CAUTION:
For matching mark, use paint. Do not damage propeller
shaft flange and companion flange.
10. Remove the propeller shaft fixing bolts.
11. Set the transmission jack at the transfer, remove rear engine mounting bolts, and then lower transmission jack about 40 - 50
mm (0.16 - 0.21 in).
12. Remove propeller shaft from the front final drive and transfer.
INSPECTION

Inspect propeller shaft runout at measuring point. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-4, "
Propeller Shaft Runout Measur-
ing Point" .

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)

shaft and companion flange.
For AWD models

Put matching marks on propeller shaft flange yoke with trans-
fer companion flange and on rebro joint with final drive com-
panion flange.
CAUTION:
For matching mark, use paint. Do not damage propeller shaft flange yoke, rebro joint and com-
panion flanges.
6. Remove propeller shaft fixing bolts and nuts.
7. Remove center bearing mounting bracket fixing nuts.
8. Remove propeller shaft.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.

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.
