What Are the Reasons for Loud Wiper Noise?
2 Answers
Wiper noise can be caused by: 1. Loose U-joint connections in the wiper frame or worn-out rubber blades; 2. Misaligned wiper arm angle, causing the blade to exceed a 0-degree contact with the windshield; 3. A rough or sticky windshield surface. The steps to remove wipers are: 1. Lift the wiper arm away from the windshield; 2. Keep the wiper perpendicular to the windshield for stability; 3. Locate the tab where the rubber blade meets the metal arm; 4. Press the tab to remove the old wiper. To operate the wipers: 1. Locate the wiper control lever on the left side below the steering wheel; 2. Push the lever up one position to activate the wipers; 3. To turn them off, push the lever down to the 'OFF' position.
Previously, while driving, the wiper noise was particularly loud, which really annoyed me. Upon closer consideration, it was most likely due to the wiper blades aging—hardened or cracked rubber causing squeaky sounds when wiping the glass. The windshield often had insect remains and oily film dirt, and after wiping it down, the noise reduced a bit. Improper installation is also a common cause, such as misaligned or crooked wiper blades, resulting in a jumping motion when wiping. A loose wiper arm spring can cause uneven pressure, preventing the blade from adhering tightly to the glass. I also noticed that on windy days or when driving at high speeds, airflow exacerbates the noise. Remember to perform regular maintenance, replacing the wiper blades once a year to avoid dry wiping. Use soapy water when cleaning the glass to keep it clean. These habits save hassle and ensure safety, requiring only a small investment to get things right.
