Removal and Installation
INFOID:0000000006222439
REMOVAL
1.
Shift the transmission to the neutral position, and then release the parking brake.
2.
Put matching mark (A) on rear propeller shaft flange yoke and
rear drive companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller shaft
flange and final drive companion flange.
3.
Remove the propeller shaft assembly fixing bolts.
4.
Remove propeller shaft assembly from the rear final drive and
transfer.
5.
Perform inspection after removal. Refer to
INSTALLATION
Note the following, and install in the reverse order of removal.
• Align matching mark (A) to install propeller shaft flange yoke and
transfer companion flange.
• Align matching mark (A) to install propeller shaft flange yoke and
rear 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.
• If propeller shaft or final drive has been replaced, connect them as
follows:
- Install the propeller shaft while aligning its matching mark (A) with
the matching mark (B) on the joint as close as possible.
Disassembly and Assembly

DISASSEMBLY
1.
Put a matching mark between propeller shaft and flange yoke as
shown.
CAUTION:

2.
Remove snap ring.
3.
Lightly tap bottom of yoke using a copper hammer and remove
journal bearing.
CAUTION:
Never damage the yoke.
ASSEMBLY
1.
Install journal bearing to journal.
CAUTION:
• Never reuse journal or journal bearing.
• Always replace journal, journal bearing, and snap rings as a set.
• Apply multi-purpose grease to journal bearing.
2.
Install bearing (1) using a vise.
CAUTION:
Never damage bearing or flange yoke.
3.
Measure journal axial play. If necessary, select the appropriate snap ring.
a.
While pushing to 98 N·m (10 kg-m, 72 ft-lb), check the clearance
between snap ring (1) and needle bearing (2).
b.
If journal axial play is outside the specification, use a thicker/
thinner snap ring to adjust.
CAUTION:
• Never reuse snap ring.
• Select snap rings so that thickness difference between LH
and RH is within 0.02 mm (0.0008 in).

4.
Install snap ring (1).
5.
Check that joint moves smoothly.
NOTE:
The bending resistance [2.26 N.m (0.23 kg-m, 20 in-lb) or less]
may not be satisfied soon after the installation.
6.
Check the journal axial play. Refer to
.
Inspection
INFOID:0000000006222441
INSPECTION AFTER REMOVAL
Appearance
Check the propeller shaft for dents or cracks. If damage is detected, replace the propeller shaft assembly.
Propeller Shaft Runout
Check propeller shaft runout at measuring point with a dial indicator.
If runout exceeds specifications, replace propeller shaft assembly.
For measuring point, refer to
Journal Axial Play
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If axial play exceeds specifications, replace propeller
shaft assembly.
