Toyota Prius driver's side wheel bearing replaced due to noise during acceleration and turns on Toyota Prius

Some Toyota Prius owners report experiencing noise from the driver's side wheel during acceleration and turns, which may indicate issues with the wheel bearing. This noise could be linked to a loose axle nut, as suggested by dealers. If the noise is a grinding sound, it often signifies a damaged wheel bearing that may be dry from lack of oil or grease, necessitating replacement of the wheel bearing as part of the wheel hub assembly. Additionally, some owners are advised to replace wheel bearings in pairs—either both front or both rear—to ensure optimal performance and safety. In certain cases, rear bearing problems may stem from failed differential vents, allowing oil to seep past the wheel seal and into the bearing, leading to failure. Therefore, it is recommended for owners experiencing these symptoms to have the wheel bearing inspected and potentially replaced to resolve the issue effectively.
