What Causes the Squeaking Noise of Besturn B70's Wiper?
4 Answers
Reasons such as excessive pressure on the vertical wiper arm of the windshield and looseness in the spring wiper system. Specific reasons: Excessive pressure on the vertical wiper arm of the windshield, looseness in the spring wiper system, hardening, deterioration, wear, and natural aging of the wiper rubber strip, etc. Solutions: Remove both wiper blades and gently place the wiper arms on the windshield; observe whether the small metal segment at the front hook of the wiper arm is parallel and tightly adhered to the glass; find a suitable tool, preferably pliers, to directly adjust the wiper arm, aligning the small metal segment of the hook to tightly adhere to the glass; you can try replacing the traditional frame wiper with a frameless wiper; the owner can clean the debris under the wiper and sand the wiper with sandpaper.
My Bestune B70 has been in use for a long time, and the wiper noise is quite common. The problem usually lies in the aging or wear of the wiper blades. When the rubber hardens, it creates more friction against the windshield, producing a squeaking sound, especially in the summer heat which accelerates hardening. It could also be due to an unclean windshield surface, with accumulated oil film, insect remains, or tree sap—these contaminants add noise when rubbed. First, check the windshield and clean it thoroughly with a dedicated cleaner, then inspect the wiper blades for cracks or deformations. Replacing the blades yourself isn’t difficult, and the parts cost around a hundred yuan online. Excessive noise can obscure vision in the rain, posing a driving hazard. Remember to service them every six months or 10,000 kilometers to prevent minor issues from becoming major ones.
My Bestune B70 wipers are always noisy, possibly due to improper installation or lack of lubrication. Lift the wipers to check if the blades are loose or cracked, then spray some wiper fluid to alleviate dryness. Sometimes dust or bugs sticking to the windshield can cause screeching noises when the wipers move, which worsens in winter as the rubber hardens in the cold. A simple DIY fix: rinse the windshield with washer fluid and clean off debris. Replacing the wiper blades with new ones costs less than 100 yuan—just search for the model on Taobao and install them yourself. Eliminating the noise improves visibility and reduces driving distractions. In hot weather, rubber deteriorates easily, so don’t delay repairs for too long.
The abnormal noise of the Bestune B70 wipers is often caused by uneven spring pressure of the wiper arms or wear of connecting parts. The main reason is the aging and hardening of rubber blades; excessive oil film buildup on the windshield increases friction noise; unstable motor movement may also cause shaking. It is recommended to remove the wiper blades to check for cracks and clean the windshield to remove dirt. Add protective agent when the lubrication mechanism lacks oil. Persistent noise not only affects visibility in rainy weather but may also damage other components if severe, requiring timely attention.
