Whenever I need to work on a bearing nut in a truck like that I take a suitably sized screwdriver with sharp edges on it and place the tip between the nut and the hub ID. The long axis of the screwdriver lays parallel to the axle shaft. By twisting the screwdriver so one corner grabs the nut and the diagonal corner digs into the ID of the hub, the nut can be turn off or on by turning the hub/wheel assembly. Simple hand pressure is normally enough to get the screwdriver to catch and do its work . Very much like a sprag clutch element in function.

Long ago I made a wrench out of a suitable diameter exhaust tube by beating it into a hex and drilling a cross hole for a handle to fit through, plenty strong enough to remove and replace the bearing nuts.
