1983 K5. I have to use 4wd often to get up to my cabin. Keeps popping out of 4wh, which I'm reading is not uncommon. The lever seems to ride in a gait, and if I hold it to the right it holds it in 4wh, but the lever won't stay there on it's own. What's the deal, is the gait supposed to hold it from slipping out? Am I missing a spring?
 
should be a 208 t-case and shifter IF ALL STOCK . . .

if so there a shifter bolted to the body of the blazer and a link rod down to the t-case . this has some adjustment . . . but lots of times at our vehicles age it can be worn body bushings letting the body flex a lot more than stock newish and poping the lever out of the selected range.

so check for both miss adjusted and or bad body bushings .
 
Thanks. Yes it has the linkage rod but it looks to be a bear to get up there with wrenches.. The adjustment seemed OK to me because neutral and 4wl are indexed in the right spot on the gate. It does not pop out of 4wl.
 
OK, will check the mounts. I'm new to 4x4 running gear, is it the shift lever mechanism that holds the transfer case in gear, or is it like a manual transmission that holds itself in gear? Or is the lever pulling it out of gear when the mounts move?
 
Usually the lever pops it out. the lever is attached to the body, not the t case. if the t case moves more than it was designed, the lever doesn't move with it, popping it out of gear.

It isn't the only potential cause for this but it is the easiest to check
