What are the functions of the door limiter?
The role of the door limiter is very important, mainly in the following three aspects:
1. Limit the maximum opening of the door:
The door stopper can prevent the door from opening too large to ensure driving safety.
2. Keep the door open:
When the car is parked on a ramp or in a normal wind, the door limiter keeps the door open and prevents it from being automatically closed, thus protecting the door from damage.
3. Protect doors and body:
The door limiter can also protect the front border of the car, avoid contact with the body metal, and reduce the damage to the body.
The installation method of the door stopper is fastened to the car body through a mounting bolt, and the limit box is fastened to the door through two mounting screws. When the door is opened, the limit box moves along the limit arm.
There are different levels of structure on the limit arm, the elastic rubber block will have different elastic deformation, and at each limit position point, it can play the role of limiting the door.
The door stopper can be divided into rubber spring type, metal spring type and torsion spring type according to the way the limiting force is provided. According to the type of friction, it can be divided into rolling friction and sliding friction.
The door stopper is broken. Is it necessary to repair it?
Must be repaired
The door limiter is broken and must be repaired . The main function of the door limiter is to limit the opening and closing range of the door, prevent accidental opening resulting in collision, and keep the door stable in bad weather or on ramps. If the limiter itself breaks or loses resistance, it must be replaced in time to ensure the safety and stability of the vehicle.
The role of the door stopper and its performance after damage
limiting door opening and closing range : The limiter limits the maximum opening of the door to prevent it from opening too wide.
Keep doors stable : The limiter prevents doors from closing automatically on ramps or when it's windy.

replacement of limiter : If the limiter itself breaks, it is recommended to go directly to the repair shop or 4S shop to replace a door limiter.
check other faults : if the limiter has no resistance, it may be because the limiter itself is broken, it is recommended to go to the repair shop or 4S shop to replace a door limiter, or check whether there are other faults before repair.
Specific operation steps
Apply lubricating oil :
Prepare special lubricating oil.
Apply the lubricant to the door stopper, making sure to apply evenly.

Replace the stop :
Remove the damaged stopper.
Install the new stopper on the car to ensure that it is securely installed.
Test whether the new stopper is working properly.
Other possible solutions
Tighten the screws : Use a socket wrench to tighten the screws on the tie rod type stopper to restore its function.
