If you are trying to figure out if its still in 4x4? (which seems to be what you are getting at) You can jack up both front wheels and spin them, if the driveshafts spins the T-case is unlocked.
As i mentioned earlier in the post, there is no lockouts (pm kickstand for actual name of that type of axle) but most call it a live axle.
If the driveshaft doesnt spin the t case is still engaged. As i mentioned before it may just be stuck, I never had any luck getting those T-cases in or out of 4lo very easily.
