Precautions
lWhen installing each rubber part, final tightening must
be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment.
lDo not jack up at the trailing arm and lateral link.
lAlways torque brake lines when installing.

Rear Axle and Rear Suspension Parts
Check axle and suspension parts for excessive play, wear or
damage.
lShake each rear wheel to check for excessive play.
lRetighten all nuts and bolts to the specified torque.
Tightening torque:
Refer to REAR SUSPENSION (RA-9).
lCheck shock absorber for oil leakage or other damage.
Rear Wheel Bearing
lCheck axial end play.
Axial end play:
0.00 mm (0.0000 in)

Rear Wheel Alignment
PRELIMINARY INSPECTION
Make following checks. Adjust, repair or replace if necessary.
lCheck tires for wear and for improper inflation.
lCheck rear wheel bearings for excessive play.
lCheck wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout: Refer to SDS in FA section.
lCheck that rear shock absorber functions correctly.
lCheck rear axle and rear suspension parts for excessive
play.
lCheck vehicle posture (Unladen*).
*: Fuel, radiator and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
CAMBER
Camber is preset at factory and cannot be adjusted.
Camber:
Refer to SDS (RA-14).
lIf the camber is not within specification, inspect and replace
any damaged or worn rear suspension parts.
TOE-IN
Toe-in is preset at factory and cannot be adjusted.
Measure toe-in using following procedure. If out of
specification, inspect and replace any damaged or worn rear
suspension parts.
WARNING:
lAlways perform following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before
pushing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires
at the same height of hub center. This mark is a measuring
point.
4. Measure distance ªAº (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Never
push vehicle backward.
6. Measure distance ªBº (front side).
Total toe-in:
Refer to SDS, RA-14.

REMOVAL
CAUTION:
lBefore removing the rear wheel hub assembly, discon-
nect the ABS wheel sensor from the assembly. Then
move it away from the hub assembly. Failure to do so
may result in damage to the sensor wires and the sen-
sor becoming inoperative.
lWheel hub bearing does not require maintenance. If any
of the following symptoms are noted, replace wheel hub
bearing assembly.
lGrowling noise is emitted from wheel hub bearing during
operation.
lWheel hub bearing drags or turns roughly. This occurs when
turning hub by hand after bearing lock nut is tightened to
specified torque.

4. Remove wheel hub bearing from spindle.
Brake hose does not need to be disconnected from brake
caliper.
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop out.
Make sure brake hose is not twisted.
INSTALLATION
lInstall wheel hub bearing.
lTighten wheel bearing lock nut.
Before tightening, apply oil to threaded portion of rear spindle

Removal and Installation
CAUTION:
lBefore removing the rear suspension assembly, discon-
nect the ABS wheel sensor and headlamp leveling sen-
sor from the assembly. Failure to do so may result in
damage to the sensor wires and the sensor becoming
inoperative.
lRemove suspension assembly.
1. Disconnect parking brake cable from caliper and remove
brake caliper and rotor.
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop out.
Make sure brake hose is not twisted.
2. Using a transmission jack, raise torsion beam a little, and
remove nuts and bolts from the trailing arm, shock absorber
assembly (lower side) and lateral link.
3. Lower transmission jack, and remove suspension.
4. Remove shock absorber assembly.
lInstall suspension assembly.
CAUTION:
Refill with new brake fluid ªDOT 4º.
Never reuse drained brake fluid.
lAfter installation of the suspension assembly the head-
lamp leveling sensor has to be recalibrated. Refer to EL
section (models equipped with xenon headlamps only).
1. Attach torsion beam, at trailing arm and lateral link, to
vehicle. Do not tighten bolts at this time.
2. Using a transmission jack, place lateral link and control rod
horizontally against torsion beam. Tighten lateral link on
vehicle.
3. Attach shock absorber assembly to vehicle. Then tighten the
lower side of shock absorber assembly.
4. Lower torsion beam to fully extended position. Remove
transmission jack and tighten torsion beam, at trailing arm, to
specified torque.Refer to RA-9.
5. Install ABS-wheel sensor.
