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.

3. Tighten wheel bearing lock nut with Tool.
:78-98N×m
(8 - 10 kg-m, 58 - 72 ft-lb)
4. Turn wheel hub several times in both directions.
5. Loosen wheel bearing lock nut so that torque becomes 0 N×m
(0 kg-m, 0 ft-lb).
6. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N×m
(0.05 - 0.15 kg-m,4-13in-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,4-13in-lb)
9. Measure wheel bearing axial end play.
Axial end play:
0mm(0in)
10. Measure starting force ªAº at wheel hub bolt when moving the
hub by 90É as shown.
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.
C=BþA
Wheel bearing preload ªCº:
7.06 - 20.99 N
(0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. Repeat above procedures until correct axial end play and wheel
bearing preload are obtained.
16. Install free-running hub and brake pads.

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.

Shock Absorber
REMOVAL AND INSTALLATION
When removing and installing shock absorber, do not allow oil or
grease to come into contact with rubber parts.
INSPECTION
Wash all parts, except for nonmetallic parts, with suitable solvent
and dry with compressed air.
Blow dirt and dust off of nonmetallic parts with compressed air.
ICheck for oil leakage and cracks. Replace if necessary.
ICheck piston rod for smooth operation. Replace if necessary.
ICheck rubber parts for wear, cracks, damage or deformation.
Replace if necessary.
Torsion Bar
REMOVAL
IRemove torsion bar as follows:
(1) Remove anchor arm bolt nuts and remove anchor arm bolt and
pilot.
Remove snap ring and dust cover from rear torsion bar anchor
arm.
(2) Withdraw torsion bar and remove torsion bar and torsion bar
rear anchor arm as an assembly from front torsion bar torque
arm.
(3) Remove torsion bar from rear torsion bar anchor arm.
INSPECTION
ICheck torsion bar for wear, twist, bend and other damage.
ICheck serrations of each part for cracks, wear, twist and other
damage.
ICheck dust cover for cracks.
