Differential Case Ð 2-pinion type Ð
1. Install side gears, pinion mate gears and thrust washers into
differential case.
2. Fit pinion mate shaft to differential case so that it meets lock pin
holes.
3. Adjust backlash between side gear and pinion mate gear by
selecting side gear thrust washer. Refer to SDS.
Backlash between side gear and pinion mate gear
(Clearance between side gear thrust washer and dif-
ferential case):
0.15 - 0.20 mm (0.0059 - 0.0079 in)
4. Install pinion mate shaft lock pin with a punch.
Make sure lock pin is ¯ush with case.
5. Apply gear oil to gear tooth surfaces and thrust surfaces and
make sure they turn properly.
6. Install differential case assembly on ring gear.
Tighten bolts in a criss-cross pattern, lightly tapping bolt head
with a hammer.

Installation Ð Air Bag Module and Spiral Cable
1. Set the front wheels in the straight-ahead position.
2. Make sure that the spiral cable is in the neutral position. The
neutral position is detected by turning left about 2.5 revolutions
from the right end position. Align the two marks (
,
m).
CAUTION:
+The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
+Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned to the left
about 2.5 turns from the right end position.
3. Connect and lock spiral cable connector and tighten with
screws. Install steering column cover.
4. Install steering wheel, aligning with spiral cable pin guides, and
pull spiral cable through.
5. Connect horn connector and engage spiral cable with pawls in
steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
6. Tighten nut.
:29-39Nzm (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
7. Position air bag module and tighten with new special bolts.
8. Connect air bag module connector.
9. Install all lids.
10. Conduct self-diagnosis to ensure entire SRS operates properly.
(Use CONSULT or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
11. Turn steering wheel to the left end and then to the right end fully
to make sure that spiral cable is set in the neutral position.
If air bag warning lamp blinks or stays ON (at the User mode),
it shows the spiral cable may be snapped due to its improper
position. Perform self-diagnosis again (use CONSULT or warn-
ing lamp). If a malfunction is detected, replace the spiral cable
with a new one.
12. Perform self-diagnosis again to check that no malfunction is
detected.
Installation Ð Front Passenger Air Bag Module
+Always work from the side of air bag module.
1. Install front passenger air bag module on steering member.
+Ensure harness is not caught between rear of air bag module
and steering member.
2. Connect in¯ator connector to body harness connector.
3. Install in¯ator connector on steering member.

Checking Steering Wheel Play
+With wheels in a straight-ahead position, check steering wheel
play.
Steering wheel play:
35 mm (1.38 in) or less
+If it is not within speci®cation, check the following for loose and
worn components.
Steering gear assembly
Steering linkage
Steering column
Front suspension and axle
Checking Neutral Position on Steering Wheel
Pre-checking
+Make sure that wheel alignment is correct.
Wheel alignment:
Refer to SDS in FA section.
+Verify that the steering gear is centered before removing the
steering wheel.
Checking
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and
reinstall it correctly.
3. If the neutral position is between two teeth, loosen drag link lock
nuts. Adjust neutral position by turning drag link adjuster.
Front Wheel Turning Angle
1. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Turning angle of full turns:
Refer to SDS in FA section.
2. If not within speci®cation, adjust using stopper bolt.

CAUTION:
+The rotation of the spiral cable (SRS ``Air bag'' component
part) is limited. If the steering gear must be removed, set
the front wheels in the straight-ahead direction. Do not
rotate the steering column while the steering gear is
removed.
+Remove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
STEERING WHEEL
+Remove air bag module and spiral cable. Refer to RS section
(``Removal Ð Air Bag Module and Spiral Cable'', ``SUPPLE-
MENTAL RESTRAINT SYSTEM'').

+Align spiral cable correctly when installing steering wheel.
a. Set the front wheels in the straight-ahead position.
b. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left 2.5 revolutions
from the right end position. Align the two marks (
,
m).
CAUTION:
The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable may
snap by turning the steering wheel beyond the limited number
of turns. (The spiral cable can be turned up to 2.5 turns from
the neutral position to both the right and left.)
+Remove steering wheel with Tool.
STEERING COLUMN
+When installing steering column, ®ngertighten all lower bracket
and clamp retaining bolts; then tighten them securely. Do not
apply undue stress to steering column.
+When attaching coupling joint, be sure tightening bolt faces
cutout portion.

b. Turn stub shaft all the way to right and left several times.
c. Measure turning torque at 360É position from straight-ahead
position with Tools.
Turning torque at 360É
0.15 - 0.78 Nzm (1.5 - 8.0 kg-cm, 1.3 - 6.9 in-lb)
2. Measure turning torque at straight-ahead position.
Straight-ahead position is a position where stub shaft is
turned 2.14 turns (two full turns and 50É) from lock position.
Turning torque at straight-ahead position:
0.2 - 0.5 Nzm (2 - 5 kg-cm, 1.7 - 4.3 in-lb)
higher than turning torque at 360É
Maximum turning torque:
0.44 - 1.18 Nzm (4.5 - 12 kg-cm, 3.9 - 10.4 in-lb)
3. Check sector shaft end play in neutral position.
End play:
