What causes the noise during shock absorption in a Mercedes-Benz E300L?

Noise during shock absorption in a Mercedes-Benz E300L is caused by abnormal shock absorbers. Procedure for checking shock absorbers when noise occurs: Most noise from the shock absorbers in a Mercedes-Benz E300L is due to oil leakage. To check for oil leakage, inspect the shock absorber housing or dust cover when it hasn't rained or the car hasn't been washed. Alternatively, press down on the upper part of each wheel's suspension, such as the front and rear fenders. A faulty shock absorber will feel unusually stiff when pressed, which is a symptom of advanced oil leakage. Faulty shock absorbers can only be replaced and cannot be repaired. Causes of noise during shock absorption: Noise during shock absorption in a Mercedes-Benz E300L may be caused by loose or deformed chassis components, tire noise, front or rear wheel bearings, or various issues from installation, replacement, or maintenance, such as improperly tightened screws, component interference, incorrect positioning, or reverse installation.
I drive a Mercedes-Benz E300L, and last time there was a creaking noise from the suspension. I researched it for quite a while. This issue is quite common—most of the time, it's due to shock absorber leakage causing insufficient damping, or internal component wear that creates noise on bumpy roads. It could also be caused by loose suspension springs or aged/deformed rubber bushings, which creak when lacking lubrication. If the noise only occurs during turns or at low speeds, it's even more suspicious, like loose or rusted connecting parts. Checking it myself is simple: first, park and listen for the noise location. If there are oil stains on the shock absorber or deformed springs, they need replacement. Mercedes-Benz cars are precisely engineered, so don’t delay fixing this issue—it could affect handling safety. Later, I went to the dealership, and they diagnosed it as aged shock absorbers. After replacement, the noise was gone. To extend their lifespan, avoid rough road conditions while driving. Don’t wait until the noise worsens to repair it—that could cost more or even damage the chassis.
It's really annoying when the car's suspension makes strange noises. Based on my experience, the first thing to consider is daily driving habits. For the Mercedes-Benz E300L, suspension issues are mostly caused by wear and tear on components, such as broken shock absorber seals, insufficient spring support, or loose connecting screws. If the noise is particularly noticeable during low-speed acceleration, it might be due to aging bushings causing increased gaps. I've encountered situations where prolonged driving led to dust and rainwater corroding parts, resulting in friction noises. You can perform a simple check yourself: squat next to the tire to see if the shock absorber is leaking oil or rusting, and shake the car body to listen for the source of the noise. Don't ignore this—long-term neglect can accelerate wear on other components and increase fuel consumption. It's recommended to check tire pressure and clean the undercarriage monthly as a preventive measure. If you hear any unusual noises, take the car to a professional shop for instrument diagnostics. Mercedes-Benz parts are expensive, but timely repairs can save you a lot of money in the long run. Safety comes first, after all.
