WARNING: Preloaded or pressurized components

Risk of squashing or bruising

→ Do not reach into the danger area.

→ Relieve the tension on components before starting work.

→ Secure components to prevent them from loosening suddenly.

Information

Protect electric lines when removing and installing the spring strut.
Do not lift/transport the spring strut/vibration damper at the electric lines.

To prevent damage (deformation), clamp the spring strut in a suitable clamping block (tensioning device for McPherson spring struts). Alternatively, the spring clamp can also be held in a retaining device.
Pre-tension the coil spring using spring clamp for spring struts Nr.121 until the piston rod is relieved. The appropriate forks must be inserted into the spring clamp.
Use socket-wrench insert 3186 or socket-wrench insert 9630/2 to loosen the hexagon nut (securing piston rod to spring-strut mount).
When loosening the hexagon nut, counter at the piston rod using a suitable open-ended wrench or ring wrench.
Remove all parts from the piston rod.
If the vibration damper is to be replaced on vehicles with PDCC, remove PDCC holder.
