REAR WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
M1341011000372
Measure wheel alignment with an alignment
equipment on level earth.
The rear suspension, wheels, and tyres should be
serviced to the normal condition prior to wheel
alignment measurement.
CAMBER
Standard value: -0° 40' ± 30' (Left/right
deviation within 30')
CAUTION
Never subject the wheel bearings to the vehicle
load when the rear wheel hub nuts (self-locking
nuts) or special tool wheel alignment gauge
attachment (MB991014) are loosened.
NOTE:
For vehicles with aluminium wheels, attach the
camber/caster/kingpin gauge to the trailing arm
spindle by using special tool wheel alignment gauge
attachment (MB991014). Tighten the special tool to
the same torque 175
± 25 N⋅m as the rear wheel hub
nut (self-locking nut). MB990947 Lower arm bushing arbor Trailing arm bushing

If camber is not within the standard value, adjust by
following procedures.
1. Disconnect the conjunction of the control link and
the trailing arm.
2. Carry out adjustment by turning the camber
adjusting bolt (lower arm assembly mounting bolt
which is located on the inner side of the body).
NOTE: .
•LH: Clockwise viewed from the front → (+)
camber
•RH: Clockwise viewed from the front → (-)
camber
•The scale has gradations of approximately 14'.
CAUTION
To prevent bushings from breakage, the
connecting bolt should be temporarily tightened,
and then fully tightened to 90 ± 10 N⋅m with the
vehicle on the earth in the unladen condition.
3. Tighten the control link to the trailing arm.
4. After adjusting the camber, the toe should be
adjusted.
TOE-IN
Standard value:
At the centre of tyre tread: 3 ± 2 mm
Toe angle (per wheel): 0°08' ± 05'If toe-in is not within the standard value, adjust by
following procedures.
CAUTION
To prevent bushings from breakage, the control
link mounting nut should be temporarily
tightened, and then fully tightened to 120 ± 10
N⋅m with the vehicle on the earth in the unladen
condition.
Carry out adjustment by turning the toe adjusting bolt
(control link mounting bolt which is located on the
inner side of the body).
NOTE: .
•LH: Clockwise viewed from the front → Toe-in
•RH: Clockwise viewed from the front → Toe-out
•Turning the toe adjusting bolt by one groove of
the scale, toe can be changed approximately 2.6
mm (single side toe angle equivalent to 16').
CONTROL LINK PILLOW BALL BUSHING
AXIAL PLAY CHECK
M1341018500011
1. Raise the vehicle.
2. Move the control link up and down with your
hands to check for an excessive play in the axial
direction of the pillow ball bushing. If there is an

AXIAL PLAY CHECK
M1341016900057
1. Raise the vehicle.
2. Remove the stabilizer link and shock absorber
from the lower arm assembly.3. Move the lower arm up and down with your hands
to check for an excessive play in the axial
direction of the pillow ball bushing. If there is an
excessive play, replace the lower arm pillow ball
bushing (Refer to P.34-10).
4. After inspection, install the stabilizer link and
shock absorber to the lower arm assembly (Refer
to P.34-8).

COVER INSPECTION
M1341012800274
1. Check stabilizer link ball joint dust covers for
cracks or damage by pushing it with your finger.
2. If a dust cover is cracked or damaged, replace the
