Should a damaged wheel hub be repaired or replaced?
2 Answers
A wheel hub with a gap caused by impact needs to be replaced. Introduction to wheel hubs: A wheel hub is the rotating part of the wheel that connects the tire's inner rim to the axle via spokes, serving as the central metal component that supports the tire. It is also known as a rim, wheel ring, or wheel disc. Wheel hubs come in various types based on diameter, width, manufacturing method, and material. Types of wheel hubs: Wheel hubs, also called rims, employ different surface treatment processes depending on the characteristics and requirements of different vehicle models. They can generally be categorized into two types: painted and chrome-plated. For standard vehicle models, wheel hubs prioritize functionality over appearance, with good heat dissipation being a basic requirement. The manufacturing process typically involves painting, where the hub is first sprayed and then baked, offering a cost-effective solution with vibrant colors and long-lasting durability.
As an experienced driver, I have to say something about the wheel rim being chipped. Safety always comes first. Although the chip on the rim may look small, the wheel rim bears enormous force when driving. The chip can cause uneven weight distribution, making the car shake severely while moving, which is especially dangerous at high speeds—the tire might burst or the rim could completely fracture. I suggest you immediately check the location and size of the chip. If it's on the edge and as small as a fingernail, you might consider repairing it, such as taking it to a professional shop for grinding and welding—but only if the rim is made of steel, as the strength of alloy rims is hard to guarantee after repair. If the chip is large or near the center hole, don’t hesitate—replace it outright. Rims can cost anywhere from a few hundred to over a thousand yuan, but safety is priceless. Although repairs save money, they might not last long and could pose hidden risks. It’s best to have a repair shop test it with a balancing machine—safe driving is no trivial matter.
