Is It Serious If the Small Metal Block on the Wheel Hub Falls Off?
2 Answers
The small metal block on the wheel hub falling off is not a serious issue. Below are specific explanations regarding the small metal block falling off: Function: The small metal block on the wheel hub is used for tire dynamic balancing. If it falls off, it needs to be reinstalled. The wheel should be removed, and a lead block of the corresponding weight should be hammered into the same position. Then, perform wheel dynamic balancing again before reinstalling the wheel. Impact: If the block is not replaced after falling off, it will affect the driving comfort of the vehicle. Prolonged driving may lead to vehicle jolting, deviation, abnormal tire wear, and increased safety hazards. The car wheel is an integral unit composed of the tire and the wheel hub. Due to manufacturing processes, the weight distribution of various parts of the wheel is uneven. When the car rotates at high speed, dynamic imbalance occurs, leading to 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.
A few days ago, I noticed a small metal block on the wheel rim had fallen off. I didn’t pay much attention at first, but when driving on the highway, the steering wheel started shaking, and the car felt unstable. That small block is used to balance the wheels, and losing it can affect smooth driving. If left unrepaired for a long time, it can cause uneven tire wear and even accelerate damage to the shock absorbers or suspension system. I quickly went to a tire shop to have the wheels rebalanced, which cost less than 100 yuan, and the problem was solved. I’d like to remind everyone not to underestimate it—daily driving safety comes first, and it’s good to regularly check the condition of your wheel rims.
