Default Transfer case popping out of 2-hi

Hey guys. Now that my '67 scout 800 is running well I should probably address my transfer case.

I think it's a d20(?) I'm not sure. I have a four speed manual with a 196 engine. Dana 44 in rear and 27(?) in front.

So seeming randomly while cruising in fourth gear my transfer case will pop out of 2-hi. It never pops out of lo. And I can't really get it into 4-hi. 4-hi barely seats and just pops out almost instantly.

Currently I have the stick bungee'd to the seat to keep it in 2-hi. But it will still pop out and grind until I push the clutch in.

I've searched through the forum and found a few threads but none really went into to much depth/ never updated on a solution.

I have the service manual, and it says it might be bent forks,a bad spring or bearings.

Has anyone experienced something similar? What did you do?
I want to drain the trans oil and refill it. Not sure if that would help.
Can I just use 90 weight gear oil?
