Does wheel hub scraping require balancing?

[JulietteLynn]

Whether wheel hub scraping requires balancing depends on the situation: 1. If the degree of wheel hub scraping is not significant, dynamic balancing may not be necessary; 2. If the wheel hub scraping requires replacement with a new one, then dynamic balancing testing is needed. The wheel hub is the central part of the wheel, mounted on the axle to support the tire, typically cylindrical in shape, and usually equipped with bearings to reduce friction. Common wheel hubs include steel rims and aluminum alloy hubs. In the manufacturing of modern automotive components such as the body, wheel hubs, engine, and transmission, the use of composite materials is increasing. Composite materials are a new type of material, and wheel hubs made by selecting appropriate materials and processing methods offer advantages such as high strength, lightweight, good toughness, corrosion resistance, and wear resistance.

I often scrape my rims while driving, and I used to be really nervous about it. Later, I found out that minor scrapes don’t necessarily require immediate wheel balancing. Once, I scraped the curb while parking, leaving a big scratch on the edge of the rim, but I didn’t feel any steering wheel vibration when driving. The mechanic said such surface damage doesn’t affect balance. However, if the rim is severely deformed—like getting a dent from hitting the curb—then wheel balancing is a must. My neighbor’s car had a deformed rim once, and at 80 km/h, the steering wheel shook like a massage chair. It was only fixed after rebalancing. So, the key is whether the rim is deformed. If not, save the money and don’t bother.

Does wheel hub scratching require balancing? It depends on the extent of damage. If there are only minor scratches or paint chipping on the wheel rim edge, wheel balancing is completely unnecessary as such damage hardly affects wheel balance. However, if the wheel hub is deformed, such as becoming out-of-round due to hitting a pothole or being squeezed, wheel balancing is definitely required. Last year, my car scraped against a stone on a rural road, causing a small dent in the left front wheel hub. Initially, I didn't pay much attention to it, but when driving on the highway, I clearly felt steering wheel vibrations. A check at the repair shop revealed uneven tire wear, and it took a 40-yuan wheel balancing service to restore normal operation. It's advisable to feel the wheel hub with your hand after each scrape to check for any dents or deformations.

As a long-distance driver, I believe wheel balance must be checked after rim scratches. Once while delivering goods, my wheel rim scraped against a guardrail. At first glance, it just lost some paint, so I didn't pay much attention. Later on the highway, I noticed something wrong - at speeds over 70 km/h, the steering wheel developed a slight vibration. At the service area, inspection revealed slight deformation on the wheel rim edge. The mechanic said this kind of invisible deformation is most dangerous, and long-term neglect can cause uneven tire wear. Now whenever my rims get scratched, I always test drive at low speed to feel for steering wheel vibrations, and after driving over two hours, I carefully check for abnormal tire wear patterns. Any issues get addressed immediately.
