Disassembling Front Spring Strut

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 

If the coil spring is replaced: Always replace coil springs in pairs only!

1. Clamp the spring strut in >VAS 6908 - stationary spring tensioning device  in such a way that the mounting plates of the spring tensioning device are positioned on the spring strut supporting mount. >Front spring strut in spring tensioning device

   WARNING: Preloaded or pressurized components 

   • Risk of squashing or bruising

     → Do not reach into the danger area.

     → Relieve tension on components before starting work.

     → Secure components to prevent them from loosening suddenly.

2. Pre-tension the spring strut until the tension on the piston rod is relieved.
3. Loosen hex nut -1-  using a commercially available open socket-spanner insert (a/f 21 mm), for example Hazet, number 2593  .

   Counter at the hexagon nut -2-  on the piston rod.
