203 info pls

i recently purchased a 77k5 blazer with a 203 t-case.
i have a ford bronco with a 205.
? the blazer 203 only works in H-LOCK or L-LOCK. not H or L.
it just grinds. What is wrong. I here theres an adjustment.
how would i adjust it or is it toast?
the blazer came from the original owner an was taken care of. pre owner stated never used 4x4 an it looks like it wasnt. it shifts smoothly. thx for any thoughts. [img]images/graemlins/confused.gif[/img]

Sounds like a shift linkage problem on the 4wd side. Check your Haynes manual, it's pretty easy to adjust, it involves lining up the linkage with a drill bit. Give it a try.

Just to clarify, in the 4wd shift linkage there is rod for Hi-Lo and a rod for 4wd or Loc (4wd/2wd on converted cases). A good place to start would be making sure the 4wd rod is engaging properly.

Are you sure the front D shaft is installed? It won't move without it unless it's in Hi or Lo lock. Only reason I mention it is: it's a quick check, and since you just bought it, it is poss that the previous owner had it out and forgot to mention it. They may have even removed it thinking that it would save them MPG, especially since they never used the 4wd anyway. I'd look there first.
