Okay, I think i can help here a little, as i just went through this whole discovery process last month.
First you turn the manual hubs on the front wheels CLOCKWISE to engage them.
Next you have to be moving forward SLOWLY with the transmission IN GEAR (1st or 2nd) when you push the "Transfer case" stick into either 4H or 4L. (I had some trouble getting used to NOT pushing in the clutch when i first started doing this)
When you do this, the "4 wheel" light should come on in your speedometer cluster (unless the light is burned out)
When going back into 2wheel, you just need to pop it back to 2H with the transmission in either 1st or second.
After you are done, you should rotate the manual hubs on your front wheels COUNTER clockwise to disengage them if you are going to be driving in 2 wheel for a while.
If your 4wheel is reletively unused, your transfer case will be a bit hard to shift until it loosens up a bit. It just takes a bit of practice.[addsig]
