how do i tell if i have manual hubs or the vaccum hubs that work off the switch automatically? i have the switch on the dash but when i lock it in 4x4 it does not do anything but when i manually lock the hubs it feels like it will pull the world. Whats the sure fire way to tell if they are electric or not. Im going to wisconsin in a month and this ******* has never driven on snow or ice and id like it on the fly.


what could it be that is bad?
