1996 F150 Bearing (outer) nut
 

Does anyone know what size socket or what kind of tool is used to take off the rotor on a 1996 F150 4X4? I got the auto hubs off and the guts out, and there is a wheel retaining nut left and none of the hub sockets seem to work. I am replacing the auto hubs with mile marker manual hubs and need to replace the wheel/bearing retaining nut.

Thanks
