Audi spindle knuckle with wheel bearing, genuine OEM part 4K0505431C for the left rear. This used component includes the pre-installed wheel bearing, ready for installation on Audi models equipped with 2.0L, 2.9L, and 3.0L engines (gas, mild-hybrid, and plug-in hybrid variants). The spindle knuckle connects the suspension upright to the axle, while the wheel bearing allows smooth wheel rotation. A failing bearing typically produces a humming noise or vibration that changes with speed.
