Problem overview

Some Mercedes-Benz SL55 AMG owners report experiencing issues related to a worn-out left front strut after replacement, which may be attributed to several common suspension problems. These include significant force on control arm bushings during braking, cornering, and acceleration, leading to premature wear. Additionally, some owners have encountered valve block issues, where worn O-rings cause hydraulic fluid leakage, resulting in the suspension dropping when parked, particularly in models equipped with ABC suspension. A faulty ADS level control valve at one of the air struts can also lead to a stiff and stuck suspension, especially noticeable in SPORT mode. Furthermore, general wear and tear on suspension components like shocks, struts, and bushings can lead to a bumpy ride, reduced handling, and uneven tire wear. It is crucial for owners to thoroughly inspect the suspension system to identify these potential issues and ensure proper maintenance and repair.
