*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F).
*4: Canada NISSAN Au tomatic Transmission Fluid or DEXRON
TM VI type ATF may also be used.
*5: Available in mainland U.S.A. through your INFINITI dealer.
Engine Oil RecommendationINFOID:0000000001328898
NISSAN recommends the use of an energy conser ving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils
have the API certification mark on the front of the c ontainer. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

CHASSIS AND BODY MAINTENANCE
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refillsame volume with drained ATF.
 To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling, at the same time drain the old ATF
from the radiator cooler hose return side.
 When the color of the ATF coming out is almost same as the color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.
CAUTION:
 Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.
 Using ATF other than Genuine NISSAN Matic J AT F will cause deterioration in driveability and A/
T durability, and may damage the A/T, which is not covered by the warranty.
 When filling ATF, take care not to scatter heat generating parts such as exhaust.
 Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to MA-26, "
Checking A/T Fluid". If ATF is still dirty, repeat step
2. through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking Transfer FluidINFOID:0000000001328921
Check for fluid leakage and fluid level.
CAUTION:
Never start engine while checking fluid level.

5. Remove the exhaust front tube mounting nuts with a power tool. Refer to EX-3.
6. Remove the right bank three way catalyst with a power tool. Refer to EM-26, "
Removal and Installation"
(VQ35DE), EM-179, "Removal and Installation" (VK45DE).
7. Remove the power steering piping mounting bolts. Refer to PS-
37.
8. Remove the power steering gear box fixing bolts to secure work- ing area for removal of propeller shaft. Refer to PS-17
.
CAUTION:
Be careful not to damage the steering gear box piping dur-
ing removal.
9. Put matching marks onto propeller shaft flange yoke and final drive companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller shaft
flange and companion flange.
10. Remove the propeller shaft fixing bolts.
11. Set the transmission jack at the transfer, remove rear engine mounting bolts, and then lower transmission jack about 40 - 50
mm (0.16 - 0.21 in).
12. Remove propeller shaft from the front final drive and transfer.
INSPECTION
 Inspect propeller shaft runout at measuring point. If runout exceeds specifications, replace propeller shaft assembly. For mea-
suring point, refer to PR-4, "
On-Vehicle Inspection".

FRONT PROPELLER SHAFT
 As shown in the figure, while fixing yoke on one side, check axialplay of joint. If outside the standard, replace propeller shaft assem-
bly.
 Check propeller shaft for bend and damage. If damage is detected, replace propeller shaft assembly.
CAUTION:
Never disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.
 Align matching marks to install propeller shaft to final drive com-panion flange, and then tighten to specified torque. Refer to PR-4,
"Component".
CAUTION:
Never reuse the bolts.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive or transfer. Reinstall companion flange after rotating it by 90,
180, 270 degrees. Then perform driving test and check propeller
shaft vibration again at each point. Journal axial play : 0 mm (0 in)

flanges, and then tighten to specified torque. Refer to PR-8, "
Component".
 Install center bearing mounting bracket (Upper) with its arrow mark
facing forward.
 Adjust position of mounting bracket sliding back and forth to pre- vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 60, 120, 180,
240, 300 degrees. Then perform driving test and check propeller
shaft vibration again at each point.
