What to Do If the Small Metal Block on the Wheel Hub Falls Off?

If the small metal block on the wheel hub falls off, the following steps need to be taken: 1. It needs to be reinstalled. 2. Remove the wheel. 3. Hammer in a lead block of the corresponding weight at the same position. 4. Then perform wheel dynamic balancing and reinstall it. Below are some additional details: 1. If it is not replaced after falling off, it will affect the driving comfort of the vehicle. Prolonged driving can lead to vehicle bumpiness, deviation, abnormal tire wear, and increased safety hazards. 2. The car wheel is an integrated unit composed of the tire and the wheel hub. When the car rotates at high speed, dynamic imbalance occurs, causing unstable driving and steering wheel vibration. To avoid or eliminate this phenomenon, weight is usually added to the side of the wheel to correct the balance of various parts of the wheel. 3. Generally, these metal blocks come in two forms. The first is the internal type, where the small metal block is located inside the car tire, close to the inner edge. This avoids exposure to the outside to some extent, preventing it from falling off due to scraping and maintaining aesthetics. The second is the external type, which, as the name suggests, is exposed on the outside of the wheel. The external type may affect aesthetics to some extent.

A few days ago, my car had the same issue. After that small metal piece on the wheel rim fell off, I noticed the steering wheel shaking when driving on the highway—it felt quite dangerous. That thing is actually a wheel weight. Without it, the wheel becomes unbalanced, and over time, the tire wears out faster. I immediately drove to a nearby repair shop and had the mechanic redo the wheel balancing. They attached new weights, and the problem was fixed—the whole process took just half an hour and cost less than 100 yuan. I think this isn’t something to delay, or else one day, the car might become unstable at high speed, and an accident could happen. Regular wheel checks are also important, especially after car washes or hitting curbs, as these small weights can easily come loose.

When the small metal weights on the wheel hub fall off, the key is to address it immediately—don't take chances. I once ignored it while driving, and the car started swaying left and right on bumpy roads, giving me quite a scare. Those are balancing weights, ensuring the tire rotates evenly. Losing them can lead to longer braking distances. I went straight to a roadside repair shop, where the mechanic used tools to check the wheel's dynamic balance and then reattached new weights. It only cost a few dozen yuan—no big deal. You could even buy adhesive weights and try fixing it yourself, but it's best to leave it to professionals for peace of mind. Usually, just glancing at your wheels after parking and avoiding potholes can help prevent this issue.

The small metal weight on the wheel fell off and needs to be repaired, otherwise the driving experience will be affected. On my way home, I noticed the steering wheel shaking, which was quite annoying. These weights are used for wheel balancing to prevent the wheels from running unevenly. Just take it to a repair shop, and the workers will redo the balancing test and add new weights. The process is quick and not expensive, so don't push it and risk damaging the tires, which would cost much more. When washing your car, pay attention to them to prevent them from flying off again.
