front drive shaft spinning in 2wd

I have an 87 yj all stock running gear, stock vac actuator and all, when I drive down the road in 2wd my driveshaft spins, but my tc is locked in 2wd. Is this normal?

It'll probably spin a little bit due to the friction of the oils in the transfer case.

When parked, can you roll under your Jeep and turn the front shaft freely when you're in 2WD? This is the way the NP231 should work, unless you have a locker in your front axle.

When I bought my Jeep, the front shaft wouldn't spin freely when in 2WD. When I rebuilt the Transfer case, I found that the mode spring had been left out, likely by whoever did some sorta maintenance on it. I replaced the spring with the rest of my rebuild, and it spins freely by least it did until I put in an Aussie.

....I'm not smart, but I can lift heavy things.......
