DISASSEMBLY SERVICE POINTS

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





1. Install special tool MB991795 to the special tool MB991793 as shown in the figure.





2. Set the strut assembly to special tools: MB991793, MB991795, MB991794 and 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 (0.20 in).





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 special tools MB991681, MB991682 to loosen the strut nut (jam nut):

[[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 strut 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





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.

3. While passing the strut piston rod through the hole of upper insulator by hand slowly compress the coil spring by special tool: MB991793, MB991795, MB991794 and 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 special tools MB991681 and MB991682 to tighten the strut nut (jam nut) to the specified torque:
Tightening torque: 60 ± 9 Nm (44 ± 6 ft-lb)
