What are the causes of wiper noise?

[StevenLee]

The causes of wiper noise are: 1. Aging of the wiper blade; 2. Foreign objects trapped between the wiper and the windshield; 3. Friction noise from the wiper linkage bushing; 4. Noise from the wiper motor. The wiper is a blade-like structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its main function is to clear rain, snow, and dust from the windshield that obstructs vision. Maintenance methods for wipers include: 1. When using the wiper to remove dust from the windshield on sunny days, always spray glass cleaner and avoid dry wiping; 2. If there are stubborn or hard contaminants on the glass, do not forcibly remove them with the wiper; 3. When washing the car or performing daily cleaning, lift the wiper before gently placing it back—do not let it snap back suddenly; 4. In winter, clear any ice particles from the windshield surface before using the wiper.

After driving for so many years, squeaky windshield wipers are a common issue. The main reason is that the rubber blades of the wipers have aged or severely worn out. Over time, they harden and crack, causing squeaking noises when rubbing against the glass. Additionally, if the windshield is contaminated with oil, dirt like bird droppings, or dust, the wipers won’t glide smoothly and will produce noise. During dry weather before rain, the rubber blades dry out and harden, making them even more prone to squeaking. I’ve encountered this several times myself. When inspecting, I first clean the windshield—using dish soap and water to wipe it thoroughly. If the noise persists, I check if the wiper arm is loose; loose screws can also cause clunking sounds. If all else fails, I replace the wiper blades. Don’t forget about the spring in the wiper arm bracket—insufficient tension can lead to uneven pressure and vibration noises. I recommend regular maintenance and replacing the wiper blades before the rainy season to avoid major issues. Once, I didn’t replace them in time, and the wipers chattered loudly on the highway, blurring my vision—it was extremely dangerous.

Dude, my car's wipers make this annoying squeaking sound every time I turn them on. Most likely, the rubber blades have worn out and hardened, making them scrape against the glass uncomfortably, especially after prolonged exposure to sunlight, which dries and cracks them, causing friction noise. Dirty glass is another common issue, like oil film or minor scratches—try washing it with dish soap and water. Improper installation can also be a problem; last time I replaced the wipers, they weren't aligned properly and clicked loudly for ages. Insufficient lubrication in the linkage mechanism can cause creaking sounds, so adding some lubricant might help. Remember, in winter frost, the rubber blades harden even more, making the noise worse—try turning on the wipers to warm them up for a few minutes before driving. Last time I chatted with my friend about cars, he mentioned how quiet his new car's wipers were because the blades were fresh. Checking it yourself is pretty simple: clean the glass to see if the noise stops, then manually wiggle the wiper arm to see if it moves smoothly.

I always check for minor issues when driving daily. The squeaking noise from windshield wipers is often caused by aged or hardened rubber blades or dirty glass, which increases friction. If the wiper arm linkage is loose or the spring tension of the bracket is uneven, it can vibrate and produce noise. I clean the glass with a damp cloth to remove grease and dirt as a simple solution; I replace the wiper blades every six months to prevent sticking; I also make sure no foreign objects like small stones are left on the car. These problems are easily overlooked but pose significant safety risks, especially in rainy weather when visibility can be blurred. It's advisable to maintain them regularly and develop good habits—this doesn't cost much but can save a lot of trouble.
