Disassembling Spring Strut

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. 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.
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 a socket-wrench insert 9630/2 to loosen the lock nut (securing piston rod to spring strut mount).
When loosening the nut, counter it at the piston rod (for conventional spring struts) or at the two grooves (cutouts) of the stop plate (for PASM spring struts). Tools required: retaining tool 9630/1 and for conventional spring struts arm bracket 9630 .
