NOTE: The toe will move out as the left
turnbuckle is turned toward the front of the vehicle
and the right turnbuckle is turned toward the rear
of the vehicle.
2. Install the clip and tighten the lock nut to the
specified torque.
Tightening torque: 40 ± 5 N⋅m
3. Confirm that the toe-in is at the standard value.
4. Use a turning radius gauge to check that the
steering angle is at the standard value.
STEERING ANGLE
Standard value:
TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the
vehicle has been involved in an accident or if an
accident is presumed, it is advisable to check the
toe-out angle on turns in addition to the wheel
alignment.
Conduct this test on the left turn as well as on the
right turn.
Standard value:
CAMBER, CASTER AND KINGPIN
INCLINATION
Standard value:NOTE: *: difference between right and left wheels
must be less than 30'
NOTE: Camber and caster are preset at the factory
and cannot be adjusted.
CAUTION
Never subject the wheel bearings to the vehicle
load when the driveshaft nuts are loosened.
NOTE:
For vehicles with aluminium wheels, attach the
camber/caster/kingpin gauge to the driveshaft by
using special tool wheel alignment gauge attachment
(MB991004). Tighten the special tool to the same
torque 245
± 29 N⋅m as the driveshaft nut.
LOWER ARM BALL JOINT AXIAL PLAY
CHECK
M1332011300074
1. Raise the vehicle.
2. Remove the stabilizer link from the lower arm.
3. Move the lower arm up and down with your hands
to check for an excessive play in the axial
direction of the ball joint. If there is an excessive
play, replace the lower arm assembly.
LOWER ARM BALL JOINT COVER
CHECK
M1332008600321
1. Press the lower arm ball joint cover with your
finger to check that there are no cracks or
damage in the lower arm ball joint cover.
2. If the lower arm ball joint cover is cracked or
damaged, replace the lower arm assembly.
NOTE: If the lower arm ball joint cover is cracked
or damaged, it is possible that there may also be
damage to the ball joint. Inner

CAUTION
•Install special tool arm set (MB991238) evenly,
and so that the maximum length will be
attained within the installation range.
•Do not use an impact wrench to tighten the
bolt of special tool spring compressor body
(MB991237), otherwise the special tool will
break.
1. Use following special tools to compress the coil
spring.
•MB991237: Spring Compressor Body
•MB991238: Arm Set
WARNING
Do not use an impact wrench to remove the
strut nut (self-locking nut). Vibration of the
impact wrench will cause special tools
(MB991237 and MB991238) to slip and cause
personal injury.
2. Use following special tools to secure the strut, and
then remove the strut nut (self-locking nut).

<<B>> STRUT DISPOSAL
WARNING
Wear goggles when drilling to protect your
eyes from flying metal debris.
The gas must be discharged from the strut before
discarding it. Place the strut horizontally with its
piston rod extended. Then drill a hole of
approximately 3 mm in diameter at the location
shown in the illustration and discharge the gas.
