    Heres what its doing. Dang thing doesn't want to stay in 2-hi. I move the shift selector up there, and it will stay for a little while, but now, almost every time I accelerate, it'll work its way back down into 4-hi, creating a hellacious grinding noise. I thought it might be a bad linkage adjustment, but after playing with it for an hour, I finally removed the damned thing (linkage), and no go- it still does the same thing. 4-hi and 4-lo work perfect. If I put it back in 4-hi, which is where it seems to want to be, I don't get any more grinding. Any ideas on what could be causing this??

    Mine moves, but not enough to put it in 4hi. Let me know if it's the forks. Maybe mine needs a rebuild...

    Ok.. got it fixed! When I popped the rear tailshaft housing off, the snap ring that holds the shaft in place fell out. Got a new snap ring, popped it in, and no more problem as of yet! Stick still moves a little bit, but its always done that. I'm just glad I didn't have to go any further into the T-Case!
