What is a wheel bearing? And what does it do in a car? A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction.

Wheel bearings have a very important job – enabling the rotation of your wheels. They make sure your wheels run smoothly with minimal friction. They also maintain correct wheel tracking and can even play a role in providing your vehicle's drive systems with wheel speed sensor signals

We found significant play in the bearing, which can lead to a soft brake pedal. Brake rotors are held in alignment by wheel bearings. If you have a faulty or loose wheel bearing, the rotor will wobble on its axis. This wobble causes the rotor to push the caliper piston into its bore

Each wheel is equipped with a wheel bearing, a set of steel balls or rollers held by a cage in a ring of metal called a “race.” As the wheels spin, they create friction and heat. Wheel bearings help to reduce the friction, heat and protect the wheels and tires. The wheel bearing lies inside of the hub assembly.
