Why does the wiper suddenly make a creaking noise when wiping the windshield?

Wiper suddenly making a creaking noise when wiping the windshield is due to improper installation of the wiper blade support frame. Wiper blades are rubber products that will harden and age after prolonged use, especially in winter. If the wiper is no longer cleaning effectively, the simplest and most effective solution is to directly replace the wiper blades. It is recommended to replace them every one to two years. The technical name for wipers is "windshield wipers," which are blade structures installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade. Their main function is to clear rain, snow, and dust from the windshield that obstruct the driver's view, improving visibility and enhancing driving safety.
Speaking of this, I've noticed that squeaky windshield wipers are mostly caused by worn-out wiper blades. The rubber material hardens or deforms after prolonged exposure to weather, leading to that annoying squeaking sound when in use. I've checked similar cases before, and it often happens after a car has been driven for a year or two. If there's oil film or debris like insect remains on the windshield, it can also cause noise. Worse, dry wiping increases friction, making the wiper blades bounce and produce that squeaky sound. The solution is simple: first, try thoroughly cleaning the windshield with some glass cleaner; if that doesn’t work, just replace the wiper blades. Don’t wait until they completely fail—otherwise, when the rainy season comes, poor visibility could lead to accidents. I recommend checking them every six months. Wiper blades are cheap; just buy a reputable brand online, and replacing them takes only five minutes. By the way, spraying windshield washer fluid can temporarily reduce the noise, but it’s not a long-term fix.
