How to Fix a Stiff Car Door That's Hard to Open?

[NadiaDella]

Difficulty in opening a stiff car door is often caused by rust or sticking in the door hinges or limiters. The door hinge is an area that is easily overlooked during maintenance. It's essential to regularly apply grease or oil to prevent rust, unusual noises, or poor movement. Apart from the above reasons, the following factors can also make it hard to open the car door: 1. High friction between the door handle lock and the lock post: If there's significant friction between the vehicle's door handle lock and the lock post, it will require more effort to open and close the door. Prolonged use can lead to poor lubrication, making the door difficult to open. Use a screw loosening agent to lubricate the door lock post. 2. Misaligned lock post: An improperly aligned door lock post will inevitably make opening and closing the door more strenuous. Adjust the large gear wheel and M8 to correct this issue.
