Note
Apply grease to the threads and tip of the SST center bolt before use.
REMOVE REAR DIFFERENTIAL CARRIER OIL SEAL
Using SST, remove the oil seal from the differential carrier.
Note
Apply grease to the threads and tip of the SST center bolt before use.
REMOVE REAR DIFFERENTIAL DRIVE PINION OIL SLINGER
REMOVE REAR DRIVE PINION FRONT BEARING

Note
Apply grease to the threads and tip of the SST center bolt before use.
Using SST, remove the outer race of the rear drive pinion front tapered roller bearing from the differential carrier.
REMOVE DIFFERENTIAL OIL STORAGE RING
Using a screwdriver and hammer, tap out the oil storage ring.
REMOVE REAR DIFFERENTIAL DRIVE PINION BEARING SPACER
INSTALL REAR DIFFERENTIAL DRIVE PINION BEARING SPACER
Install a new drive pinion bearing spacer to the drive pinion.
Note
Be sure to face the larger inner diameter side rearward as shown in the illustration.
INSTALL DIFFERENTIAL OIL STORAGE RING
Using a brass bar and hammer, tap in a new oil storage ring.
Note
Be careful not to damage the oil storage ring.
INSTALL REAR DRIVE PINION FRONT BEARING
Using SST and hammer, tap in the outer race of the rear drive pinion front tapered roller bearing.
Install the inner race of the rear drive pinion front tapered roller bearing.
INSTALL REAR DIFFERENTIAL DRIVE PINION OIL SLINGER
INSTALL REAR DIFFERENTIAL CARRIER OIL SEAL
Using SST and a hammer, install a new oil seal.
| Oil seal drive in depth |
|---|
| 0.4 to 1.0 mm (0.0158 to 0.0393 in.) |
Apply MP grease to the oil seal lip.
INSTALL REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY
Using SST, install the companion flange to the drive pinion.
Note
Apply grease to the threads and tip of the SST center bolt before use.
Coat the threads of a new drive pinion nut with hypoid gear oil LSD.
Using SST, hold the flange.
Using a socket wrench (30 mm) and torque wrench, gradually tighten the drive pinion nut within the adjustment range of the differential drive pinion preload.
INSPECT AND ADJUST DIFFERENTIAL DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the drive pinion.
| Preload (at starting) |
|---|
| New bearing |
| 1.01 to 1.60 N*m (11 to 16 kgf*cm, 9 to 14 in.*lbf) |
| Reused bearing |
| 0.52 to 0.81 N*m (6 to 8 kgf*cm, 5 to 7 in.*lbf) |
If the preload is less than the specified minimum value, check the preload while retightening the drive pinion nut by 5 to 10° to adjust it into the specified range.
If the preload is less than the specified minimum value even when the tightening torque of the drive pinion nut is greater than the specified maximum value, loosen the nut and check that the threads of the drive pinion nut and drive pinion are not stripped.
If the threads are not stripped, replace the bearing spacer. Apply hypoid gear oil LSD to the threads of the drive pinion and repeat the procedure.
INSTALL REAR DRIVE PINION NUT
Using a chisel and hammer, stake the drive pinion nut.
INSTALL PROPELLER SHAFT ASSEMBLY (for Super Long Wheelbase)
Remove the SST from the extension housing.
Install the propeller with center bearing shaft assembly in the extension housing.
Install the center support bearing assembly No.1, and temporarily tighten the 2 bolts.
Align the matchmarks on the propeller shaft flange and differential flange.
Install the propeller shaft assembly with the 4 nuts, 4 bolts and 4 washers.
Check that the center line of the bracket is at right angles to the shaft axial direction.
Adjust the center support bearing assembly No.1.
Tech Tips
With the vehicle unladen, adjust the center support bearing No.1 to maintain the angles, as shown.
In the same conditions, check the center line in the axial direction. Adjust the bearing if necessary.
The center bearing center line and center bearing housing center line must be adjusted to within -1.0 to 1.0 mm (-0.0394 to 0.0394 in.) of each other in the vehicle's longitudinal direction with the vehicle unladen.
Tighten the 2 bolts.

Note
Excessively large or small amounts of oil may cause trouble.
After replacing oil, drive the vehicle and check the oil level.
Tech Tips
If necessary, fill the rear differential carrier with hypoid gear oil.
Check for oil leakage when the oil level is low.
