Disassembling Rear Spring Strut (Steel Springs)

WARNING: This page is about a different car, the 2014 Porsche Cayenne, 2013 Porsche Cayenne, 2012 Porsche Cayenne, and 2011 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Preloaded or pressurised components

Risk of squashing or bruising
1. Do not reach into the danger area.
2. Relieve tension on components before starting work.
3. Secure components to prevent them from loosening suddenly.

The next sections describe the spring struts with and without PASM.

Vehicles with PASM: Push both grommets -1- and -2- on the connector cable to one side.

Grommets
Vehicles with PASM: Mark the position of the cables in the connector so that they can be inserted at the same position again during re-installation. Loosen the lock in the connector and unpin both cables from the connector.
Vehicles with PASM: Remove grommets -1- and cable guide -2- by opening the grommets slightly using a commercially available Seeger circlip ring pliers. This makes it easier to pull the pins through the grommets.
