What are the solutions for car door squeaking?

[Cameron]

Solutions for car door squeaking: 1. Lubricate the hinges: The door and body are connected by hinges, similar to a household door. It's normal for hinges to squeak over time. To ensure smooth and quiet operation, apply lubricant every 2-3 months for maintenance. 2. Clean the door limiter: Another component connecting the door and body is the door limiter. Open the door to its maximum angle, clean the grease and dirt from the limiter arm, pin shaft, and connecting bracket surfaces, then apply an appropriate amount of grease to the upper and lower surfaces of the arm. 3. Check for seal aging: If the car has been used for a while, inspect whether the door seals have aged. Since seals are made of rubber, they can deteriorate and crack over time, leading to noticeable wind noise and friction sounds. If the seals are aged or damaged, it's recommended to replace them directly. Additionally, regularly clean dust and rainwater from the seal gaps to prevent aging.
