FRONT PROPELLER SHAFTPFP:37200
On-Vehicle ServiceEDS001W5
PROPELLER SHAFT VIBRATION
NOTE:
If a vibration is present at high speed, inspect the propeller shaft run out first.
1. Measure the run out of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
2. If the run out still exceeds specifications, disconnect the propel-
ler shaft at the final drive companion flange; then rotate the com-
panion flange 90°, 180°, 270° degrees and reconnect the
propeller shaft.
3. Check the run out again. If the run out still exceeds specifica-
tions, replace the propeller shaft assembly.
4. After installation, check for vibration by driving the vehicle.
INSPECTION
Inspect the propeller shaft tube for dents or cracks. If damaged, replace the propeller shaft assembly.

REMOVAL
1. Put matching marks on the front propeller shaft flange yoke and
the companion flange of the front final drive as shown.
CAUTION:
For matching marks, use paint. Never damage the flange
yoke and companion flange of the front final drive.
2. Remove the bolts and then remove the front propeller shaft from
the front final drive and transfer.
INSPECTION AFTER REMOVAL
Inspect the propeller shaft run out. If run out exceeds the limit,
replace the propeller shaft assembly.
While holding the flange yoke on one side, check axial play of
the joint as shown. If the journal axial play exceeds the specifi-
cation, replace the propeller shaft assembly.
Check the propeller shaft for bend and damage. 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 PR-3, "NVH Troubleshooting Chart" .
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.
Disassembly and AssemblyEDS001W7

2. Remove the snap ring.
3. Push out and remove the journal bearing by lightly tapping the
yoke with a hammer, taking care not to damage the journal or
yoke hole.
4. Remove the bearing at the opposite side in above operation.
NOTE:
Put marks on the disassembled parts so that they can be rein-
stalled in their original positions from which they were removed.
ASSEMBLY
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 snap rings that will provide the specified play in an axial
direction of the journal, and install them. Refer to PR-13, "
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.
