HINT:
First fit a washer with the same thickness as the washer which
was removed, then after checking the tooth contact pattern, re-
place the washer with one of a different thickness if necessary.
6. INSTALL DRIVE PINION REAR BEARING
Using SST and a press, install the rear bearing onto the drive
pinion.
SST 09506−35010
7. TEMPORARILY ADJUST DRIVE PINION PRELOAD
(a) Install the drive pinion and front bearing.
HINT:
Assemble the spacer, washers and oil seal after adjusting the
gear contact pattern.
(b) Using SST, install the companion flange.
SST 09950−30010
(c) Coat the threads of the nut with hypoid gear oil.
(d) Adjust the drive pinion preload by tightening the compan-
ion flange nut.
Using SST to hold the flange, torque the nut.
SST 09330−00021
NOTICE:
As there is no spacer, tighten the nut a little at a time, being
careful not to overtighten it.
(e) Using a torque wrench, measure the preload.
Preload (at starting):
New bearing:
1.0 − 1.6 N·m (10 − 16 kgf·cm, 8.7 − 13.9 in.·lbf)
Reused bearing:
0.5 − 0.8 N·m (5 − 8 kgf·cm, 4.3 − 6.9 in.·lbf)

8. INSTALL DIFFERENTIAL CASE IN CARRIER
(a) Place the bearing outer races on their respective bear-
ings. Make sure the left and right races are not inter-
changed.
(b) Install the differential case in the carrier.
9. ADJUST RING GEAR BACKLASH
(a) Only install the plate washer on the ring gear back side.
HINT:
Makes that the ring gear has a backlash.
(b) Tap on the ring gear with a plastic hammer so that the
washer fit to the bearing.
(c) Using a dial indicator, measure the side gear backlash
with holding one pinion gear toward the differential case.
Backlash (reference):
2WD: 0.08 − 0.13 mm (0.0031 − 0.0051 in.)
4WD: 0.13 − 0.18 mm (0.0051 − 0.0071 in.)
(d) Select a plate washer for back side ring gear, using the
backlash as reference (See page SA−145).
(e) Select a ring gear teeth side plate washer of a thickness
which eliminates any clearance between the outer race
and case.

(f) Remove the plate washers and differential case.
(g) Install the plate washer into the ring gear back side of the
carrier.
(h) Place the other plate washer onto the differential case to-
gether with the outer race, and install the differential case
with the outer race into the carrier.

4WD: 0.13 − 0.18 mm (0.0051 − 0.0071 in.)
(k) If the backlash not within specification, adjust by either in-
creasing or decreasing the thickness of washers on both
sides by an equal amount.
HINT:
There should be no clearance between the plate washer
and case.
Make sure that there is ring gear backlash.
10. ADJUST SIDE BEARING PRELOAD
(a) After adjustment with the backlash as reference, remove
the ring gear teeth side plate washer and measure the
thickness.
(b) Install a new washer of 0.06 − 0.09 mm (0.00024 − 0.0035
in.) thicker than the washer removed.
HINT:
Select a washer which can be pressed in 2/3 of the way by fin-
ger.
(c) Using a plastic hammer, tap in the plate washer.
(d) Recheck the ring gear backlash.
Backlash:
2WD: 0.08 − 0.13 mm (0.0031 − 0.0051 in.)
4WD: 0.13 − 0.18 mm (0.0051 − 0.0071 in.)
(e) If the backlash is not within specification, adjust by either
increasing or decreasing the thickness washers on both
sides by equal amount.
HINT:
The backlash will change by about 0.20 mm (0.0008 in.) with
every 0.03 mm (0.0012 in.) change in the side washer.
