What Causes the Friction Noise from Car Door Seals?

[DelHolden]

The causes of friction noise from car door seals are: 1. Excessive door gap size; 2. Improper door height (too high or too low); 3. Loose door tension; 4. Aging of door sealing strips. Precautions for door usage: 1. When opening/closing doors, check if limiters are abnormal - avoid violent operation; 2. Don't slam doors too hard as this affects sealing performance and may cause subtle deformation over time; 3. Avoid touching sealing strips during operation to prevent damage, especially in winter - never force open frozen doors, let them thaw naturally. The main door structure consists of outer panel, inner panel, interior/exterior trim and accessories, mounted via hinges to door pillars, primarily ensuring passenger safety during driving.
