Rotor & hub assemblies combine the brake rotor and wheel hub bearing into a single pre-assembled unit, simplifying replacement on vehicles where the two components are designed to come apart together. A worn hub bearing inside the assembly commonly causes a humming or grinding noise that changes with speed or turning, while a warped or worn rotor surface causes pulsation or vibration when braking. Browse replacement rotor & hub assemblies for cars, trucks, and SUVs to restore smooth, quiet rotation and reliable braking in one part.
