In fact, the size of the door gap is generally stipulated by the manufacturer himself. As long as it is not an accident that causes a big gap in the door, it generally does not need to be adjusted. This situation often does not affect the driving safety of vehicles, and there will be no water inflow. It is the normal gap set by the manufacturer, and the owner does not need to worry.
If the door gap becomes larger due to accidents, it is necessary to adjust the door gap at this time. It is best to find a professional shop and a professional master, especially the installation of door hinges, which requires skill and experience. If the operation is incorrect, the door will be damaged.
