CAUTION:
 Perform this operation in a horizo ntal position where there is a clear view for 5 m (16.4 ft) forward
and 3 m (9.84 ft) wide.
 Place the target in a well-lig hted location. (Poor lighting may make it hard to adjust.)
 The target may not be detected when there is a ligh t source within 1.5 m (4.92 ft) from either side and
within 1 m (3.28 ft) upward/downward from the target.
 Check the location of the sun. (S unlight should not shine directly on the front of the vehicle.)
 The target may not be detected when there is the same pattern of black and white as the target when
the pattern is within 1 m (3.28 ft) from either si de and upward/downward position from the target. (It
is desirable that the vehicle is positioned on the opposite side of a single-color wall.)
1.TARGET SETTING
1. Mark points “A”, “B”, “C” and “D”at the center of the lateral sur- face of each wheels.
NOTE:
Hang a string with a cone from the fender so as to pass through
the center of wheel, and then mark a point at the center of the
lateral surface of the wheel.
2. Draw line “LH” passing through points “A” and “B” on the left side
of vehicle.
NOTE:
Approximately 4 m (13.12 ft) or mo re from the front end of vehi-
cle.

6. Draw line “FW” passing through the points “E” and “F” on the front side of vehicle.
7. Mark point “X” at the center of point “E” and “F” on the line “FW”.
CAUTION:
Make sure that “E” to “X” is equal to “F” to “X”.
8. Position the center of the ri ght target to point of “X”.

1. Remove hood lock and adjust the surface height of hood, bumper molding and front fender according to
the fitting standard dimension, by rotating hood bumper rubber.
2. Loosen hood hinge mounting nuts on the hood.
3. Adjust the clearance of hood, bumper molding and fr ont fender according to the fitting standard dimen-
sion, for the hood.
4. Temporarily tighten hood lock.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from approximately 200 mm (7.874 in) height or by pressi ng hood lightly [approximately 29 N (3.0 kg, 6.5lb)].
6. Install as static closing force of hood is 680N (69.0 kg, 502lb) or less.
7. After adjustment, tighten hood hinge mounting nuts to the specified torque. CAUTION:
 Before installing hood hinge, apply anticorrosive agent onto th e mounting surface of the vehicle
body.

PINION GEAR HEIGHT
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear beari ngs into the differential shim
selector tool [SST: — (J-34309)].
 Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-7, to
secure the bearing in its proper position.
 Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the bearing to
the assembly.
 Installation of J-34309-9 and J-34309-16; place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into gear carrier. Then place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.
4. Assemble the pinion front bearing inner race and the J-34309-2 gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, turns a full 360 degrees. Tighten the two sec-
tions together by hand.
