APPEARANCE AND NOISE INSPECTION
Check the propeller shaft tube surface for dents or crac ks. If damaged, replace the propeller shaft assembly.
Check 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.
2. If the runout exceeds specif ications, 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 r unout still exceeds specifications,
replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle. Limit

While holding the flange yoke on one side, check axial play of the joint as shown. If the journal axial play
exceeds the specification, repair or replace the journal parts.
Check 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.
After installation, check for vibration by driving the vehicle. Refer to DLN-194, "NVH Troubleshooting Chart"
.
If propeller shaft assembly of final drive assembly has been replaced, connect them as follows:
- Face companion flange mark (A) of the final drive (1) upward. With
the mark (A) faced upward, couple the propeller shaft and the final
drive so that the matching mark (B) of the propeller shaft (2) can be
positioned as close as possible with the matching mark (C) of the
final drive companion flange.
- Tighten propeller shaft and final drive bolts and nuts of the to spec-
ification. Refer to DLN-196, "Removal and Installation"
.
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.

Journal
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.

Journal
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 new snap rings that will provide the specified play in an axial direction of the journal, and install them. Refer to DLN-201,
"Snap Ring".
CAUTION:
Do not reuse snap rings
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 bel ow the joint flex effort specification. Refer to DLN-
201, "General Specification".
