APPEARANCE AND NOISE INSPECTION

Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

If center bearing is noisy or damaged, replace center bearing.
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at runout measuring points by rotating final drive companion flange with hands. For measuring
point, refer to PR-7, "
Propeller Shaft Runout Measuring Point" .
2. If runout still exceeds specifications, separate propeller shaft at final drive companion flange; then rotate companion flange 60,
120, 180, 240, 300 degrees and install propeller shaft.
3. Check runout again. If runout still exceeds specifications, replace propeller shaft assembly.
4. Check the vibration by driving vehicle.

Removal and InstallationNDS000AY
REMOVAL
1. Move the A/T select lever to N position and release the parking brake.
2. Remove the tunnel stay with power tool. Refer to RSU-5, "
REAR
SUSPENSION ASSEMBLY" .
3. Remove the center muffler with power tool. Refer to EX-3,
"EXHAUST SYSTEM" .
4. Loosen mounting nuts of center bearing mounting brackets with power tool.
CAUTION:
Tighten mounting nuts temporarily.
5. For 2WD models

Put matching marks on propeller shaft rebro joint with final
drive companion flange.
CAUTION:
For matching mark, use paint. Do not damage propeller
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.

INSPECTION

Inspect propeller shaft runout at measuring points. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-7, "
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 relevant propeller
shaft.

Check propeller shaft for bend and damage. If damage is
detected, replace relevant propeller shaft.
CAUTION:
Do not disassemble joints.

Check center bearing for noise and damage. If noise or damage
is detected, replace center bearing. Refer to PR-12, "
Disassem-
bly and Assembly of Center Bearing" .

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.
