14. w/o DIFFERENTIAL LOCK:
INSTALL ADJUSTING NUTS
Install the 2 adjusting nuts on the carrier, making sure the nuts
are threaded properly.
15. w/o DIFFERENTIAL LOCK: INSTALL BEARING CAPS
Align the matchmarks on the cap and carrier. Screw in the 2
bearing cap bolts 2 or 3 turns and press down the bearing cap
by hand.
HINT:
If the bearing cap does not fit tightly on the carrier , the adjusting
nuts are not threaded properly.
Reinstall the adjusting nuts if necessary.
16. w/o DIFFERENTIAL LOCK: ADJUST SIDE BEARING PRELOAD
(a) Torque the 4 bearing cap bolts to the specified torque, then loosen them to the point where the adjusting nuts
can be turned by SST.
SST 09504−00011
Torque:78 N·m (800 kgf·cm, 58 ft·lbf)
(b) Fully tighten the 4 bearing cap bolts by hand.
(c) Using the SST, torque the adjusting nut on the ring gear side until the ring has a backlash of about 0.2 mm (0.008
in.).
(d) With turning the ring gear, use the SST to fully tighten the
adjusting nut on the drive pinion side. After the bearings
as settled, loosen the adjusting nut on the drive pinion
side.
(e) Place a dial indicator on the top of the adjusting nut on the ring gear side.
(f) Adjust the side bearing for zero preload by tightening the
other adjusting nut until the pointer on the indicator be-
gins to move.

nuts equal amounts. For example, loosen the nut on the left
side one notch and torque the nut on the right side one notch.

Total preload (at starting):
Drive pinion preload plus
w/o Differential lock
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
w/ Differential lock
0.3− 0.7 N·m (3 − 7 kgf·cm, 2.6 − 6.1 in.·lbf)
18. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION
(a) Coat 3 or 4 teeth at 3 different positions on the ring gear
with red lead.
(b) Turn the companion flange, pin both directions to inspect the ring gear for proper tooth contact.

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.

DIFFERENTIAL LOCKING SYSTEM
ON−VEHICLE INSPECTION
1. INSPECT DIFFERENTIAL LOCK SYSTEM
(a) Inspect the indicator lights.
Check that the indicator lights (front side and rear side)
light up for approx. 1 second when the ignition switch is
turned ON.
(b) Inspect the differential lock operation. (1) Jack up the vehicle then start the engine.
(2) Put the transfer shift lever on the L position.
(3) When the Diff. lock control switch is set to the RR
position, the indicator light (rear side) is turned on.
Differential lock is applied to the rear wheel at this
time.
HINT:
If the gears of the differential lock system are not meshed, the
indicator light remains blinking, so rotate the tires to mesh the
gear.
(4) When the Diff. lock control switch is at the OFF posi-
tion, the indicator light goes off.
Differential lock is released for the rear wheel at this
time.
(5) When the Diff. lock control switch is set to the FR/ RR position, the indicator lights (front side and rear
side) are turned on.
Differential lock is applied to both the front wheels
and rear wheels at this time.
