Hearing a weird humming, grinding, or growling noise from the back of your Scion xD? Feeling vibrations in the steering wheel or seat? It might be time for a new wheel bearing and hub assembly. This A-Premium part is a direct replacement specifically for the REAR wheels of the Scion xD from 2008 to 2014. It's a complete, ready-to-install unit that includes the bearing, hub, and a built-in ABS sensor, so you don't have to buy pieces separately. It's a 5-lug design that fits your existing wheels and lug nuts perfectly. This thing is built tough to solve common problems like noise, vibration, and grease leakage from old, worn-out bearings. It's constructed from high-grade GCr15 and 65Mn steel for serious load capacity, handling both radial and axial forces like a champ. The wheel studs are sturdy steel, and the unit comes pre-greased for long life. It replaces OEM part numbers like VKBA7622. Installation is straightforward for a mechanic, and it comes with A-Premium's reliable one-year unlimited-mileage guarantee for peace of mind. If your xD is showing those classic bad bearing symptoms, this hub assembly will get you back to a quiet, smooth, and safe ride.
