Rear wheel bearings and hub assemblies are essential components of your vehicle's suspension system, ensuring smooth and safe driving. However, like any mechanical part, they can wear out over time, leading to various issues.
Rear wheel bearings are vital components that allow the wheels to spin freely while reducing friction and supporting the vehicle's weight. They are typically made of heavy-duty metal and consist of inner and outer races with ball or roller bearings in between.
Hub assemblies combine the wheel bearing with the wheel hub, which mounts the wheel to the vehicle. They also integrate other components, such as speed sensors, ABS rings, and brake rotors.
Ignoring a faulty rear wheel bearing or hub assembly can lead to costly repairs or safety hazards. Watch out for the following telltale signs:
