FRONT PROPELLER SHAFT
PFP:37200
On-Vehicle Service
EDS00398
APPEARANCE AND NOISE INSPECTION
●
Check the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assem-
bly.
●
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 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 the vehicle.
Propeller shaft runout limit
: 0.6 mm (0.024 in) or less

INSPECTION
●
Inspect the propeller shaft runout. If runout 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, repair or replace the journal parts.
●
Check the propeller shaft tube surface 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
PR-3, "NVH Troubleshooting Chart"
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.

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
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
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).
