Front hubs

[Cartagena Pirate]

Does anyone have front hubs on their toyota that are full time locked in. Mine are not automatic and they are not manual. They are always locked it. When I look at them externally they just have a dust cover on the center of the lug bolt circle. I'm wondering if this is common or if I have a weird one. All of the others I have seen are aisin manual or warn manual locking hubs.
