4wd questions/explaination
Okay I have a 94 ram 1500 5.9L and I was underneith it the other day and just happened to grab the front drive shaft and I was able to free spin it. The truck was on 2wd and parked but is that normal? Shouldn't it be attached to something on one of the ends? I took the truck out back and tested the 4wd in the woods. And as far as I can tell it's working fine. Can someone explain?

Perfectly normal. 
Your front axle has a disconnect on the passenger side axle tube. In 2wd, that disengages, so the front driveshaft isn't spinning in 2wd. Supposed to help fuel economy, and all that...... Might save some wear on the u-joints in the shaft, but, I think that's all that it saves......
When you engage 4wd, the passenger side axle halves lock together, (which turns on the 4x4 light) and you get 4wd. If you put the t-case in 4wd, trans in neutral, you won't be able to turn the front driveshaft, without moving the truck as well.
