DISASSEMBLY SERVICE POINTS

[[A]] STRUT NUT (JAM NUT) REMOVAL





1. Install the special tool attachment A (MB991795) to the special tool spring compressor
(MB991793) as shown in the figure.





2. Set the strut assembly to the following special tools:

- Spring compressor (MB991793)

- Attachment A (MB991795)

- Upper plate (MB991794)

- Fixture (MB991830)

NOTE:
Use the bolts and nuts removed from the vehicle to secure the strut assembly and tighten them lightly by hand.

3. After setting the strut assembly, operate the spring compressor and compress the coil spring by approximately 5 mm.





4.
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).

Use the following tools to loosen the strut nut (jam nut):

- Wrench (MB991681)

- Socket (MB991682)

[[B]] STRUT REMOVAL

CAUTION:
Wear the protective glasses. Although the gas is harmless, drilling chips may be blown out by the gas.





Before disposal of the strut, place the strut on the level surface with the piston rod extended, and make a hole of approximately 3 mm in diameter at the point shown in the figure to discharge the gas.

ASSEMBLY SERVICE POINTS

]]A[[ COIL SPRING INSTALLATION





1. Fit the coil spring to the spring tube securely.
2. Install the coil spring equipping with the spring tube to align the bottom with the shape of the strut spring sheet.

]]B[[ STRUT BEARING INSTALLATION

CAUTION:
Install the bearing without any damage.

]]C[[ STRUT NUT (JAM NUT) INSTALLATION

1. Check that both of the coil spring ends align with the spring sheet groove correctly.





2. Align the strut spring sheet hole with the upper spring sheet hole.
NOTE:
Use the pipe to align the holes easily.





3.
CAUTION:
Be careful that the hand is not pinched by the coil spring when aligning the piston rod with the hole of upper insulator while compressing the coil spring.

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)





4.
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).

Use the following special tools to tighten the strut nut (jam nut) to the specified torque:

- Wrench (MB991681)

- Socket (MB991682)
Tightening torque: 60 ± 9 Nm (45 ± 6 ft-lb)
