What causes loud and shaky wiper operation?
3 Answers
Reasons for loud and shaky wiper operation: 1. Wiper rubber strip aging - As a rubber component, the wiper blade hardens over time and loses proper contact with the windshield, causing vibration. Solution: replace the rubber strip. 2. Incorrect wiper-to-glass contact angle - This creates uneven pressure distribution during operation, leading to shaking. Solution: adjust the wiper's contact angle for even pressure distribution. Wipers (also called windscreen wipers or windshield wipers) are devices that remove rain and dust from vehicle windshields to improve driver visibility and enhance driving safety.
I'm familiar with this issue. Loud and shaky wiper blades can be quite annoying. The most common cause is aging wiper blades—the rubber strips harden and crack after a few years, leading to uneven wiping and causing noise and vibration. Another possibility is a dirty windshield with oil film, dust, or tree sap, which makes the wipers skip and jump during operation. Also, check if the wiper arm mounting points are rusted or loose, as this can create uneven pressure and worsen the shaking. Faulty wiper motors or linkage systems may also cause vibrations and unusual noises. My advice: first, thoroughly clean the windshield with glass cleaner to remove any oil film. If that doesn’t work, replace the wiper blades—it’s a cheap DIY fix, costing just a few bucks. If the problem persists, visit a repair shop to inspect the chassis components—don’t delay, as it could compromise visibility and safety in rainy conditions. Regular maintenance, like replacing wipers every six months, can prevent such issues.
Don't underestimate wiper issues like this. The noise not only affects driving comfort, but the shaking can also blur your vision during rain, increasing accident risks. Main causes include aged wiper blades losing wiping efficiency and creating friction noise, or dirty windshield surfaces (like insect remains) causing unstable movement. Another possibility is misaligned wiper arms or rusted transmission mechanisms worsening the vibration. My advice: Act quickly - first clean the windshield thoroughly with proper tools to see if noise improves; if not, replace the blades immediately. For severe shaking, check for bent linkage rods or insufficient lubrication - don't risk delaying repairs. Make it a habit to inspect wiper condition before rainy seasons to ensure proper operation. Safety always comes first.
