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.

CAUTION:
Be careful not to damage the steering gear box piping dur-
ing removal.
9. Put matching marks onto propeller shaft flange yoke and final drive companion flange.
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, "

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)
