Mercedes shock absorber noise is generally a normal phenomenon and not a malfunction. Due to the structure of the shock absorbers in Mercedes E-Class vehicles, the entire shock absorber is compressed when the vehicle passes over bumpy roads, thereby compressing the external spring. After the vehicle traverses the bumpy section, the spring's elasticity causes the shock absorber to reset. During this compression and resetting process, a "hissing" or "whooshing" sound of air release may accompany the movement. However, if the shock absorber noise is anything other than this, it is an abnormal phenomenon, such as oil leakage from the shock absorber. Mercedes shock absorbers bear the weight of the vehicle itself and passengers daily, while also mitigating road bumps. Hundreds of thousands of compressions can affect their lifespan, leading to damage, with the most common issue being oil leakage. After oil leakage, the internal oil pressure of the entire sleeve decreases, reducing the shock absorption effect and causing abnormal noises due to the leakage. Such noises are mostly the "clanging" sound of hard objects hitting each other or the "squeaking" sound of friction. The method to determine this is relatively simple: observe the vehicle's shock absorbers when the Mercedes has not been washed, checking for the presence of oil sludge or stains. If present, it can be concluded that the shock absorber is leaking oil. Minor seepage may not require much attention, but if the leakage is severe, timely replacement is necessary to reduce safety hazards. Moreover, faulty shock absorbers can only be replaced and cannot be repaired.
