I think you have the vacuum axle lock which does get 'stuck' in 4x4 or 
leaves the front wheels engaged to the T-case usually due to a leak in a 
vacuum line.

I would start by examining the vacuum switch on the passenger side of 
the front axle to see if the lines have fallen off.  If everything is OK 
down there, then I would look under the battery next looking for 
'corrosion' spots on the lines caused by battery acid.  There also is a 
round vacuum ball down there that can get cracked.

Having the front axle live won't hurt anything, it just makes the 
steering a bit heavy and costs a couple mpg.  I have manual axle locks 
(hubs) and I routinely lock them up if I expect to see snow and just 
drive in 2 wheel drive until I need to ****ft.
