APPEARANCE AND NOISE INSPECTION
Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at runout measuring point by
rotating final drive companion flange with hands. For measuring
point, refer to PR-4, "
Propeller Shaft Runout Measuring Point" .
2. If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 90,
180, 270 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
1. Remove engine undercover with a power tool.
2. If necessary, remove heat bracket.
3. Remove the three way catalyst (right bank) with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Put matching marks onto propeller shaft flange yoke and final
drive companion flange.
CAUTION:
For matching marks, use paint. Do not damage propeller
shaft flange and companion flange.
5. Remove the propeller shaft fixing bolts.
6. 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.

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-7, "
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-7,
"Components" .
CAUTION:
Do not reuse the bolts, nuts and washers.
