How to Reduce Excessive Noise in the Fit?
3 Answers
To address excessive noise in the Fit, you can perform a full-car sound insulation treatment, which should reduce the decibel level by approximately 5. However, this option is not inexpensive, as it requires high-quality sound insulation materials, including wheel arch insulation and engine firewall insulation. Below are specific details about the Fit: 1. The Fit features a front MacPherson strut independent suspension and a rear torsion beam non-independent suspension structure. The difference lies in the front suspension's geometric design. The rear suspension has also undergone partial adjustments, including the shock absorber mounting angle and torque-decomposed shock absorber brackets. Additionally, both front and rear suspensions are equipped with stabilizer bars to enhance body stability during cornering. 2. The exterior has been fitted with a new body kit. If you're primarily looking for a compact car for commuting purposes, the Fit would be an ideal choice, making it a perfect option.
When I first drove the Fit, I also found the noise particularly bothersome, but later I figured out a few tricks. First, check the tires—the factory-fitted ones are durable but poor at noise reduction. After 20,000 kilometers, the tire noise was like thunder. I replaced all four with quiet tires, and the highway noise was immediately halved. The thin layer of sound insulation in the engine bay was practically useless, so I bought some soundproofing material and added it to the engine hood and wheel arches, costing just over 200 yuan. There was also the issue of aging door seals letting in wind, so I spent a few dozen yuan to replace the entire set of rubber seals. I also developed a habit of clearing leaves and debris from the roof gutter before driving. Now, even driving with the windows down on the expressway doesn’t feel noisy. The key is doing it yourself and solving big problems with small investments.
I specialize in car maintenance, and the noise issues with the Fit are usually due to multiple factors. Let me highlight three key points: First, use the correct engine oil—if the manual recommends 0W-20, don’t switch to a higher viscosity oil, as the engine sound will noticeably become smoother. Second, pay attention to the chassis components, especially loose underbody panels or worn exhaust hangers—the clunking noise over speed bumps often stems from here. Third, avoid piling up clutter in the trunk, as the thin metal in the spare tire well can easily resonate and amplify noise. Last time, a customer complained about excessive wind noise, which turned out to be aging windshield seals—applying a bead of sealant fixed it. These checks aren’t complicated, and a repair shop can diagnose them in half an hour.
