If a front wheel exhibits both radial and axial movement, what would be the MOST likely cause?

Explanation:
Movement in both radial and axial directions indicates excessive clearance in the bearing assembly. The wheel bearing holds the hub to the axle and allows smooth rotation with minimal play. When the bearing is loose, the inner race can move relative to the outer race in multiple directions, causing movement perpendicular to the axle (radial) and along the axle (axial endplay). This dual-direction play is most characteristic of a loose wheel bearing. While a worn axle shaft, hub, or even a worn bearing can cause problems, the specific combination of radial and axial movement most reliably points to a loose wheel bearing.
