Inspection
NMST0020
I
When 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.
I
When the vehicle comes into a light collision, check length “L”.
Steering column length “L”:
610 mm (24.02 in)
If out of the specifications, replace steering column as an assem-
bly.

CAUTION:
I
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.
I
Remove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
I
Detach tie-rod outer sockets from knuckle arms with Tool.
1.
Remove lower joint fixing bolt (Lower side).
2.
Loosen lower joint fixing bolt (Upper side).
3.
Remove front cross bar. Refer to “Components”, SU-9.
4.
Remove steering gear assembly.

SST961C
I
Install pipe connector.
I
Observe specified tightening torque when tightening high-pres-
sure pipe connectors. Excessive tightening will damage
threads of connector or O-ring.
Connector tightening torque:
1 High-pressure side
15 - 25 N·m (1.5 - 2.5 kg-m, 11 - 18 ft-lb)
SST824A
I
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).
SST819A
I
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.
I
To install, set left and right dust boots to equal deflection.
Attach lower joint by aligning matching marks of pinion shaft
and pinion housing.
SST962C
I
Tighten gear housing mounting bracket bolts in the order
shown.
Temporary tightening torque:
78 N·m (8.0 kg-m, 58 ft-lb)
Secure tightening torque:
88 - 108 N·m (9.0 - 11.0 kg-m, 65 - 80 ft-lb)
SST131C
Disassembly
NMST0023
1.
Prior to disassembling, measure pinion rotating torque. Record
the pinion rotating torque as a reference.
I
Before measuring, disconnect gear housing tube and
drain fluid.
I
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.
Gear sub-assembly cannot be disassembled. If it is faulty,
replace with a new one.
