Dismantled a 203 NP T-Case to get the HI-LOW gears from it. Now have the old brown truck in the garage, pull the T-Case to get to the gears.
I just in the last couple of years, about ten miles ago, installed a rebuild kit and a part time kit in the box. Never knew it jumped out of four low, never tried it in four low, shifter was froze up LOL
I found out when I built the double sticker kit. No amount of force could hold it in, it`d bust a wrist if a person tried holding it in. Bad thing is, the gears and slider looked just fine.
I believe that is what happens when a person runs in four low on hard pack, then tries to get it to full time high and the drive train is bound up, instead of backing up for a few feet, just kick it hard enough, it`ll pop out.
