1. Air bag module
2. Steering wheel
3. Combination switch with spiral
cable4. Column cover
5. Steering column assembly
6. Hole cover7. Lower joint
8. Lower cover
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.

Refer to RS-29, “Removal — Driver Air Bag Module and Spiral
Cable”.

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 about 3.5 revo-
lutions from the right end position. Align the two marks (
)or
make sure that the white indicator is visible in the upper part
of the indicator window, with the cable pointed downwards.
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 about 3.5 turns
from the neutral position to both the right and left.)

When installing steering column, fingertighten 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.
SST491C
Align slit of lower joint with projection on dust cover. Insert joint
until surface A contacts surface B.
CAUTION:
After installation, turn steering wheel to make sure it moves
smoothly. Ensure the number of turns are the same from the
straight forward position to left and right locks. Be sure that
the steering wheel is in a neutral position when driving
straight ahead.

InspectionNJST0020When steering wheel does not turn smoothly, check the steer-
ing column as follows and replace damaged parts.
a) Check column bearings for damage or unevenness. Lubricate
with recommended multi-purpose grease or replace steering
column as an assembly, if necessary.
b) Check jacket tube for deformation or breakage. Replace if
necessary.
When the vehicle comes into a light collision, check length “L”.
Steering column length “L”:
Refer to SDS, ST-29.
If out of the specifications, replace steering column as an assem-
bly.

TILT MECHANISMNJST0020S01After installing steering column, check tilt mechanism opera-
tion.

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.
Detach tie-rod outer sockets from knuckle arms with Tool.
1. Remove stabilizer fixing bolts. Refer to SU-11, “Removal and
Installation”.
2. Disconnect lower joint.
3. Remove gear housing mounting bracket fixing bolts.
4. Remove steering gear assembly.

Install pipe connector.
Observe specified tightening torque when tightening high-pres-
sure and low-pressure pipe connectors. Excessive tightening
will damage threads of connector or O-ring.
Connector tightening torque:
1 Low-pressure side
27 - 39 N·m (2.8 - 4.0 kg-m, 20 - 29 ft-lb)
2 High-pressure side
15 - 25 N·m (1.5 - 2.5 kg-m, 11 - 18 ft-lb)
The O-ring in low-pressure pipe connector is larger than that
in high-pressure connector. Take care to install the proper
O-ring.
SST824A
Initially, tighten nut on tie-rod outer socket and knuckle arm to
29 to 39 N·m (3 to 4 kg-m, 22 to 29 ft-lb). Then tighten further
to align nut groove with first pin hole so that cotter pin can be
installed.
CAUTION:
Tightening torque must not exceed 49 N·m (5 kg-m, 36 ft-lb).
NOTE:
Only the dust boot, tie-rod inner socket and tie-rod outer socket can
be disassembled on models for Europe.
SST819A
Before removing lower joint from gear, set gear in neutral
(wheels in straight-ahead position). After removing lower joint,
put matching mark on pinion shaft and pinion housing to record
neutral position.
To install, set left and right dust boots to equal deflection.
Attach lower joint by aligning matching marks of pinion shaft
and pinion housing.
Tighten gear housing mounting bracket bolts.
SST862CB
DisassemblyNJST00231. Prior to disassembling, measure pinion rotating torque. Record
the pinion rotating torque as a reference.
Before measuring, disconnect gear housing tube and
drain fluid.
Use soft jaws when holding steering gear housing. Handle
gear housing carefully, as it is made of aluminum. Do not
grip cylinder in a vise.
2. Remove gear sub-assembly, O-ring and shim.
Gear sub-assembly cannot be disassembled. If it is faulty,
replace with a new one.
