Okay time to sound like an idiot, my last jeep shift on the fly- how the heck do I lock the hubs on my 87 sammy?-

  All you have to do is look in the center of the front wheels. Theres a little knob in the middle with an arrow on it. You just grab the tab in the center of the knob and turn it until the arrow points to Lock. To unlock the hubs you turn it until it points to free.

cool- thanks for the info
