DISASSEMBLY SERVICE POINTS

<<A>> STRUT NUT REMOVAL

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

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

  • 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, 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.
Counterhold the piston rod, then use the wrench (special tool: MB991681) to remove the strut nut.

<<B>> STRUT DISPOSAL
caution Wear the protective glasses. Although the gas is harmless, drilling chips may be blown out by the gas.

The gas must be discharged from the strut before discarding it. Place the strut horizontally with its piston rod extended. Then drill a hole of approximately 3 mm in diameter at the location shown in the illustration and discharge the gas.

ASSEMBLY SERVICE POINT

>>A<< STRUT 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 the following special tool:

  • Spring compressor (MB991793)
  • Attachment A (MB991795)
  • Upper plate (MB991794)
  • Fixture (MB991830)

3.
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.
Counterhold the piston rod, then use the wrench (special tool: MB991681) to tighten the strut nut to the specified torque.
Tightening torque : 44 ± 5 N·m
