What are the causes of car door noises?
2 Answers
Car door noises are caused by: 1. Poor door quality; 2. Abnormal noise from the door's internal cables; 3. Damaged door stopper; 4. Aging door seals; 5. Insufficient lubrication of door hinges. Solutions for car door noises include: 1. Removing foreign objects from the door frame; 2. Tightening the interior panels; 3. Adding grease to the door hinges; 4. Replacing the seals; 5. Poor contact in the door lock mechanism. Components of a car door: 1. Door body: Includes inner door panel, outer door panel, window frame, door reinforcement beam, and door reinforcement plate; 2. Door accessories: Includes door hinges, door stoppers, lock mechanism and inner/outer handles, door glass, window regulator, and seals; 3. Interior trim panel: Includes mounting plate, core panel, interior upholstery, and armrest.
The old car I used to drive also had creaky doors, and it took me a long time to figure out the problem was due to lack of lubrication in the door hinges. Over time, the lubricant in the door hinges and limiters dries up, making every door opening and closing sound like metal grinding against metal. Aging and deformed weatherstrips are another culprit, especially in summer when the rubber shrinks due to high temperatures, causing the weatherstrip to squeak against the door frame when closing. If there's a rattling sound inside the door when driving on bumpy roads, it's likely due to loose clips on the door panel or loosened window regulator screws. For a DIY fix, you can buy a can of door hinge lubricant and spray it on, or apply some talcum powder to the rubber weatherstrips to reduce the noise. However, if the door latch clip is deformed and prevents the door from closing properly, you'll need to take it to a repair shop for adjustment.
