What Causes the Squeaking Sound from Car Doors While Driving?

[VanAiden]

Squeaking sounds from car doors while driving are typically caused by aging door seals. Below is relevant information about car doors: 1. Design Requirements: Ensure convenient passenger access with maximum opening angle controlled at approximately 65°-70°. Doors should not interfere with other components during operation, must lock securely when closed, and must not open automatically while driving. 2. Definition: Car doors provide entry/exit passages for drivers and passengers while isolating external disturbances. They offer some protection against side impacts and contribute to vehicle aesthetics through their design. Door quality is primarily reflected in: impact protection performance, sealing performance, and opening/closing convenience, along with other functional indicators. Impact protection is particularly crucial as side collisions offer minimal buffer distance, making passengers vulnerable to injury.
