Common symptoms of a failing wheel hub assembly include a grinding or humming noise that increases with vehicle speed, illumination of the ABS warning light, or uneven tire wear. Replacing a worn hub restores proper bearing preload, eliminates noise, and ensures the ABS sensor signals correctly. It is recommended to use a new axle nut and torque all fasteners to specification during installation.
