How to Solve Resonance Inside the Car?
2 Answers
Solutions for resonance inside the car include: 1. Replace the engine mounts to reduce resonance; 2. Adjust the connection points of the chassis crossmember to minimize resonance; 3. Perform overall engine maintenance to reduce resonance caused by operating conditions; 4. Apply sound insulation and vibration reduction measures to the engine front axle to reduce resonance. The causes of resonance inside the car are: 1. Loose rubber seals around the windows; 2. High-temperature fatigue and aging of the rubber in the engine mounts; 3. Engine misfire; 4. Deformation or improper installation of the engine guard plate; 5. Malfunction of the idle speed control system; 6. Debris in the window glass guide rails; 7. Loose internal parts of the dashboard.
I used to always feel that my car made a buzzing noise when driving fast, which was particularly annoying. Interior resonance is usually caused by imbalances, such as misaligned wheels or loose suspension. I need to try slowly, first checking if the tire pressure is consistent, inspecting each wheel for any imbalance, and getting a wheel balance at the repair shop for just a few dozen bucks. Then, I'll pop the hood and check if the engine mount screws are loose; if there's any wobble when I shake them by hand, I'll tighten them right away. I make sure not to leave things scattered inside the car, as too many loose items in the trunk can cause shaking and resonance, so I often keep it tidy. Also, if the exhaust pipe is old and cracked, it can buzz, so I’d need to replace the part. This issue isn’t a big deal; I can handle most of it myself with preventive measures, and regular maintenance is key. If the noise gets too loud, it might affect driving focus, so I shouldn’t delay fixing it for too long.
