How to Deal with Resonance Inside the Car?
2 Answers
Resonance inside the car should be handled as follows: 1. Take the car to a 4S shop as soon as possible for a comprehensive inspection and adjustment. Engine resonance involves comprehensive issues such as components, joint processing, and tuning. It is recommended to have the problematic vehicle inspected and repaired as soon as possible; 2. Replace the engine mounts to try to reduce resonance; 3. Adjust the connection points of the chassis crossmember to reduce resonance; 4. Perform overall maintenance on the engine to reduce resonance caused by working conditions; 5. Apply sound insulation and vibration reduction treatment to the engine front axle to reduce resonance. Here is an introduction to resonance: Resonance is a physical phenomenon, which is the frequency at which an object tends to vibrate. Taking clocks, guitar strings, and tuning forks as examples, they all tend to vibrate at specific frequencies when excited by external forces. The suspension system, and even the engine within the mounts, have a tendency to vibrate at certain frequencies.
I have dealt with car resonance issues and found that the most common cause is loose objects inside the vehicle, such as tools in the trunk or debris under the seats, which vibrate and produce a buzzing sound while driving. First, take some time to clean up and secure all items. Then, check if the tire pressure is consistent, as unbalanced or unevenly worn tires are more likely to cause resonance, especially at specific speeds. Loose exhaust pipe mounting bolts are also a major concern—try tightening them with a wrench. If the problem persists after your own inspection, it might be a more complex issue with the body structure, and it's advisable to visit a professional auto repair shop for dynamic balancing or a comprehensive inspection. Resonance not only affects driving comfort but can also lead to premature damage to other components. Having a mechanic tighten everything during regular maintenance can effectively prevent trouble.
