Disassembling Front Spring Strut (Steel Springs)

Information 

Recommendation for workshops replacing shock absorbers/spring dampers:

• Dampers can be replaced separately up to a mileage of 30, 000 km or 3 years. 
• If the mileage is > 30, 000 km or the components are more than 3 years old, we recommend replacing them in pairs. 

Information 

• The pictures shown in this document may differ from the original. 
• However, this does not affect the validity and relevance of the pictures. 

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

1. On vehicles with PASM, push both grommets on the connector cable (PASM) to one side.
2. On vehicles with PASM, mark the position of the cables so that they can be fitted at the same position again during re-installation.

   Loosen the locking mechanism in the connector and unpin both cables from the connector.

3. On vehicles with PASM, remove the grommets by opening the grommets slightly using a commercially available Seeger circlip ring pliers. This makes it easier to pull the pins through the grommets.
4. To make assembly easier, mark the spring strut according to concave support, steel spring and shock absorber. > Marking spring strut
