NOISE
Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1.
With a dial indicator, measure propeller shaft runout at runout
measuring points by rotating final drive companion flange with
hands.
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.

6.
Put matching mark onto propeller shaft flange yoke and final
drive companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller shaft
flange and final drive companion flange.
7.
Remove the propeller shaft assembly fixing bolts.
8.
Remove propeller shaft assembly from the front final drive and
transfer.
CAUTION:
Never damage the transfer front oil seal.
9.
Hang steering hydraulic line not to interfere with work. Refer to
.
10. Remove propeller shaft assembly from O-ring.
INSTALLATION
Note the following, and install in the reverse order of removal.
• Align matching mark to install propeller shaft assembly to final
drive companion flange.
• 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 90, 180, 270
degrees. Then perform driving test and check propeller shaft vibra-
tion again at each point.
CAUTION:
• Never damage the transfer front oil seal.
• Never reuse O-ring.
• Apply multi-purpose grease onto O-ring.
