APPEARANCE AND NOISE INSPECTION
lCheck the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assem-
bly.
lCheck the bearings for noise and damage. Repair or replace the bearings as necessary.
PROPELLER SHAFT VIBRATION
If a vibration is present at high speed, inspect the propeller shaft runout first.
1. Measure the runout of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
For measuring point, refer toPR-7, "
Propeller Shaft Runout
Measuring Point".
2. If the runout exceeds specifications, disconnect the propeller
shaft at the final drive companion flange; then rotate the com-
panion flange 90°,180°and 270°and reconnect the propeller
shaft.
3. Check the runout again. If the runout still exceeds specifications, replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle.

REMOVAL
1. Move the A/T select lever to the N position or set M/T shift lever to neutral position.
2. Release the parking brake.
3. Put matching marks on the rear propeller shaft flange yoke and
the rear final drive companion flange as shown.
CAUTION:
For matching marks, use paint. Never damage the rear pro-
peller shaft flange yoke or the companion flange.
4. Remove the bolts and nuts, then remove the propeller shaft from
the rear final drive and A/T, M/T or transfer.
INSPECTION
lInspect the propeller shaft runout. If runout exceeds the limit, replace the propeller shaft assembly.
For measuring point, refer toPR-7, "
Propeller Shaft Runout Measuring Point".
lWhile holding the flange yoke on one side, check axial play of
the joint as shown. If the journal axial play exceeds the specifi-
cation, repair or replace the journal parts.
lCheck the propeller shaft tube for dents or cracks. If damage is
detected, replace the propeller shaft assembly.

INSTALLATION
Installation is in the reverse order of removal.
lAfter installation, check for vibration by driving the vehicle. Refer toPR-2, "NVH Troubleshooting Chart".
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.
Disassembly and AssemblyEDS002WT
DISASSEMBLY
1. Put matching marks on the rear propeller shaft and flange yoke
as shown.
CAUTION:
For matching marks use paint. Never damage the rear pro-
peller shaft or flange yoke.
2. Remove the snap rings.

3. Push out and remove the journal bearings by lightly tapping the
flange yoke with a hammer, taking care not to damage the jour-
nal or flange yoke hole.
NOTE:
Put marks on the disassembled parts so that they can be rein-
stalled in their original positions from which they were removed.

4. Push out and remove the remaining journal bearings at the
opposite side by lightly tapping the flange yoke with a hammer,
taking care not to damage the journal or flange yoke hole.
NOTE:
Put marks on the disassembled parts so that they can be rein-
stalled in their original positions from which they were removed.
ASSEMBLY
1. Assemble the journal bearings. Apply multipurpose grease on
the bearing inner surface.
NOTE:
During assembly, use caution so that the needle bearings do not
fall down.
2. Select snap rings that will provide the specified play in an axial
direction of the journal, and install them. Refer toPR-12, "
Snap
Ring".
NOTE:
Select snap rings with a difference in thickness at both sides
within 0.02 mm (0.0008 in).
3. Adjust the thrust clearance between the bearing and snap ring
to zero by tapping the yoke.
4. Make sure that the journal moves smoothly and is below the
joint flex effort specification.
