FRONT FINAL DRIVE ASSEMBLY
Revision: 2007 April2007 M35/M45
9. Install drive gear on the mounting bolts, and then tighten to the
specified torque. Refer to FFD-15, "
COMPONENTS" .
CAUTION:
Tighten bolts in a crisscross fashion.
10. Press side bearing inner races to differential case, using the drift
and the base.
CAUTION:
Do not reuse side bearing inner race.
11. Press-fit side bearing outer race into side retainer with the drift
and the drift bar.
CAUTION:

At first, using a hammer, tap bearing outer race until it
becomes flat to side retainer.

Do not reuse side bearing outer race.
12. Press-fit side bearing outer race into gear carrier with the drift
and the drift bar.
CAUTION:

At first, using a hammer, tap bearing outer race until it
becomes flat to gear carrier.

Do not reuse side bearing outer race.
13. Place the differential case assembly into gear carrier.
14. Measure side bearing preload. If necessary, select the appropri-
ate side bearing adjusting shim. Refer to FFD-25, "
Side Bearing
Preload" .

(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
CHASSIS AND BODY MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary.
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. 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 transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.MAINTENANCE OPERATIONMAINTENANCE INTERVAL
