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 lock nut for the piston rod inside the strut may be loose. Do not use the impact wrench to loosen the strut nut.

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

[[B]] STRUT DISPOSAL

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





Install the coil spring to align the bottom with the shape of the strut spring seat.

]]B[[ UPPER SPRING SEAT INSTALLATION





Align the D-shaped hole with the D (cut-off) of the strut, and install the marked part shown in the figure facing the inside of the vehicle.

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

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





2.
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 special tool: MB991793, MB991795, MB991794 and MB991830.





CAUTION:
The lock nut for the piston rod inside the strut may be loose. Do not use the impact wrench to tighten the strut nut (jam nut).

3. Use special tools MB991681 and MB991682 to tighten the strut nut (jam nut) to the specified torque:
GREASE: Shell Retinax Grease CL0
Tightening torque : 61± 9Nm (45± 6 ft-lb)
