What Causes Loud Noise When Closing Car Doors?

[BradleyDella]

Here are the specific reasons for loud noise when closing car doors: 1. Worn door hinges: Wipe off surface dust with a cloth or tissue, then use a cotton swab dipped in a small amount of lubricating oil to repeatedly apply to the hinge and circled areas of the door limiter. Open and close the door repeatedly, and repeat the steps of applying oil and operating the door until the noise disappears. Avoid applying excessive lubricant to prevent contamination of other door parts. If the issue persists, it may be due to wear and require replacement of new hinges and limiters. 2. Aging door seals: Check if the door seals are aging. As seals are rubber products, regularly clean dust and rainwater from seal gaps to prevent aging. Since seal gaps easily accumulate sand and dust, frequently clean them with a brush and apply a layer of high-permeability protective agent to prevent seal aging. If the seals are severely damaged or significantly aged, replacement with new seals is necessary.
