It is difficult to determine whether the wheel bearing is broken without further inspection. However, some common signs of a broken wheel bearing include a loud grinding or growling noise coming from the wheel area, excessive play or looseness in the wheel, and uneven tire wear. It is important to have a professional mechanic inspect the vehicle to accurately diagnose the issue and determine if it is indeed the wheel bearing or another component causing the problem. **

The time it takes to change a wheel bearing can vary depending on the make and model of the vehicle, as well as the experience level of the person performing the task. Generally, it can take anywhere from 1-3 hours to change a wheel bearing. This includes the time it takes to lift the vehicle, remove the wheel, brake caliper, and rotor, and then press out the old bearing and press in the new one. It's important to follow the manufacturer's recommended procedures and use the proper tools to ensure the job is done correctly. **

The correct term for the ball bearing of the rear wheel of a bicycle is the "hub bearing." The hub bearing is a set of bearings that allow the wheel to rotate smoothly around the axle. It is an essential component of the wheel assembly, providing support and reducing friction for a more efficient ride. Regular maintenance and proper lubrication of the hub bearings are important to ensure the longevity and performance of the rear wheel. **

Driving with a broken wheel bearing is extremely dangerous and should be avoided at all costs. A broken wheel bearing can cause the wheel to seize up or come off while driving, leading to a loss of control of the vehicle. It is recommended to stop driving immediately and have the wheel bearing replaced as soon as possible to prevent any accidents or further damage to the vehicle. **

The TÜV (Technical Inspection Association) in Germany allows for a maximum wheel bearing play of 0.5mm for passenger cars. This means that when the wheel is jacked up and the mechanic tries to move it from side to side, there should be no more than 0.5mm of play in the wheel bearing. This specification is important for ensuring the safety and stability of the vehicle while driving. **

It depends on the specific needs and preferences of the rider. For road cycling, a lightweight and aerodynamic wheel with a smooth tread may be preferred for speed and efficiency. For off-road or mountain biking, a wider and more durable wheel with a knobby tread may be better suited for handling rough terrain. Ultimately, the choice of bicycle wheel will depend on the type of riding and the specific requirements of the rider. **

For a bicycle, it is generally recommended to use cone bearings. Cone bearings are more commonly used in bicycle hubs and bottom brackets because they are easier to adjust and maintain. They also provide a smoother and more efficient rotation for the wheels and pedals. Industrial bearings, on the other hand, are designed for heavier loads and higher speeds, which are not typically necessary for a bicycle application. Therefore, cone bearings are the more suitable choice for a bicycle. **
