What hub? It takes a 10mm to remove the dial assembly on the locking hub, a 12 mm to remove the hub body istelf, a 54mm to remove the bearing hub, a 14mm to remove the spindle and a 17 to remove the bearing cap/steering arm to get the knuckle off. The diff is removed with a 12mm and the pinion flange is removed by a 32mm(?) socket.
