How to Fix a Door Hinge Failed Hinge Knowledge_Tallsen 1

Expanding on the topic of door hinge damage in daily vehicle use, there are several common reasons for these failures. One of the most frequent causes is improper door opening, leading to severe wear of the door hinge shaft or hole.

When the door does not open properly, there are noticeable symptoms. The door may not be able to open and close freely, and when closed, the door lock may not close properly, resulting in a rebound phenomenon. Sometimes, while driving, the door may unexpectedly spring open by itself. These issues are typically caused by excessive force used when opening the door, resulting in damage to the door limit device and hinge, or accidental causes that lead to the deformation of the door hinge.

To address this problem, a simple remedy can be applied. Using a wooden block with specific dimensions (length 100mm, width 40mm, and thickness 15-20mm), the door can be opened to a certain angle, and the wooden block can be inserted into the deformed loose-leaf hinge. By closing the door with the appropriate force, the deformed hinge can be corrected. It is important to avoid using excessive force during this correction process to prevent overcorrection. The wooden block can be removed after inspection, and repeating this procedure several times will help eliminate the fault.

Another common reason for door hinge damage is a severely worn hinge shaft or hole. This issue is characterized by the lower corner of the door without hinges drooping, causing the door to rub against the door frame. The door lock may also become misaligned, making it difficult to open or close the door. Additionally, the gap on the hinged side of the door may be wide at the top and narrow at the bottom.

The root cause of this failure is the prolonged use of the vehicle or insufficient lubrication, resulting in significant wear of the hinge shaft or hole. As a result, the gap between the hinge shaft and the hole becomes too large, causing the door and the door frame to displace relative to each other.

To troubleshoot this issue, adjusting the lower hinge of the door should be the first step when the door sags due to hinge shaft or hole wear. The adjustment process is similar to the one used for correcting the fault caused by improper opening of the door. If the issue persists, the upper hinge of the door needs to be adjusted. Loosening the screws on the side of the driver's cab, where the loose-leaf hinge on the door is fixed, allows for adjusting the size of the door gap. In most cases, this adjustment eliminates the fault. This method can be applied to repair various vehicle door hinges.

In addition to these troubleshooting methods, it is essential to emphasize the importance of proper maintenance. Regularly lubricating the door hinges can significantly reduce wear and prolong their lifespan. When moving the vehicle, the door should always be closed to avoid any accidental damage. Furthermore, it is crucial to exercise caution when opening and closing the door, ensuring that excessive force is not used, as it can lead to the door opening too wide.
