What Causes the Friction Noise from Car Door Seals?
3 Answers
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.
I recently encountered the issue of squeaking door seals caused by weather changes. The aged seals became stiff, rubbing against the car body when opening and closing the doors, producing a harsh noise. I tried cleaning them with a damp cloth to remove dust and dirt, but the effect was limited. Later, applying some silicone-based lubricant instantly made them much quieter. This reminded me that door seals require regular maintenance, such as checking them during seasonal transitions every summer to prevent dust buildup. Ignoring them not only causes annoyance but may also lead to poor door sealing, allowing rainwater to seep in, damaging the interior or causing rust. I recommend car owners pay attention to this detail—early intervention can save major trouble.
As a long-time professional working in an auto shop, I frequently assist customers in resolving such squeaking issues. The primary causes of door seal friction noise are aging and drying out or contamination with dirt, causing the seals to lose elasticity and scrape against each other during opening and closing. During inspection, first clean the seal surface using warm water and a soft-bristle brush to remove stubborn stains; then apply lubricant evenly—avoid using household oils to prevent corrosion. If the noise persists, it may indicate deformed seals or improper door closure, requiring gap measurement or replacement of new parts. I recommend maintenance every six months to extend seal lifespan and minimize repeated repair hassles.
