Removal and InstallationNGS000BX
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead direction.
2. Remove driver air bag module. Refer to SRS-42, "
Removal and Installation" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel using the steering wheel puller.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-45, "
INSTALLA-
TION" .
CAUTION:
Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off). Tool number A: ST27180001 (J-25726-A)

INSPECTION AFTER REMOVAL

Check if there is something wrong with jacket tube of steering column assembly and collar etc. And then if
they are damaged, replace with new one.

If vehicle has a collision light shocked, check column length “L”
as shown in the figure. Then if it is out of the specified value,
replace with new one.

Check the turning torque of steering column with preload gauge
(SST). If it is out of the specified value, repair it or replace with
new one.
INSTALLATION

Refer to PS-13, "COMPONENTS" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION

Check tilt and telescopic mechanism operating range “L1 ”, “L2 ”
as shown in the figure.

Check if steering wheel operation can turn to the end of the left
and right smoothly. Steering column length “L”: 572 mm (22.52 in)
Turning torque : 0 − 0.2 N·m (0 − 0.021 kg-m, 0 − 1 in-lb)

INSTALLATION

Refer to PS-18, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .

When steering wheel is set in the straight ahead direction, con-
firm slit of lower joint fits with the projection on rear cover cap,
furthermore marking position on steering gear assembly nearly
fits with the projection on rear cover cap.

After installation, bleed air from piping. Refer to PS-8, "Air
Bleeding Hydraulic System" .
INSPECTION AFTER INSTALLATION
Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
