What Causes Loud Wiper Noise?
3 Answers
Wiper noise is caused by: Aging Parts: Looseness at the U-joint contact area of the wiper frame or wear and tear of the rubber blade. Angle Misalignment: Misalignment of the wiper arm angle, causing the wiper to exceed a 0-degree angle with the glass surface. Improper Maintenance: Always check if the upper and lower wipers swing in sync; correct any asynchrony promptly. If the wiper emits a heavy "squeaking" noise during operation, there may be an issue with the wiper's adjustment, possibly due to excessive downward pressure. If some moisture remains on the windshield after several wipes, it indicates that the rubber blade is aged and needs replacement. Never operate the wiper on a dry surface, as it not only damages the wiper itself but can also cause significant harm to the glass if there are particles or other foreign objects. Regularly lubricate the wiper. Frequently apply lubricant at the wiper arm joints to reduce mechanical friction.
The loud noise from my wipers is a common issue, especially after prolonged use, when they squeak incessantly. The main reasons are: first, the wiper blades have aged, and the hardened rubber causes loud noises when scraping against the glass; second, there might be oil film, dirt, or small stones on the windshield, causing severe friction when the wipers pass over them; third, the wiper arm might be loose or misaligned, leading to uneven contact and scraping. Last year, my car had this problem—bugs stuck to the windshield during summer highway driving, making a terrible noise when the wipers moved. I tried cleaning the glass myself first with glass cleaner, then replaced the blades, and the noise reduced immediately. Regular maintenance is crucial; checking the blade wear every six months is necessary. In cold weather, the rubber hardens and is more prone to noise, so it’s best to take preventive measures before the rainy season to avoid dangerous low visibility during rainy nights.
As a driver who often drives family members around, loud wiper noise can really affect my mood. I believe the main reason is blade aging—the rubber hardens over time, causing squeaky sounds when wiping. Another cause could be a dirty windshield, such as oil stains or tree sap sticking to it, which makes the wipers produce noise. Loose wiper arms are also a possibility; if not securely installed, they can rub against the glass and create noise. Don’t underestimate this loud noise issue—it might indicate poor wiping performance, obstructed vision during rain, and significant safety risks. I’ve encountered this a few times and solved it myself: first, thoroughly clean the windshield, and the noise often reduces after removing stains. If that doesn’t work, replace the blades immediately—a new set costs just a few dozen bucks. Parking away from trees to reduce leaves sticking to the glass can also prevent this issue. Regular maintenance extends the lifespan of the wiper system, ensuring safer and smoother driving.
