So, a hypothetical question here, and no flames please... I'm embarrassed to not know this, or have forgotten this, but...
Say you'd driven your Jeep a lot. In fact so much that the transmission was almost completely shot... as in first, second, third gears working intermittently if at all.
And say you needed to have that transmission replaced.
Can you go unlock the hubs and put it in 4wd and have anything good happen by driving it to the shop nearby in a 4wd gear rather than relying on the main gears?
Step-by-step procedures appreciated if so... and please, stop all that laughing!
