Disassembling Spring Strut

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.

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.

To prevent damage (deformation), clamp the spring strut in a suitable clamping block (tensioning device for MacPherson spring struts). Alternatively, the spring clamp can also be held in a retaining device.
Tension the coil spring using a spring clamp for spring struts Nr.121 until the piston rod is relieved. The appropriate forks must be inserted into the spring clamp.

Remove spring strut mount. To do this, loosen the lock nut on the piston rod (with coil spring pretensioned).
Use a socket-wrench insert 9630/2 to loosen the lock nut on conventional spring strut mounts. On PASM spring struts, use a suitable socket-wrench insert, e.g. socket-wrench insert for ATF temp. switch assembly Nr.18 .

When loosening the nut, counter at the piston rod (hexagon socket) or at the two grooves (cut-outs) on the stop plate (for PASM spring struts). Tools required: retaining tool 9630/1 and for conventional spring struts: counter-hold tool 9630 .
