This used OEM left rear spindle knuckle / wheel bearing housing, genuine part number 4M0505431AJ, comes from a donor Audi. It houses the wheel bearing and supports the suspension, steering, and braking loads on that corner. A failing knuckle often causes a persistent wheel-bearing noise or vague steering. This is the left rear unit, not the right.
