What Causes Loud Friction Noise from Newly Replaced Wiper Blades?
3 Answers
If there are issues with incomplete cleaning and unusual noises after replacing the wiper blades, it is likely due to a dirty windshield. Below is an introduction to wiper-related knowledge: 1. Function: Wipers, also known as windshield wipers, are devices used to remove raindrops and dust from the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. Core Component: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is usually integrated with the worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque, with its output shaft driving a four-bar linkage mechanism that converts continuous rotational motion into a left-right oscillating motion.
I recently replaced my wiper blades, but they started squeaking loudly as soon as I turned them on, which is really annoying. The main reason could be that the new rubber strips weren't installed properly—if they're misaligned or the pressure is uneven, it causes friction noise. Also, if there's oil film or residue left on the windshield, incomplete cleaning can make the rubber strips slide less smoothly. I recommend thoroughly cleaning the glass first, using a dedicated glass cleaner with alcohol to remove grease. The quality of the rubber strips themselves is also a factor—cheap ones with poor rubber material and insufficient elasticity are prone to squeaking. If they weren't aligned during installation, you can try manually adjusting the angle of the wiper arm. When driving in the rain, the noise can be distracting, so it's important to address it quickly for safety. Don’t forget to check if the rubber strips match your vehicle model—ill-fitting ones can worsen the friction issue.
Excessive noise from newly replaced wiper blades is often caused by poor adhesion between the rubber blade and the windshield. Residual dirt or wax on the glass surface requires initial cleaning with foam cleaner. Improper installation angle or twisted blades creating uneven pressure can also generate abnormal sounds. The solution is simple: manually reset the wiper arm position to ensure the blade lies flat against the glass. Low-quality rubber blades may be another culprit - choosing premium brands enhances durability. Additionally, cold weather stiffens rubber, increasing friction noise which typically improves after driving briefly. Persistent noise warrants checking for blade damage or premature aging requiring replacement. Regular windshield cleaning should be incorporated into maintenance routines as preventive care.
