FRONT PROPELLER SHAFTPFP:37200
On-Vehicle ServiceADS000KL
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at several points by rotating final
drive companion flange with your hands.
2. If runout still exceeds specifications, disconnect propeller shaft
at the final drive companion flange; then rotate companion
flange 90, 180, 270 degrees and reconnect propeller shaft.
3. Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4. Check the vibration by driving the vehicle.
APPEARANCE CHECKING

Inspect propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

9. Put matching marks on propeller shaft flange and companion
flange on the front drive as shown.
CAUTION:
For matching mark, use paint. Never damage the propeller
shaft flange and companion flange on the front drive.
10. Set the transmission jack at the transfer, remove the mounting
bolts and rear engine mounting bracket. On the VK45DE engine,
lower the transmission jack about 40 - 50 mm (0.16 - 0.20 in).
11. Remove the bolts and then remove the propeller shaft from the
front final drive and transfer.
INSPECTION
1. As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2. Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
INSTALLATION
Note the following, install in the reverse order of removal.

Install the propeller shaft into the transfer.

Install the propeller shaft onto the front final drive flange while
matching marks that are marked during removal.

Tighten the drive flange bolts to specified torque.
CAUTION:
Do not reuse the bolts and nuts. Always replace it with a
new one.

After installation, check the vibration by driving the vehicle. If the
vibration is present, remove the propeller shaft from the final
drive companion flange and turn the propeller shaft 90, 180 or
270 degrees and reinstall the propeller shaft to the companion
flange.
Recheck the vibration by driving the vehicle.

PROPELLER SHAFT VIBRATION
CAUTION:
If vibration is present at high speed, check mounting between propeller shaft and companion flange.
If vibration is present at high speed, check propeller shaft runout first.
1. Measure propeller shaft runout at several points by rotating final
drive companion flange with your hands.
2. If runout still exceeds specifications, disconnect propeller shaft
at final drive companion flange: then rotate companion flange
90, 180, 270 degrees and reconnect propeller shaft.
3. Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4. Perform driving test to check.
5. If the runout exceeds the service limit, do the following:

Remove the propeller shaft from the final drive companion flange.

Turn the propeller shaft 60, 120, 180, 240, 300 degrees and reinstall the propeller shaft to the compan-
ion flange, then measure the runout again.

If the runout still exceeds the service limit, replace the propeller shaft assembly.

Check the vibration by driving the vehicle.
APPEARANCE AND NOISE INSPECTION

Inspect propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

If center bearing is noisy or damaged, replace propeller shaft assembly.Propeller shaft runout limit : 0.6 mm (0.024 in) or less

INSTALLATION
1. Paying attention to following items, install in the reverse order of removal.
a. Install the propeller shaft onto the rear final drive companion
flange while aligning the matching marks that are marked during
removal.
b. Adjust position of the bearing cushion so as not to apply thrust
play to the center bearing insulator.
c. Position the bearing cushion overlap as shown in the figure.
d. Install the center bearing bracket (upper) with its arrow mark fac-
ing forward.
e. Tighten the center bearing mounting bracket (upper) fixing nuts
to specified torque.
CAUTION:
Do not reuse the nuts. Always replace the nuts with a new
ones.
2. If companion flange has been removed, put new alignment
matching mark C on it. Then, reassemble using the following
procedure.
Perform these steps when either of final drive and propeller
shaft is replaced with a new one.
a. Erase original mark C from companion flange with suitable sol-
vent.
b. Measure companion flange vertical runout.
c. Determine the position where maximum runout is read on dial
gauge. Put mark (shown by C in figure) on flange perimeter cor-
responding to maximum runout position.

CAUTION:
Do not reuse the bolts, and washers. Always replace the
them with new ones.

After installation, check the vibration by driving the vehicle. If the vibration is present, remove the pro-
peller shaft from the final drive companion flange.

Turn the propeller shaft 60, 120, 180, 240 or 300 degrees and reinstall the propeller shaft to the com-
panion flange, then measure the runout again by driving the vehicle on each angle position.
