Front drive shaft spins all the time

Thought I was stuck in 4wd as I could see Frnt DS
spinning all the time. Jacked up all four corners and both
2wd and 4wd work normal but if you grab and spin a Frnt tire the DS
spins freely in 2wd. In 4wd the DS spins a quarter turn then the
T-case stops it.

Now some backround- initialy I had no vacuum to the CAD I replaced
the vacuum switch at the t-case with a known good switch and now
have vacuum to the outboard VAC line in 2wd and no Vac to either
in 4wd.I tried swap the Vac plug so as to pull the diafgram to the
other side but did not help. How could I tell if Ive been converted to
a solid axel? will I do damage driving around like this?

Thanks

The vacuum should switch between the 2 ports (2 and 4 wd). That is what moves the disco ring back an d forth. There is still a problem with the vac system. Good luck.

You won't hurt anything if it was converted to a one piece axle.

If you have the stock 2 piece with the axle disconnect it should look like this inside the disconnect housing on the front axle.
