What lubricant should be used for door stoppers?
2 Answers
Door stoppers can be lubricated with specialized door hinge and track grease to reduce friction and wear on mechanical components, thereby extending the service life of the stopper. Here is more information about door stoppers: 1. The door stopper is fastened to the car body with mounting bolts, while the stopper box is secured to the door with two mounting screws. When the door is opened, the stopper box moves along the stopper arm. 2. Due to the varying heights of the structure on the stopper arm, the elastic rubber block undergoes different degrees of elastic deformation. At each stopping position point, it effectively limits the door's movement.
I've been driving for over twenty years, and door limiters need regular lubrication, otherwise the squeaking is annoying and accelerates wear. The most reliable choices are silicone-based lubricants or white lithium grease, which adhere well without dripping, avoiding the mess and interior contamination of regular motor oil. First, clean off dust and rust from the limiter with a soft cloth, then apply a thin layer of grease. Open and close the door a few times to let the lubricant penetrate. Don't use WD-40 as a long-term solution—it's only a quick fix, as prolonged use can degrade components. Lubricate every six months to keep door hinges smooth, extend the door's lifespan, and save money and hassle. If the limiter is already stuck or making unusual noises, it's likely due to dried-out grease. Delaying action may require replacing parts, which is more troublesome.
