How to Deal with the Abnormal Noise of Mercedes-Benz E300L on Bumpy Roads?
2 Answers
Over time, gaps may develop in some parts of the car body, causing friction between certain components when driving on unpaved roads or during emergency braking, resulting in abnormal noises. Below are the solutions to address these noises: 1. Body Noise: For body noise, it is recommended to visit a 4S shop to check the tightness of the chassis screws and connecting parts, and to inspect whether any components of the body are rubbing against each other. 2. Window Noise: If there is noise from the windows, roll down the glass, clean the rubber sealing strips around the window frame, and use a damp cloth to wipe between the two rubber strips until the dust is removed, which should eliminate the noise.
I used to encounter quite a few cases of abnormal noises from Mercedes-Benz E300L on bumpy roads, mostly due to suspension system issues. Problems like aging shock absorbers with oil leakage, cracked rubber bushings, or loose control arms can cause creaking sounds on rough surfaces. First, try to identify whether the noise is coming from the front or rear wheels, then check if the tires are deflated or if the rims are deformed. A simple test is to shake each wheel to see if there's any looseness. From a safety perspective, this can affect handling and may lead to vehicle instability, so don't delay—head to a 4S shop or professional repair shop promptly. They'll use a lift to thoroughly inspect the chassis components for potential replacements. Remember to pay attention to suspension parts during regular maintenance; checking them every 20,000 to 30,000 kilometers can prevent major issues.
