The causes of door squeaking in the Baojun 310 are: 1. Presence of foreign objects inside the door trim panel; 2. Loose trim panel or audio system; 3. Rust on the door hinges; 4. Aging of the door sealing strips; 5. Poor contact, excessive gap, or insufficient lubrication in the door lock mechanism. Taking the 2020 Baojun 310 as an example, it is a compact car with body dimensions of 4032mm in length, 1680mm in width, and 1450mm in height, a wheelbase of 2550mm, a fuel tank capacity of 30 liters, and a curb weight of 985kg.
When I drove the Baojun 310 before, I encountered a squeaky door issue, especially noticeable after car washes. Upon closer inspection, I found that the door seals had aged and hardened, and the rubber had lost its elasticity, causing friction with the door frame and producing noise. The problem worsened in cold weather because the rubber contracted even more. Additionally, lack of lubrication in the door hinges could also cause squeaking when opening or closing the doors, especially after a year or two of driving when the factory-applied grease dried up. I made it a habit to wipe the seals with a damp cloth weekly and apply some dashboard wax to soften the rubber, while also adding a couple of drops of engine oil to the hinges, which eliminated the noise. It’s also important not to slam the doors too hard, as these plastic components can’t withstand rough handling. If the noise seems to come from inside the door, it might be due to loose window regulator screws or unsecured wiring harnesses, requiring the door panel to be removed for inspection.
