NSK Wheel Bearing P/N:40BW05CG40
Help keep the front wheels rolling smoothly with the NSK wheel bearing 45BWD03, a front wheel bearing from a global leader in rolling bearing products. It is a direct-fit replacement for many vehicles, among them the 2002-2013 Hyundai Sonata, 2002-2013 Kia Optima and 2005-2017 Hyundai Tucson; see the "Vehicles it fits" section for the full list.
A wheel bearing lets the wheel rotate with low friction and helps support the vehicle's load at that corner. Signs it may need replacing include a humming or growling noise that rises with road speed, a rough feel at the wheel, or noticeable play when the wheel is rocked. If a worn bearing is the cause, this part replaces it. Diagnose the cause first, because tires and other components can produce similar noises. See the "Vehicles it fits" section for engine-specific details.
