Inspection
AXLE SHAFT
Check axle shaft for straightness, cracks, damage, wear or distor-
tion. Replace if necessary.
BEARING CAGE
Check bearing cage for deformation or cracks. Replace if neces-
sary.
REAR AXLE HOUSING
Check rear axle housing for yield, deformation or cracks. Replace
if necessary.
Installation
1. Press new wheel bearing until it bottoms end face of bearing
cage.
Always press outer race of wheel bearing during installation.
2. Press new grease seal until it bottoms end face of bearing
cage.
After installing new grease seal, coat sealing lip with multi-
purpose grease.
3. Install bearing spacer with chamfer side facing axle shaft
¯ange.
4. Install caliper adapter and baffle plate to bearing cage.
5. Press axle shaft into inner race of wheel bearing.
Be careful not to damage or deform grease seal.

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.

Removal and Installation
+Support axle and suspension components with a suitable jack
and block.
+Disconnect brake hydraulic line and parking brake cables at
back plates.
CAUTION:
+Use ¯are nut wrench when removing or installing brake
tubes.
+Before removing the rear suspension assembly, discon-
nect the ABS wheel sensor from the assembly. Then move
it away from the rear suspension assembly. Failure to do
so may result in damage to the sensor wires and the sen-
sor becoming inoperative.
+Remove stabilizer bar from body.
+Remove upper links and lower links from body.
+Remove panhard rod from body.
+Disconnect rear end of propeller shaft. Refer to PD section.
+Remove upper end nuts of shock absorber.

Final tightening for rubber parts requires to be carried out
under unladen condition with tires on ground.
Coil Spring and Shock Absorber
REMOVAL AND INSTALLATION
Refer to ``Removal and Installation'', ``REAR SUSPENSION'',
RA-13.
When installing coil spring, pay attention to its direction.
Be sure spring rubber seat is not twisted and has not slipped
off when installing coil spring.
INSPECTION
+Check coil spring for yield, deformation or cracks.
+Check shock absorber for oil leakage, cracks or deformation.
+Check all rubber parts for wear, cracks or deformation. Replace
if necessary.
Upper Link, Lower Link and Panhard Rod
INSPECTION
Check for cracks, distortion or other damage. Replace if necessary.
BUSHING REPLACEMENT
Check for cracks or other damage. Replace with suitable tool if
necessary.
+Remove bushing with suitable tool.
When installing bushing, apply a coat of 1% soapy water to
outer wall of bushing.
Always install new bushing.
Do not tap end face of bushing directly with a hammer.

INSTALLATION
When installing each link, pay attention to direction of nuts
and bolts.
When installing each rubber part, ®nal tightening must be car-
ried out under unladen condition with tires on ground.
Stabilizer Bar
REMOVAL AND INSTALLATION
+When removing and installing stabilizer bar, ®x portion A.
+Install stabilizer bar with ball joint socket properly placed.

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.
