Knuckle Flange'').
+Remove axle shaft.
Refer to RA section (``REAR AXLE'').
+Remove front and rear ®nal drive mounting bolts.
CAUTION:
+Be careful not to damage spline, sleeve yoke and front oil
seal when removing propeller shaft.
+Before removing the ®nal drive assembly or rear axle
assembly, disconnect the ABS sensor harness connector

Malfunction is in system other than differential lock con-
trol unit, speed sensor. Check and correct.
Turn differential lock switch OFF while driving vehicle at
speed less than 7 km/h (4 MPH) or when stopping.

When speed sensor functions, differential lock control
unit functions improperly.
Differential lock control unit is functioning properly.Check differential lock control unit.
Unit check
1. Ensure that wiring to differential lock control unit is correct and
that the unit is properly connected to power supply.
2. Place vehicle on a safety stand properly. Ensure that the front
and rear wheels rotate freely.
3. Check output voltage of differential lock at solenoid-2 connec-
tor.

Removal
CAUTION:
+Before removing the rear axle, disconnect the ABS wheel
sensor from the assembly. Then move it away from the
axle. Failure to do so may result in damage to the sensor
wires and the sensor becoming inoperative.
+Wheel bearing does not require maintenance.
+If growling noise is emitted from wheel bearing during
operation, replace wheel bearing assembly.
+If the wheel bearing assembly is removed, it must be renewed.
The old assembly must not be re-used.
1. Disconnect parking brake cable and brake tube.
2. Remove nuts securing wheel bearing cage with baffle plate.
3. Draw out axle shaft with Tool.
When drawing out axle shaft, be careful not to damage oil seal.
4. Remove O-ring.
5. Remove oil seal with a screwdriver.
Do not reuse oil seal once it is removed.
Always install new one.
6. Remove ABS sensor rotor. Ð Models with ABS Ð

6. Install a new wheel bearing lock washer.
7. Tighten wheel bearing lock nut to speci®ed torque.
: 441 - 490 Nzm (45 - 50 kg-m, 325 - 362 ft-lb)
Be sure to bend bearing lock washer up.
8. Check wheel bearing preload.
a. Turn bearing cage (with respect to axle shaft) two or three
times. It must turn smoothly.
b. Attach spring gauge to bearing cage bolt (as shown at left) and
pull it at a speed of 10 rpm to measure preload.
Spring gauge indication:
8.8 - 42.2 N (0.9 - 4.3 kg, 2.0 - 9.5 lb)
9. Install new oil seal to rear axle housing using a suitable tool.
After installing new oil seal, coat sealing lip with multi-purpose
grease.
10. Install new O-ring to rear axle housing.
11. Press ABS sensor rotor onto axle shaft until it contacts wheel
bearing lock nut.
12. Install axle shafts in rear axle housing.
Be careful not to damage oil seal.

System Components
Roll rigidity is increased by activating the stabilizer function (turning the stabilizer ON) on good roads. On rough
roads, deactivating the stabilizer function (turning the stabilizer OFF) reduces stabilizer swing-back behavior.
As a result, the stabilizer release device serves to increase driving capability and riding comfort on rough roads.
The stabilizer release device is electrically activated (turned ON) or deactivated (turned OFF) by the stabilizer
switch in the driver's compartment.
System Description
CONTROL UNIT
The stabilizer control unit controls the actuator motor using the
stabilizer switch and a signal sent from the vehicle speed sensor.
When vehicle speed exceeds 20 km/h (12 MPH), the stabilizer
control unit maintains the clutch cylinder position and activates the
stabilizer function, regardless of the position of the stabilizer switch.
The system is provided with a timer function to cut the actuator
activating power output in about 15 seconds, in consideration of a
possible system abnormality.
ACTUATOR
The actuator motor is turned on by a signal sent from the control
unit. When the motor operates, the cable moves to activate the
stopper pin at the end of the cable.
CLUTCH CYLINDER
The stopper pin (at the end of the cable) moves in and out of the
cylinder (toward the piston rod or away from the piston rod) to turn
the stabilizer ON or OFF.
