Buick Regal whining sound while driving due to bad rear wheel bearings on Buick Regal

Some Buick Regal owners report experiencing a whining or humming sound while driving, which may indicate bad rear wheel bearings. These owners note that the noise often changes with vehicle speed and can be accompanied by symptoms such as grinding noises, knocking or clunking when cornering, a shaking steering wheel, body vibration, uneven tire wear, and the vehicle pulling to one side. Additionally, some have found that abnormal tire wear can also contribute to the noise, potentially stemming from issues with the wheel bearings or wheel hubs. It is crucial for owners to address this problem promptly to ensure safety and driving comfort, as replacing the wheel bearings can incur costs starting from $162 for parts and labor.
