(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: 196 N·m (2,000 kgf·cm, 145 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:
0.9 − 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)
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 with a torque of 13 N·m (130 kgf·cm, 9 ft·lbf) until
the specified preload is reached. Maximum torque: 343 N·m (3,500 kgf·cm, 253 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.
25. RECHECK RING GEAR BACKLASH
26. RECHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION
27. CHECK RUNOUT OF COMPANION FLANGE
28. STAKE DRIVE PINION NUT
29. INSTALL ADJUSTING NUT LOCKS
(a) Install 2 new nut locks on the bearing caps. Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(b) After tightening bolts, bend the nut locks.

30. w/ DIFFERENTIAL LOCK:
INSTALL SHIFT FORK SHAFT
(a) Apply MP grease onto the outer circuit of the fork shaft.
(b) Install the fork shaft to match the hole of the shift fork and
that of the shift fork shaft.
(c) Remove any FIPG material and be careful not to drop oil on the contacting surface of the differential carrier and
shaft retainer.
(d) Apply FIPG to the carrier, as shown. FIPG: Part No. 08826−00090, THREE BOND 1281 or
equivalent
HINT:
Install the shaft retainer within 10 minutes after applying FIPG.
(e) Clean the threads of the bolts and retainer bolts holes with
toluene or trichlorethylene.
(f) Apply adhesive to 2 or 3 threads of the mount bolt end. Adhesive: Part No. 08833 −00080, THREE BOND 1344,
LOCTITE 242 or equivalent
(g) Tighten the shaft retainer with the 2 bolts. Torque: 24 N·m (240 kgf·cm, 17 ft·lbf)
(h) Using a pin punch and hummer, install the slotted spring pin to the shift fork.
(i) Shift the fork deeply and keep the differential lock condi- tion.

(j) Install the ball, compression spring and spring seat.
(k) Clean the threads of 2 plugs and plug holes with toluene
or trichloroethylene.
(l) Apply adhesive to the plug threads. Adhesive: Part No. 08833 −00080, THREE BOND 1344,
LOCTITE 242 or equivalent
(m) Using a hexagon wrench, install and tighten the screw
plugs.
Torque: 22 N·m (220 kgf·cm, 16 ft·lbf)
31. w/ DIFFERENTIAL LOCK: MEASURE DISTANCE BETWEEN SLEEVE AND DIF-
FERENTIAL CASE END SIDE
Measure distance between the sleeve and tip of the differential
case when differential is free and locked. Standard distance:
LOCK: 17.44 − 18.86 mm (0.6866 − 0.7425 in.)
FREE: 32.40 − 33.90 mm (1.2756 − 1.3346 in.)
32. w/ DIFFERENTIAL LOCK: INSTALL INDICATOR SWITCH
Install the indicator switch with a new gasket. Torque: 40 N·m (410 kgf·cm, 30 ft·lbf)
33. w/ DIFFERENTIAL LOCK: INSTALL ACTUATOR
(a) Check that the outermost rack tooth of the shift fork is virtually above the center line of the actuator installation
hole.

(b) Ensure that the matchmarks of the pinion of the actuator
is in the extent between zero and 5 degrees clockwise
above the center line of the actuator.
If the matchmarks is not in this extent, rotate the pinion to be
matched. Do not supply the battery positive voltage directly be-
tween terminals. If the matchmarks come 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.
(f) Insert the actuator so that the long hole on the actuator side fits with the knock pin on the carrier side.
HINT:
Do not damage the O −ring of the actuator.
(g) Align the actuator with the long hole and rotate the actua-
tor counterclockwise when the knock pin reaches the
right−hand side.
(h) Install the actuator to the differential carrier with the bolt so that the outermost rack tooth of the shift fork will fit the
matchmarks of the pinion of the actuator.
Torque: 26 N·m (270 kgf·cm, 20 ft·lbf)

INSTALLATION
Installation is in the reverse order of removal (see page SA−27).
HINT:
w/ differential lock:
Before installation, check differential lock operation connecting the connector of the actuator to the
connector of the vehicle side.
w/ differential lock:
Before installation, check that the sleeves on work with switching over the differential lock control
switch.
After checking, lock the front differential.
After installation, fill the differential with gear oil (See page SA−27).
w/ differential lock:
After installation, check that the bleeder plug at the point of the bleeder tu\
be (inside of the engine room)
is not damaged or worn.
