(d) Adjust the drive pinion preload by tightening the compan-
ion flange nut.
Using SST to hold the flange, tighten the nut.
SST 09330−00021
NOTICE:
Coat the nut and screw of the drive pinion with gear oil. As
there is no spacer, tighten a little at a time, being careful not
to overtighten.
(e) Using a torque wrench, measure the preload. Preload (at starting):
New bearing
1.3 − 2.0 N·m (13 − 20 kgf·cm, 11.3 − 17.4 in.·lbf)
Reused bearing
0.7 − 1.0 N·m (7 − 10 kgf·cm, 6.1 − 8.7 in.·lbf)
HINT:
Measure the total preload after first turning the bearing clock-
wise and counterclockwise several times to make the bearing
smooth.
10. w/o DIFFERENTIAL LOCK: INSTALL DIFFERENTIAL CASE IN CARRIER
(a) Place the 2 bearing outer races on their respective bear- ings. Make sure that the left and right outer races are not
interchanged.
(b) Install the case in the carrier.
HINT:
Make sure that there is backlash between the ring gear and
drive pinion.
11. w/ DIFFERENTIAL LOCK: INSTALL DIFFERENTIAL CASE IN CARRIER
(a) Place the 2 bearing outer races on their respective bear- ings. Make sure that the left and right races are not inter-
changed.
(b) Install the assembled plate washer onto the side bearing.
(c) Install the differential case in the carrier.
(d) Make the plate washer and bearing smooth by tapping on
the ring gear with a plastic hammer.
HINT:
If it is difficult to install the differential case into the carrier, re-
place the plate washer with a thinner one.
However, select a plate washer that allows no clearance be-
tween it and the carrier.

22. INSTALL OIL SEAL
(a) Using SST and a hammer, install a new oil seal, as shown.
SST 09214−76011
Oil seal drive in depth: 1.0 mm (0.039 in.)
(b) Apply MP grease to the oil seal lip.
23. INSTALL COMPANION FLANGE
(a) Install the companion flange with SST. SST 09550 −30010 (09951 −03010, 09953 −03010,
09954 −03010, 09955 −03030, 09956−03020)
(b) Install the plate washer and a new nut.
HINT:
Coat the threads of a new nut with gear oil.
(c) Using SST to hold the flange, tighten the nut. SST 09330−00021
Torque: 245 N·m (2,500 kgf·cm, 181 ft·lbf)
24. ADJUST DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the backlash
between the drive pinion and ring gear. Preload (at starting):
New bearing
1.3 − 2.0 N·m (13 − 20 kgf·cm, 11.3 − 17.4 in.·lbf)
Reused bearing
0.7 − 1.0 N·m (7 − 10 kgf·cm, 6.1 − 8.7 in.·lbf)
If the preload is greater than the specification, replace the bear-
ing spacer.
If the preload is less than the specification, retighten the nut a
little at a time 13 N·m (130 kgf·cm, 9 ft·lbf) until the specified pre-
load is reached. Maximum torque: 441 N·m (4,500 kgf·cm, 326 ft·lbf)
If the maximum torque is exceeded while retightening the nut,
replace the bearing spacer and repeat the preload procedure.
Do not back off the pinion nut to reduce the preload.

INSTALLATION
1. INSTALL FRONT ACTUATOR
(a) Check that the outermost rack tooth of the shift fork is
virtually above the center line of the actuator installation
hole.
(b) Using a dry cell battery, alig n the matchmark on the pinion
with the center line of the actuator.
NOTICE:
If the pinion of the actuator is not in the specified
place, the actuator is difficult to be installed.
Do not supply the battery positive voltage between
terminals.
If the matchmark comes to the extension limit of the
rotation, do not electrify moreover.
(c) Install a new O−ring to the actuator.
(d) Apply a light coat of gear oil on the O −ring.
(e) Apply MP grease to the gear part of the actuator.
(f) Install the actuator to the differential with the 2 nuts and bolt, so that the outermost rack tooth of the shift fork will
fit matchmark of the pinion of the actuator.
HINT:
Do not damage the O −ring of the actuator.
Torque: 26 N·m (270 kgf·cm, 20 ft·lbf)
