Suspension
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.>

4. WHEEL ALIGNMENT OF FRONT SUS-
PENSION
1) Check the alignment of front suspension to en-
sure that following items conform to standard val-
ues.
•Toe-in
•Camber
•Caster
•Steering angle

2) When the caster angle does not conform to ref-
erence obviously, visually inspect the following
components and replace deformed parts.
•Suspension components [Strut assembly, cross-
member, front arm, etc.]
•Parts connecting suspension and body
3) When the toe-in and camber are out of standard
value, adjust them so that they conform to standard
value.
4) When the right-and-left turning angles of tire are
out of standard, adjust to standard value.
5. WHEEL ALIGNMENT OF REAR SUS-
PENSION
1) Check the alignment of rear suspension to en-
sure that following items are within standard val-
ues.
•Toe-in
•Camber
•Thrust angle

2) When the camber angle does not conform to
standard value, visually inspect the following com-
ponents. If the deformation is observed, replace the
damaged parts.
•Suspension components [Shock absorber, rear
upper arm, front lateral link, rear lateral link, rear
trailing link, sub frame]
•Parts connecting suspension and body
3) When the toe-in and thrust angle are out of stan-
dard value, adjust them so that they conform to
standard value.
6. OIL LEAKAGE OF STRUT AND SHOCK
ABSORBER
Visually inspect the front strut and rear shock ab-
sorber for oil leakage. Replace the front strut and
rear shock absorber if oil leaks excessively.
7. TIGHTNESS OF BOLTS AND NUTS
Check the bolts and nuts for looseness. Retighten
the bolts and nuts to specified torque. If the self-
locking nuts and bolts are removed, replace them
with new ones.
•Front suspension

•Rear suspension

8. DAMAGE TO SUSPENSION PARTS
Check the following parts and the fastening portion
of the vehicle body for deformation or excessive
rusting which impairs the suspension. If necessary,
replace the damaged parts with new ones. If minor
rust formation, pitting, etc. are noted, remove the
rust and take rust prevention measure.
•Front suspension
•Front arm
•Crossmember
•Strut
•Rear suspension
•Upper arm
•Front lateral link
•Rear lateral link
•Rear trailing link
•Rear sub frame
•Shock absorber
•In the area where salt is sprayed to melt snow on
a road in winter, check suspension parts for dam-
age caused by rust every 12 months after lapse of
60 months. Take rust prevention measures as re-
quired.

Tire Rotation
PERIODIC MAINTENANCE SERVICES
20.Tire Rotation
A: INSPECTION
1) When the tread has worn down to 1.8 mm (2/
0.071 in) or the wear indicator appears across the
tread, replace the tire. (Replace the right and left
tire as a set.)
2) If the tire appears to be worn unevenly, adjust
the wheel alignment.
3) Next, make a tire rotation between front and rear
as shown in the figure, make sure tires are worn
evenly.
4) Re-register the transmitter ID when rotation was
performed. TRANSMITTER ID, OPERATION, Subaru Select
