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.

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.

3. If the propeller shaft or final drive has been replaced, connect
the propeller shaft and final drive as follows:
NOTE:
Avoid damaging the rebro joint boot, protect it with a shop towel
or equivalent.
Install the propeller shaft while aligning its matching mark A
with the mark C on the joint as close as possible.
Tighten the joint bolts/nuts to specified torque.
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.
Disassembly and AssemblyADS000KN
DISASSEMBLY
Center Bearing
NOTE:
The joint cannot be disassembled.
The center bearing can be disassembled.
1. Remove the propeller shaft assembly from the vehicle. Refer to PR-8, "
REMOVAL" .
2. Put matching marks on propeller shaft and center flange, then
disassemble the 1st and 2nd propeller shaft.
CAUTION:
For matching mark, use paint. Never damage the propeller
shaft flange and center flange.
3. Put matching marks onto the center flange and propeller shaft
end as shown.
4. Stake center flange lock nut with a punch (except 3F80A-
1VL107- type/VK45DE, AWD).

5. Hold the center flange using a flange wrench, and remove the
lock nut.
6. Remove the center flange using a commercial available bearing
puller.
7. Press out the center bearing using a puller and hydraulic press.
ASSEMBLY
1. Apply multi-purpose grease to the each end of the center bear-
ing and each face of the washer.
2. For the 3S80A-1VL107 (VQ35DE/2WD) and 3F80A-1VL107
(VK45DE/AWD) type, install the center bearing with its “F” mark
facing the front of the vehicle.
For the 3F80A-1VL107(VQ35DE/AWD) type, install the center
bearing with its “F” mark facing the rear of the vehicle.
3. Install the washer.
4. Install the center flange onto the propeller shaft with aligning the
marks that are marked while removal.
5. Install and tighten the new lock nut to specified torque using a
torque wrench.
For the 3S80A-1VL107 (VQ35DE/2WD) and 3F80A-1VL107 (VQ35DE/AWD) type, tighten the lock nut to
specified torque.
6. For the 3S80A-1VL107 (VQ35DE/2WD) and 3F80A-1VL107
(VQ35DE/AWD) type, place a piece of wood under the center
flange, stake the lock nut against the propeller shaft groove.
CAUTION:
Do not use the lock nut. Always replace the lock nut with a
new one.
7. Temporality tighten the lock nut to the following torque.
Loosen the lock nut, then retighten it to specified torque.
For 3F80A-1VL107 (VK45DE/AWD) type, tighten the lock nut to
specified torque.
CAUTION:
Do not reuse the lock nut. Always replace the lock nut with
a new one.Tool number : KV40104000 ( – )
