Toyota Prius V excessive road noise issue possibly related to new rear wheel bearings on Toyota Prius V

Some Toyota Prius V owners report experiencing excessive road noise, particularly after changing the rear wheel bearings. This loud noise may be linked to the front wheel bearings, especially if it continues despite the rear replacement. Additionally, some owners find it challenging to distinguish between road noise and other potential sources of loud sounds, such as tire, wheel, or drivetrain issues. Front wheel bearings can be prone to failure, with some needing replacement as early as 40,000 miles, often producing noise that increases with speed. While changing tire brands can sometimes exacerbate road noise, other factors like wind noise, engine noise, or debris hitting the undercarriage should also be considered. Furthermore, the noise levels can vary based on throttle input and road surface texture, with full throttle potentially leading to increased noise that diminishes at cruising speeds. Therefore, if excessive road noise persists, it may be prudent for owners to inspect the front wheel bearings and evaluate other contributing factors.
