indicator tip on
knuckle near ball joint.
(4) Jack up lower link [Approx. 20 mm (0.79 in)].
(5) Place a pry bar between upper link and upper link spindle.
(6) While pushing and releasing pry bar observe maximum dial
indicator value.
(7) If ball joint movement is beyond specifications, remove and
recheck it.
Front Wheel Bearing
ICheck that wheel bearings operate smoothly.
ICheck axial end play.
Axial end play: 0 mm (0 in)
IAdjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.
PRELOAD ADJUSTMENT
Adjust wheel bearing preload after wheel bearing has been
replaced or front axle has been reassembled.
Adjust wheel bearing preload as follows:
1. Before adjustment, thoroughly clean all parts to prevent dirt
entry.
2. Apply multi-purpose grease sparingly to the following parts:
IThreaded portion of spindle
IContact surface between wheel bearing washer and outer

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.
