Disassembling Front Spring Strut

Information 

Recommendation for workshops replacing shock absorbers/spring dampers:

• Dampers can be replaced separately up to a mileage of 20, 000 mls (30, 000 km) or 3 years. 
• If the mileage is > 20, 000 miles (30, 000 km) or the components are more than 3 years old, we recommend replacing them in pairs. 

Information 

• Observe the correct allocation (engine variant/chassis variant) when installing new coil springs and/or shock absorbers. 
• Springs must only be replaced in pairs. 
• When replacing springs, the spring plates must also be replaced. 

Information 

The front spring strut is disassembled and assembled using the tool > VAS 6908 - Stationary Spring Compressor  .

Before inserting the spring strut, the tool > VAS 6908 - Stationary Spring Compressor  must be set up and adjusted in accordance with the operating instructions provided by the manufacturer.

1. Insert spring strut in > VAS 6908 - stationary spring tensioning device  > Spring strut in spring tensioning device (conventional spring strut shown)  .
