Exclamation 1989 D21 Only Moves in 4x4

I'm having an issue with my truck in which it only wants to move when 4x4 is activated. It does not matter which type of 4-wheel-drive is activated. When 4x4 is in the neutral position, the car revs and does not move as if it is neutral. I have had my dash disassembled for a while now, and I think I may have been driving the thing in 4Hi for quite some time now unknowingly.

The vehicle is a 1989 D21 with 4x4, the V6 engine, and a manual transmission.

I'm thinking the rear end or something in the transfer case might be toast? Any ideas?

there is an actual "neutral" position for the 4wd selector. you need to actually push it into 2wd. however i forget what the pattern looks like. i think its all the way forward. sometimes its a little finicky trying to get the x-fer case into position. you can try it with the truck not running to help alleviate the fear or doing something wrong. but as long as its not in gear when youre futzing with the transfer case stick all should be just fine

Put it in 2wd. Neutral is literally neutral. Transfer case is after the tranny so youll go nowhere.

LOL...I did that once too. The previous owner had switched out the shifter knob for some fancy (and unmarked) knob. I also felt like a dunce.

Worse...then I realized I had bought a four-speed. Crap. I didn't keep it very long, I can tell you that.
