| Component | Function |

|---|---|

| Wheel Bearing | Supports the weight of the vehicle and reduces friction between the wheel and axle |

| Wheel Hub | Connects the wheel to the axle and allows for steering and suspension |

Benefits of Wheel Bearings and Wheel Hubs

Enhanced Vehicle Stability:

- Properly functioning wheel bearings and wheel hubs ensure smooth and controlled movement of the wheels, reducing vibrations and enhancing overall vehicle stability.

- According to the National Highway Traffic Safety Administration (NHTSA), faulty wheel bearings can significantly increase the likelihood of accidents.

| Benefit | Description |

|---|---|

| Reduced vibrations | Smoother driving experience |

| Improved control | Enhanced stability and handling |

| Reduced safety risks | Less likely to experience accidents |

Extended Tire Life:

- Precise alignment of the wheels facilitated by healthy wheel bearings minimizes uneven tire wear, extending their lifespan.

- A study by the Tire Industry Association found that approximately 25% of premature tire failures are attributable to improper wheel alignment.
