Install 2 side gears, 2 pinion gears, 2 rear No. 1 differential side gear thrust washers, 2 pinion gear thrust washers and the pinion shaft in the differential case.
Align the holes of the differential case and pinion shaft.
Measure the side gear backlash.
Using a dial indicator, measure the side gear backlash while holding one pinion gear toward the differential case.
0.05 to 0.20 mm (0.00197 to 0.00787 in.)
If the backlash is not as specified, install 2 side gear thrust washers with different thicknesses.
Using a pin punch and hammer, tap in the straight pin through the differential case and hole of the pinion shaft.
Stake the differential case.
2.INSTALL DIFFERENTIAL RING GEAR
Clean the contact surfaces of the differential case and differential ring gear.
Heat the differential ring gear in boiling water that is approximately 100°C (212°F).
Carefully remove the differential ring gear from the boiling water.
Use thick gloves to protect your hands as the differential ring gear is hot.
| *a | Matchmark |
After the moisture on the differential ring gear has completely evaporated, quickly align the matchmarks on the differential ring gear and differential case and install the differential ring gear to the differential case.
After the ring gear cools down sufficiently, apply adhesive to the 12 bolts and Temporarily install them.
Toyota Genuine Adhesive 1360K, Three Bond1360K or equivalent
Diametrically tighten the 12 bolts uniformly in several passes.

4.INSPECT DIFFERENTIAL RING GEAR RUNOUT
Install the differential case on the rear differential carrier, and install the 2 shims so that there is no play in the bearing.
Install the 2 differential bearing caps with the 4 bolts.
| *a | 98 mm (3.86 in.) |
Using a dial indicator, measure the runout of the differential ring gear.
0.07 mm (0.00276 in.)
Remove the 2 differential bearing caps, 2 shims and differential case assembly.

5.INSTALL DIFFERENTIAL OIL STORAGE RING
| *1 | Differential Oil Storage Ring |
Using SST and a hammer, tap in the differential oil storage ring.
Be careful not to damage the differential oil storage ring.
41201B
6.INSTALL REAR DRIVE PINION FRONT BEARING (OUTER)
| *1 | Rear Drive Pinion Front Bearing (Outer) |
Using SST and a press, press the rear drive pinion front bearing (outer) into the rear differential carrier.
41201A
7.INSTALL REAR DRIVE PINION REAR BEARING (OUTER)
| *1 | Rear Drive Pinion Rear Bearing (Outer) |
Using SST and a press, press the adjust shim and rear drive pinion rear bearing (outer) into the rear differential carrier.
First, install an adjust shim that has the same thickness as the removed adjust shim. After checking the tooth contact pattern, replace the adjust shim with one of a different thickness if necessary.
41201A
8.INSTALL REAR DRIVE PINION REAR BEARING (INNER)
Using SST and a press, press the rear drive pinion rear bearing (inner) onto the differential drive pinion.
9.ADJUST DIFFERENTIAL DRIVE PINION PRELOAD
Install the differential drive pinion and rear drive pinion front bearing (inner).
Install the rear differential drive pinion bearing spacer and rear differential carrier oil seal after adjusting the gear contact pattern.
Install the rear differential drive pinion oil slinger.
| *a | Turn |
| *b | Hold |
Using SST, install the rear drive pinion companion flange sub-assembly with dust deflector.
Before using SST (center bolt), apply hypoid gear oil to its threads and tip.
Adjust the drive pinion preload by tightening the drive pinion nut.
Using SST to hold the companion flange in place, slowly tighten the nut within the drive pinion preload adjustment range so that it reaches the specified drive pinion preload (at Starting).
457 N*m (4660 kgf*cm, 337 ft.*lbf) or less
As there is no spacer, tighten a little at a time. Be careful not to overtighten the nut.
Apply hypoid gear oil LSD to the drive pinion thread and nut seat face.
Using a torque wrench, measure the preload.
| Bearing | Preload |
|---|---|
| New bearing | 1.11 to 3.88 N*m (12 to 39 kgf*cm, 10 to 34 in.*lbf) |
| Reused bearing | 1.34 to 2.63 N*m (14 to 26 kgf*cm, 12 to 23 in.*lbf) |
For a more accurate measurement, rotate the bearing forward and backward several times before measuring.
Record the differential drive pinion preload for the total preload measurement.
10.INSTALL DIFFERENTIAL CASE ASSEMBLY
Place the 2 rear differential case bearings (outer) to their respective bearings.
Make sure the right and left races are not interchanged.
11.ADJUST DIFFERENTIAL RING GEAR BACKLASH
Install the shim to the RH side (teeth side).
Make sure that the differential ring gear has backlash.
Using a dial indicator, while holding the companion flange, measure the ring gear backlash.
0.10 to 0.20 mm (0.00394 to 0.00787 in.)
Refer to the backlash when selecting a shim for the RH side (teeth side).
Select a shim for the LH side (back side) so that there is no gap between the rear differential case bearing (outer) and differential case.
Using a plastic-faced hammer, install the shim to the LH side (back side).
Using a dial indicator, adjust the ring gear backlash until it is within the specification.
0.10 to 0.20 mm (0.00394 to 0.00787 in.)
If the backlash is not within the specification, adjust it by either increasing or decreasing the thickness of the shims on both sides by an equal amount.
There should be no clearance between the shim and case.
Make sure that there is ring gear backlash.
12.ADJUST SIDE BEARING PRELOAD
After adjusting the backlash of the differential ring gear, remove the shim from the LH side (back side).
Using a micrometer, measure the thickness of the shim.
Using the backlash as a reference, select a new shim that is 0.05 to 0.20 mm (0.00197 to 0.00787 in.) thicker than the removed shim and, using a plastic-faced hammer, tap it in so that it fits against the bearing.
Select a shim which can be pressed in 2/3 of the full amount with your finger.
Recheck the ring gear backlash.
0.10 to 0.20 mm (0.00394 to 0.00787 in.)
If the backlash is not within the specification, adjust it by either increasing or decreasing the thickness of the shims on both sides by an equal amount.
An approximately 0.02 mm (0.000787 in.) change in each shim results in a 0.03 mm (0.00118 in.) change in the backlash.
