1 2 WHEELS AND TIRES
Regarding tire replacement:
Note the following points when tires are to be removed from or mounted onto the wheels.
1. Be careful not to scratch the tire bead, the rim bead, or the edge of the rim.
2. Apply a soapy solution to the tire bead and the edge of the rim.
3. Use a wire brush, sandpaper, or cloth to clean and remove all rust, dirt, etc., from the rim edge
and the rim bead. For aluminum wheels, use only a cloth for this purpose; never use a wire brush
or sandpaper.
4. Remove any pebbles, glass, nails, etc., embedded in the tire tread.
5. Be sure the air valve is installed correctly.
6. After mounting a tire onto a wheel, inflate the tire to 250—300 kPa (2.55—3.06 kg/cm2,35.55—42.66
psi). Check to be sure that the bead is seated correctly onto the rim and that there are no air leaks.
Then reduce the pressure to the specified level.
7. If a tire iron is used to change a tire on an aluminum wheei, be sure to use a piece of rubber be-
tween the iron lever and the wheel in order to avoid damage to the wheel. Work should be done
on a rubber mat, not on a hard or rough surface. 76G12X-006

1 3 FRONT WHEEL ALIGNMENT
FRONT WHEEL ALIGNMENT
86U13X-108
69G10X-031
Pre-inspection
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the front wheel bearing play and correct,
it if necessary.
3. Inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any
excessive looseness.
5. The vehicle must be on level ground and have no
luggage or passenger load.
6. The difference in height between the left and right
sides from the center of the wheel to the fender
brim must be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignment should be
checked simultaneously. If adjustment is
made to either the front or rear wheels,
recheck the alignment, particularly toe-in,
on all other wheels.
b) Check and adjust the steering angle trans-
fer shaft after adjusting the front wheel
alignment. (Refer to Section 10)
TOE-IN
Inspection
1. Raise the front of the vehicle until the wheels clear
the ground.
2. Turn the wheels by hand, mark a line in the center
of each tire tread using a scribing block.
3. Place the front wheels in the straight-ahead posi-
tion and lower the vehicle.
4. Measure the distance between the lines at the front
and rear of the wheels.
Both measurements must be taken at equal
distances from the ground.
Toe-in (distance greater at rear than front):
3 ± 3 mm (0.12 ± 0.12 in)
Adjustment
To adjust the toe-in, loosen the left and right tie-rod
lock nuts, then turn the tie-rods by the same amount.
Caution
a) The left and right tie-rods are both right
threaded, so, to increase the toe-in, turn the
right tie-rod toward the front of the vehicle,
and turn the left tie-rod by the same amount
toward the rear.
b) One turn of the tie-rod (both sides) changes
the toe-in by about 7.2 mm (0.28 in).
c) Tighten the tie-rod locknuts to the specified
torque.
Tightening torque: 69—98 N-m
