Where Does the Wind Leakage Noise at High-Speed Window Corners Come From?
2 Answers
Roll down the window glass and press down on the upper right corner of the sealing strip near the door frame, and a small hole will appear. The wind enters from here, causing the wind leakage noise at high-speed window corners. You can roll 3M double-sided tape into a xylitol-sized shape and stuff it in until it's full, which can reduce the wind noise. Additionally, if you notice excessive noise inside the car during high-speed driving, you can check the following possible causes: Engine Noise: Engine abnormal noise is the most noticeable among car noises. Engine abnormal noises are divided into cold engine noise and hot engine noise. Cold engine noise refers to the abnormal noise coming from the engine compartment when starting the car, which disappears after the engine warms up. This noise occurs because the car has been parked for a long time, and the lubricating oil has almost entirely flowed back into the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure, and oil films cannot form between components, especially the valves inside the cylinder head (upper part). During a cold start, whether it's hydraulic lifters or mechanical rocker arms, there will be some valve clearance, or the timing chain may not operate properly due to insufficient oil pressure, leading to the noise. As for hot engine noise, excluding inherent factors, the noise either indicates a problem with a part or a malfunction of a certain component. Therefore, if you notice the engine noise is getting louder, you should promptly take the car to a repair shop for inspection. Tire Noise: Tire noise is generally caused by air flow through the gaps in the tire tread pattern, resulting in air noise. Since tires are made of rubber, they tend to harden and age over time, leading to natural noise production. New tires have good elasticity, offering better performance in terms of both noise and comfort. If the tire noise is too loud, check if the tires have aged, and replace them if necessary. Chassis Noise: Generally, chassis noise is due to problems with the shock absorbers. The entire car will produce significant noise when driving over uneven road surfaces. At this point, you should check the car's shock absorbers to see if there is severe oil leakage.
With over a decade of driving experience, I've found that wind noise at high speeds from window corners is usually caused by aging or deformed door seals. When rubber materials deteriorate over time or aren't properly installed, wind forces its way through gaps at high speeds, creating sharp whistling sounds at the corners. Having replaced seals several times, I've noticed that if windows aren't perfectly aligned or improperly installed, wind leakage becomes worse. I recommend regularly inspecting door edge seals for cracks or looseness, replacing them promptly when necessary. Applying rubber protectant during routine maintenance can slow down aging. Remember, ignoring minor issues will amplify the noise and may even compromise waterproofing during rainy conditions.
