Revision: 2006 July 2007 FX35/FX45

As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.

Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
CAUTION:
Do not disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.

Align matching marks to install propeller shaft to final drive com-
panion flange, and then tighten to specified torque. Refer to PR-
4, "Components" .
CAUTION:
Do not reuse the bolts.

After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point. Journal axial play : 0 mm (0 in)

INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.

Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion
flanges, and then tighten to specified torque. Refer to PR-8, "
Components" .

Install center bearing mounting bracket (Upper) with its arrow
mark facing forward.

Adjust position of mounting bracket sliding back and forth to pre-
vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.

After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive. Reinstall companion flange after rotating it by 60,
120, 180, 240, 300 degrees. Then perform driving test and
check propeller shaft vibration again at each point.

If propeller shaft or final drive has been replaced, connect them
as follows:
1. Install the propeller shaft while aligning its matching mark A with the matching mark B on the joint as close as possible.
2. Tighten the joint bolts to the specified torque. Refer to PR-8,
"Components" .
CAUTION:
Do not reuse the bolts, nuts and washers.

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.
