FRONT SUSPENSION

33-15

CAUTION

Be careful that the hand is not pinched by the coil spring 
when aligning the piston rod with the hole of upper insula-
tor while compressing the coil spring.
3. While passing the strut piston rod through the hole of upper 

insulator by hand, slowly compress the coil spring by the 
following special tool:

• Spring compressor (MB991793)

• Attachment A (MB991795)

• Upper plate (MB991794)

• Fixture (MB991830)

CAUTION

The locking nut for the piston rod inside the strut may be 
loose. Do not use the impact wrench to loosen the strut 
nut (jam nut).

4. Use the following special tools to tighten the strut nut (jam 

nut) to the specified torque:

• Wrench (MB991681)

• Socket (MB991682)

Tightening torque: 60 

± 9 N⋅m (45 ± 6 ft-lb)

INSPECTION

M1332001400315

• Check the bearing for wear or rust.

• Check the rubber parts for damage or deterioration.

• Check the spring for deformation, deterioration or damage.

• Check the shock absorber for deformation.

CAUTION

• The part indicated by 

*1

 indicates parts which should be temporarily tightened, and then fully tight-

ened with the vehicle standing on the ground and the curb weight condition.

• The parts indicated by 

*2

 are the bolts/nuts with friction coefficient stabilizer. In removal, ensure 

there is no damage, clean dust and soiling from the bearing and thread surfaces, and tighten them 
to the specified torque.

Post-installation operation
• Using your fingers, press the dust cover to check for a 

crack or damage.

• Wheel alignment check and adjustment (Refer to 

P.33-8

).

• Headlight aiming adjustment (Refer to GROUP 54A −

REMOVAL SERVICE POINT

.

<<A>> LOWER ARM ASSEMBLY REMOVAL

Rotate upward the stabilizer bar so as not to interfere the lower 
arm removal.

LOWER ARM CHECK

M1332001700930

• Check the bushing for wear and deterioration.

• Check the lower arm for bend or breakage.

• Check all bolts for condition and straightness.

.

LOWER ARM BALL JOINT ROTATION STARTING 
TORQUE

1. Move the lower arm ball joint stud back and forth for several 

times, and measure the lower arm ball joint rotation starting 
torque using the special tool preload socket (MB991006).

Standard value: 2.2 

− 4.1 N⋅m (19 − 36 in-lb)

2. If the measured value exceeds the standard range, replace 

the lower arm assembly.

3. Even if the measured value is within the standard range, 

check the lower arm ball joint that there is no looseness or 
gritty feeling. If there is no looseness or gritty feeling, it is 
judged as usable.

.

LOWER ARM BALL JOINT DUST COVER CHECK

1. Using your fingers, press the dust cover to check for a crack 

or damage.

2. If the dust cover has any crack or damage, replace the lower 

arm assembly (Refer to 

P.33-16

).

NOTE: If the dust cover has a crack or damage, the ball joint 
could be damaged.
If the dust cover is damaged during the maintenance, 
replace it.
