What Causes the Loud Sound When Windshield Wipers Swing Back and Forth?
1 Answers
Windshield wipers produce loud noises for the following reasons: 1. Wiper blade issues: The noise is caused by problems with the wiper blade itself. Wiper blades are made of rubber and will harden or age over time, especially noticeable in winter. 2. Foreign objects: Noise occurs when there are foreign objects between the wiper blade and the windshield, causing sharp friction sounds when the wipers are activated. 3. Bushing friction: The sound comes from the friction of the wiper linkage bushing. Over time, the wiper linkage mechanism ages, reducing the elasticity of the wiper arm spring, and the bushing may wear out or even fall off.
