So I would have moved it to the correct groove, that would make sense. Where it was before didn't look like it would do anything.

"Sounds like all the parts aren't there.Does the 4 wheel drive work right? An 86 should have a big flat gear visible as soon as you pop the cap off."

Parts missing is a genuine possibility, however, the 4wd did work pulling me out of a ditch after a distracted driver knocked me off the road a month ago. I can't remember seeing a big flat gear, but like I said, it was months ago when I had it apart. I believe there are a couple 4x4 systems for that truck in '86. One automatically actuated, and one manually turning the hubs. Mine's automatic.

Thanks for the responses guys.
