This is probably a real newby question, but what is a simple, foolproof way of knowing that both parts of the 4WD system are actually actuating (i.e., without getting under the car and examining the component parts)?
If I jack the front end up and spin one front wheel, the other front wheel turns in the opposite direction, so I assume that the front axles are engaged. But how can I know that the front driveshaft is getting hooked up? And am I right in my assumption about the front axles?
Thanks,

Try t with one front wheel on the ground. If in 4x4, you should not be able to move the wheel far without major force.
