When the following replacement, removal and in-
stallation are performed, be sure to perform center-
ing of the steering angle sensor and zero point
setting of the yaw rate & G sensor.

•Steering angle sensor
•Yaw rate & lateral G sensor
•Steering wheel parts (Including airbag)
•Suspension parts
•Wheel alignment adjustment
1) Park the vehicle straight on a level surface. (En-
gine operation in the “P” or “N” range)
2) Check that steering wheel is positioned at the
center. (When the center position is not correct, ad-
just the wheel alignment.)
3) Set the Subaru Select Monitor to the vehicle,
and select {Set up mode for Neutral of Steering An-
gle Sensor & Lateral G Sensor 0 point} in the
“Function check sequence” screen. (Follow the
procedures shown in the display.)
4) On the “Brake Control System” display screen,
select {Current Data Display & Save}, and check
that the steering angle sensor shows “0 deg”.
5) When the “0 deg” is not displayed, repeat the
above steps and check that the “0 deg” is dis-
played.
6) Drive the vehicle for 10 minutes, and check that
the ABS and VDC warning light is not illuminated.
7) Check that there is no unnecessary VDC opera-
tion or steering control loss. If there is a problem,
repeat the steps above.

PERIODIC MAINTENANCE SERVICES
17.Suspension
A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out
along the shaft. If relative movement is observed
between the brake disc cover (A) and end of front
arm (D), ball joint (C) may be excessively worn.
3) Grasp the end of front arm and move it up and
down. Relative movement (A) between the housing
(D) and front arm (C) boss indicates ball joint (B)
may be excessively worn.
4) If relative movement is observed in the step 2),
3), remove and inspect the ball joint. If the free play
exceeds standard value, replace the ball joint.

5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the front arm. Arm.> Also, measure the free play of the ball joint.

(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with a
new ball joint.
NOTE:
When the front arm ball joint has been removed or
replaced, check the toe-in of front wheel. If the front
wheel toe-in is not at specified value, adjust the
toe-in.
2. FRONT, REAR SUSPENSION BUSHING
Apply pressure with tire lever etc, and inspect the
bushing for wear or crack. Replace the bushings
and the arm assembly or link assembly if there is
wear or there are cracks.
3. WHEEL ARCH HEIGHT
1) Unload the cargo and set the vehicle in curb
weight (empty) condition.
2) Check the wheel arch height of the front and rear
suspensions to ensure that they are within speci-
fied values.
3) When the wheel arch height is out of standard,
visually inspect following components and replace
deformed parts.
•Suspension components [Front strut assembly
and rear shock absorber assembly]
•Parts connecting suspension and body
4) When no components are deformed, adjust
wheel arch height by replacing coil spring in the
suspension whose wheel arch height is out of stan-
dard. RS-7, Wheel Alignment.>
