DISASSEMBLY SERVICE POINTS
[[A]] SELF-LOCKING NUT REMOVAL
CAUTION: The locking nut for the piston rod inside the shock absorber may be loose. Do not use an impact wrench to loosen the self-locking nut.
1. Install the special tool MB991796 to the special tool MB991793 as shown in the figure.
2. Set the strut assembly to special tools: MB991793, MB991796, MB991794 and MB991830.
NOTE: Use the bolts and nuts removed from the vehicle to secure the shock absorber assembly and tighten them lightly by hand.
3. After setting the shock absorber assembly, operate the spring compressor and compress the coil spring by approximately 5 mm (0.20 in).
4. While holding the piston rod as shown in the figure, remove the self-locking nut.
[[B]] SHOCK ABSORBER DISPOSAL PROCEDURES
CAUTION: Wear the protective glasses. Although the gas is harmless, drilling chips may be blown out by the gas.
