REMOVAL
1. Install special tool MB991795 to special tool MB991793 as
shown in the illustration.
2. Set the strut assembly to the following special tools.
• MB991793: Spring Compressor
• MB991794: Upper Plate
• MB991795: Attachment A
• MB991830: Fixture
NOTE: Set the strut assembly by using the bolt and nut that
are removed from the vehicle. When installing the bolt and
nut, lightly tighten them by hand.
3. Compress the coil spring approximately 5 mm (0.20 inch)
using the spring compressor.
CAUTION
Do not use an impact wrench to tighten the strut nut, oth-
erwise the strut nut will be damaged. Vibration of the
impact wrench will cause the valve inside the strut to drop
out.
4. Use a hexagon wrench and a pipe to secure the strut, and
then remove the strut nut (self-locking nut) using special tool
MB991681.

WARNING
When the strut piston rod is positioned to the hole of
strut insulator with compressing the coil spring, be
careful not that your hand is jammed by the coil
spring.
2. Compress the coil spring slowly using the following special
tools, penetrating the strut piston rod to the hole of strut
insulator.
• MB991793: Spring Compressor
• MB991794: Upper Plate
• MB991795: Attachment A
• MB991830: Fixture
3. While the coil spring is being compressed by the special
tools, temporarily tighten the strut nut (self-locking nut).
4. Ensure that the arrows on the strut bracket center and the
strut insulator are positioned as shown.
CAUTION
Do not use an impact wrench to tighten the strut nut, oth-
erwise the strut nut will be damaged. Vibration of the
impact wrench will cause the valve inside the strut to drop
out.
5. For 3.8L engine models, using special tool MB991681, a
hexagon wrench and a pipe, tighten the strut nut
(self-locking nut) to 65
± 5 N⋅m (48 ± 4 ft-lb).
