Body vibration: If the bearing is severely damaged, causing increased clearance, noticeable body vibration may occur during high-speed driving. 3. Unstable driving: When the front wheel bearing is excessively worn, it can lead to unstable vehicle movement and erratic power delivery during high-speed operation. Below is relevant information: The main functions of hub bearings are to support weight and provide precise guidance for wheel rotation. They bear both axial and radial loads, making them crucial components. Traditional automotive wheel bearings consist of two sets of tapered roller bearings or ball bearings combined. The installation, lubrication, sealing, and clearance adjustment of these bearings are all performed on the automobile production line.
