What Causes the Squeaking Noise When Opening and Closing Car Doors?

[DiKevin]

The reasons for the squeaking noise when opening and closing car doors: Due to years of use, the door hinges and limiters experience wear and tear, and dust accumulates in the gaps, causing vibration interference during the door operation. Solutions for the squeaking noise when opening and closing car doors: 1. For issues caused by hinges, lubricating oil can be applied; 2. For problems caused by limiters, clean the grease and dirt from the limiter arm, limiter pin shaft, and connecting bracket surfaces, then apply an appropriate amount of lubricant to the upper and lower surfaces of the arm. If the car has been in use for a while, it's important to check whether the door seals have aged, as seals are rubber products that can gradually deteriorate and break over time, leading to noticeable wind noise and friction sounds for passengers. If the seals are aged or damaged, it is recommended to replace them directly.
