Disassembling Rear Spring Strut (Steel Springs)
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.
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.
- 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 locking mechanism 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 commercially available Seeger circlip pliers. This makes it easier to pull pins through the grommets.
- Loosen the four fastening nuts -1- on the cover uniformly and remove the cover.
- Pre-tension coil springs using a spring compressor Nr.121-1 Pos.1
and tensioning plate Nr.121-1 Pos.6
until the piston rod is relieved.
WARNING: Danger of injury due to spring tensioning.
- Never use an impact bolter to loosen or tighten the lock nut.
- Use a commercially available change-over ratchet.
- Carefully remove the lock nut on the piston rod at the supporting mount using socket-wrench insert 3353 or for PASM, socket-wrench insert 3077 .
- Remove all parts from the piston rod.
