5. REMOVE REAR DIFFERENTIAL FRONT OIL SEAL AND OIL SLINGER
a. Using SST, remove the oil seal.
SST 09308-10010
b. Remove the oil slinger.





6. REMOVE FRONT BEARING AND BEARING SPACER
a. Using SST, remove the front bearing from the drive pinion.
SST 0955-22010
b. Remove the bearing spacer.
7. INSTALL BEARING SPACER, FRONT BEARING AND OIL SLINGER
Install a new bearing spacer, front bearing and oil slinger.

HINT: Install the bearing spacer with its larger diameter side facing the rearward.





8. INSTALL REAR DIFFERENTIAL FRONT OIL SEAL
a. Using SST and hammer, install a new oil seal.
SST 0955-22010
Oil seal drive in depth: 2.00 ± 0.45 mm (0.0787 ± 0.0177 inch)
b. Coat MP grease to the oil seal lip.
9. INSTALL COMPANION FLANGE





a. Using SST, install the companion flange.
SST 09950-30011 (09951-03010, 09953-03010, 09950-03010, 09955-3030, 09956-03030)
b. Coat the threads of a new nut with hypoid gear oil LSD.





c. Using SST to hold the flange, torque the nut while checking the preload.
SST 09330-00021





10. ADJUST DRIVE PINION PRELOAD
Using a torque wrench, measure the drive pinion preload using the backlash between the drive pinion and ring gear.
Preload (at starting):
New bearing: 0.98 - 1.57 Nm (10 - 16 kgf-cm, 8.7 - 13.9 inch lbs.)
Reused bearing: 0.49 - 0.78 Nm (5 - 8 kgf-cm, 4.3 - 6.9 inch lbs.)
If the preload is greater than the specified value, replace the bearing spacer.
If the preload is less than the specified value, retighten the nut with a force of 13 Nm (130 kgf-cm, 9 ft. lbs.) at a time until the specified preload is reached.
Torque: 338 Nm (3,445 kgf-cm, 249 ft. lbs.) or less
If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload procedure.
Do not loosen the pinion nut to reduce the preload.
11. STAKE DRIVE PINION NUT
Using a chisel and hammer, stake the nut.
12. INSTALL PROPELLER SHAFT





13. FILL AND CHECK DIFFERENTIAL OIL LEVEL
Torque: 49 Nm (500 kgf-cm, 39 ft. lbs.)
Oil grade: Hypoid gear oil API GL-5
Viscosity:
Above -18 °C (0 °F) SAE 90
Below -18 °C (0 °F) SAE 80W-90 or 80W
Capacity: 1.15 liters (1.22 US qts, 1.01 Imp qts)
14. INSTALL NO. 1 REAR FLOOR BOARD
