Does removing and reinstalling the car door have any impact?

Removing and reinstalling the car door can lead to car depreciation, malfunctioning window functions, and affect the body's rigidity. Replacing with aftermarket doors: If an aftermarket door is used as a replacement, there will be differences in precision compared to the original factory door, and the materials used will also differ, resulting in varying levels of rigidity. Typically, the sheet metal of aftermarket doors is slightly thinner, and some anti-corrosion processes may not meet the original factory standards. This could lead to potential issues later on. Since car doors are not considered wear-and-tear parts, any replacement is sufficient reason to suspect that the vehicle has been involved in a collision, classifying it as an accident vehicle, which will depreciate the car's value. Post-replacement feedback: Replacing a door is definitely not as good as the original. Some car owners who have replaced their doors report issues such as large gaps, noise, and possible looseness, which can still have a certain impact on the body's rigidity. This is also why many car owners regret replacing their doors.
I do think removing and reinstalling car doors can have some impact, especially if not done properly. I've seen many DIY car owners at auto repair shops who ended up damaging the hinges when they couldn't put the doors back, resulting in loud wind noise while driving, poorly compressed seals, and water leakage during rain. And those electrical connectors—if not aligned properly, the power windows can become jerky. I recommend not attempting this lightly and finding a reliable professional to handle it instead. Otherwise, imagine the horror of driving with a loose door lock midway. Older car doors are even more fragile; replacing worn parts with OEM components during reassembly can reduce future issues—safety first, after all.
I have a friend who is a car modification enthusiast. He has removed the car door several times for repainting, but after reassembly, there are always minor issues. For example, the door hinges wear out, making the door closing sound muffled and heavy, with vibrations transmitted into the cabin. He mentioned that the sealing pads age quickly, the air conditioning cooling effect is slightly worse, and fuel consumption increases slightly. If the door is not aligned properly, the wind resistance at high speeds becomes greater, and the noise is unbearable. It's recommended to check if the clips and screws are tight and use professional tools to adjust the position, which can reduce risks and extend the door's lifespan. If all else fails, take it to a 4S shop—spend some money but save the hassle.
From a technical perspective, removing and installing car doors requires precise operation; otherwise, it may affect functionality and durability. If the door is slightly misaligned during installation, the hinges will bear uneven stress, leading to abnormal noises or poor closure. Reversed wiring can also blow fuses. Professional mechanics use calibration equipment to ensure proper alignment and prevent major issues, but DIY attempts are costly and risky.
