Disassembling Front Spring Strut

WARNING: This page is about a different car, the 2024 Porsche Macan, 2023 Porsche Macan, 2022 Porsche Macan, 2021 Porsche Macan, and 2020 Porsche Macan. 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
→ Do not reach into the danger area.

→ Relieve tension on components before starting work.

→ Secure components to prevent them from loosening suddenly.

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.

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