FRONT PROPELLER SHAFT
Revision: 2004 November 2004 FX35/FX45
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.
Removal and InstallationADS000KM
REMOVAL
1. Remove the front and rear engine undercover with power tool.
2. Remove the front cross bar with power tool. Refer to FSU-6, "
FRONT SUSPENSION ASSEMBLY" .
3. Remove the exhaust front tube bracket with power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Disconnect the heated oxygen sensor harness connector.
5. Remove the exhaust front tube mounting nuts with power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
6. Remove the right bank catalytic converter with power tool. Refer to EM-26, "
Removal and Installation"
(VQ35DE) or EM-178, "Removal and Installation" (VK45DE).
7. Remove the power steering piping mounting bolts. Refer to PS-
41, "HYDRAULIC LINE" .
8. Remove the power steering gear box fixing bolts to secure work-
ing area for removal of propeller shaft. Refer to PS-19, "
POWER
STEERING GEAR AND LINKAGE" .
CAUTION:
Be careful not to damage the steering gear box piping dur-
ing removal.Propeller shaft runout limit : 0.6 mm (0.024 in) or less

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
