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
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-
●
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
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.

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-6, "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.
