    • Embodiments herein relate to a front wheel hub assembly disconnection arrangement (1) for a road vehicle (100). The front wheel hub assembly disconnection arrangement (1) is configured to promote disconnection and outwards movement of a front wheel hub assembly (2) from a vehicle body structure (3) during a SPOC. The front wheel hub assembly disconnection arrangement (1) comprises a steering knuckle breaker (4) and the front wheel hub assembly (2). The front wheel hub assembly (2) comprises a wheel hub (7) and a steering knuckle (5) for connection to a tie rod (8) of a steering mechanism. The steering knuckle (5) is arranged on a rearward facing portion of the wheel hub (7), seen in a direction of travel of the road vehicle (100). The steering knuckle breaker (4) is arranged on an A-pillar of the vehicle body structure (3), said steering knuckle breaker (4) comprising an impact surface (4a) facing the steering knuckle (5) when the wheel hub (7) is in a neutral position. In the event of a small overlap collision, the steering knuckle (5) of the front wheel hub assembly (2) is displaced towards and collides with the steering knuckle breaker (4), such that the steering knuckle breaker (4) breaks the steering knuckle (5) and disconnects the steering knuckle (5) from the wheel hub (7) of the front wheel hub assembly (2).
