The hubs are ESOF or electronic switch on the fly. They should say lock on them and have arrows indicating position as well. over time the vacuum lines going to the hubs rot and you no longer have switch on the fly. at that point you have to get out and lock them manually.
this happened to me in the snow at 1 in the morning wasnt fun considering one of the hubs was frozen.
i since switched to warn manual hubs and capped the vacc lines
works like a charm now
