Does replacing a car door have any impact?

[VonAnnie]

There are mainly two impacts: 1. Paint color difference: If the car door is replaced at an external repair shop, there may be a color difference issue with the repainted door compared to the original factory door. If you need to replace a car door, it is best to go to a 4S shop for replacement. 2. Poor sound insulation: If the door is not replaced through official channels, problems may easily arise in assembly techniques or details, leading to air leakage or increased noise during high-speed driving, which can degrade the car's sound insulation and affect in-car comfort. Precautions after replacing a car door: 1. Door gap width: Observe whether the gap width of the car door is uniform and whether the surface is smooth, otherwise abnormal noises may occur. 2. Door sealing: Check whether the sealing of the car door is intact, otherwise issues like rain leakage or air leakage may occur. 3. Door opening and closing smoothness: Repeatedly open and close the door to check for smooth operation or abnormal noises.
