What Causes the Squeaking Sound When Opening the Car Door?
3 Answers
Opening the car door with a squeaking sound is due to insufficient lubrication of the door's stopper. Here are the relevant details about the squeaking sound when opening the car door: 1. To ensure the pulley remains smooth and quiet for a long time, you can regularly add lubricating oil for maintenance every 2-3 months. 2. Open the door to its maximum angle, clean the grease and dirt from the stopper arm, stopper pin shaft, and connecting bracket surfaces, then apply an appropriate amount of grease to the upper and lower surfaces of the arm. 3. Wrap some tape around the door latch. 4. Check if the door seal is aging and promptly clean the dust and rainwater from the gaps in the seal. 5. If the seal is aged or damaged, it is recommended to replace it directly.
I've encountered the issue of car door squeaking several times, mainly due to lack of lubrication in the door hinges. The lubrication on the pivot shaft dries up over time with daily door openings and closings, just like a rusty bicycle chain creaking. Another common cause is a faulty door limiter - that small component controlling the door's opening angle will make clicking noises when worn out. Also, don't overlook the door seals, especially on cars five or six years old, as hardened aging seals can produce squeaking sounds from friction with the door. The most troublesome issue involves internal door problems, possibly loose window regulator brackets or foreign objects stuck inside. Last time my friend's car had this issue, he solved it by applying grease to the hinges himself. If the noise persists, it's best to have a professional mechanic inspect it by disassembling the door.
Door squeaking is quite annoying, especially the sharp screeching sound when leaving for work in the morning. The most common cause is lubrication issues - door hinges and latches lose lubrication over time, just spray some WD-40. Another frequent culprit is worn or deformed door check straps, causing jerky movement and clicking sounds when opening. Weatherstrip aging is particularly noticeable in winter as cold temperatures harden rubber, leading to friction noises. Sometimes the noise originates inside the door, possibly from loose screws or detached soundproofing material. My old car once had this issue - after cleaning sand and dust from door gaps and applying white lithium grease to hinges, the noise disappeared. I recommend checking these moving parts during monthly maintenance.
