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.

(g) Using the SST, torque the adjusting nut 1−1.5 notches
from the zero preload position.
(h) Using a dial indicator, adjust the ring gear backlash until it is within the specification.
Backlash: 0.15 − 0.20 mm (0.0059−0.0079 in.)
HINT:
The backlash is adjusted by turning the left and right adjusting
nuts equal amounts. For example, loosen the nut on the left
side one notch and torque the nut on the right side one notch.
(i) Torque the 4 bearing cap bolts. Torque:78 N·m (800 kgf·cm, 58 ft·lbf)
(j) Recheck the ring gear backlash. Backlash: 0.15 − 0.20 mm (0.0059−0.0079 in.)
17. MEASURE TOTAL PRELOAD
Using a torque wrench, measure the preload.
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.

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)
