On-vehicle Service
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout
®rst.
1. Raise front and rear wheels.
2. Measure propeller shaft runout at several points by rotating
®nal drive companion ¯ange with hands.
Runout limit: 0.6 mm (0.024 in)
3. If runout exceeds speci®cations, disconnect propeller shaft at
®nal drive companion ¯ange; then rotate companion ¯ange 180
degrees and reconnect propeller shaft.
4. Check runout again. If runout still exceeds speci®cations,
replace propeller shaft assembly.
5. Perform road tests.
APPEARANCE CHECKING
+Inspect propeller shaft tube surface for dents or cracks. If
damaged, replace propeller shaft assembly.

Removal and Installation
+Put matchmarks on ¯anges and separate propeller shaft from
®nal drive.
CAUTION:
When installing the propeller shaft, make sure it is facing the
correct direction. Each model is different.
Inspection
+Inspect propeller shaft runout. If runout exceeds speci®cations,
replace propeller shaft assembly.
Runout limit: 0.6 mm (0.024 in)
+Inspect journal axial play.
If the play exceeds speci®cations, replace propeller shaft
assembly.
Journal axial play:
0.02 mm (0.0008 in) or less
+Check ¯ange yoke and sleeve yoke for damage or wear.
Replace if necessary.
Disassembly
JOURNAL
1. Put matchmarks on shaft and ¯ange or yoke.

2. Remove snap ring.
3. Remove pushed out journal bearing by lightly tapping yoke with
a hammer, taking care not to damage journal and yoke hole.
4. Remove bearing at opposite side in above operation.
Put marks on disassembled parts so that they can be rein-
stalled in their original positions from which they were
removed.
Assembly
JOURNAL
1. Assemble journal bearing. Apply recommended multi-purpose
grease on bearing inner surface.
When assembling, be careful that needle bearing does not fall
down.
2. Select snap ring that will provide speci®ed play in axial direc-
tion of journal, and install them. (Refer to SDS.)
Select snap rings with a difference in thickness at both sides
within 0.06 mm (0.0024 in).

3. Adjust thrust clearance between bearing and snap ring to zero
by tapping yoke.
4. Check to see that journal moves smoothly and check for axial
play.
Axial play: 0.02 mm (0.0008 in) or less
