The solutions for a squeaky car door are: 1. Check for any foreign objects inside the door trim panel and remove them promptly if found; 2. Inspect whether the trim panel or audio system is loose; 3. Examine if the door hinges are rusted; 4. Replace the door seal strip; 5. Check if the door lock mechanism has poor contact, excessive gap, or insufficient lubrication. The causes of a squeaky car door are: 1. Presence of foreign objects inside the door trim panel; 2. Loose trim panel or audio system; 3. Rusted door hinges; 4. Aged door seal strip; 5. Poor contact, excessive gap, or insufficient lubrication in the door lock mechanism.

I've been driving for over a decade and have encountered squeaky car doors several times. It's usually due to accumulated dust or rust in the hinges, or dried-up lubricant. First, use a clean cloth to wipe the hinges and door frame, making sure no sand particles remain. Then, spray some dedicated door hinge lubricant, like WD-40 in a spray can, which you can easily find at supermarkets. After spraying, gently open and close the door a few times to let the oil penetrate. If the squeaking persists, check if the door seal is aged or cracked, which is common in older cars. I recommend simply wiping the hinges monthly with a damp cloth as a preventive measure. Avoid using engine oil or similar oils as they attract dust and make things worse. If the door noise becomes severe, get it fixed immediately to prevent issues like difficulty opening/closing or water leakage during rain.

My old car used to have this annoying squeaking problem that gave me a headache. I tried using leftover soapy water at home, applying a bit on the hinges, and it actually worked for a while. Later, I realized it was due to excessive dust buildup, so I cleaned it with a small brush and then lubricated with some vegetable oil—cheap and simple. Remember not to spray too much, as the oil can drip and stick to the car, making cleanup troublesome. I suggest trying DIY solutions first. If the issue persists, it might indicate loose internal door components or damaged seals. After buying a new car, I made it a habit to perform quarterly maintenance, including cleaning door hinges, and now the noise is much less frequent. If you park under trees often, dust accumulates quickly—early detection and treatment are key.

In my generation, when car doors squeaked, it was often due to rusty door hinges. We would apply some grease for lubrication, which worked quite well. The same principle applies today: first, use a cloth to clean off the rust, then spray some anti-rust lubricant. Remember to check if the door lock is deformed, as it can loosen over time. Young car owners shouldn't ignore this; if left unfixed, the door may become difficult to open or close, or even damage the hinges. Simple maintenance can extend its lifespan.
