Hello all of youse, I ll have to agree with tbone on this one. I had
same problem with my 4x4.
It works on 4x4 low no problem, my 4x4 high was not getting in right. I
had to move the truck little bit then shift it in high, on some days it
works, on some days it doesn't work. I end up replacing my 4x4 shift,
it was just rust that makes it hard to shift in, don't ask why I had it
fixed with new shifter. Now it shifts so smoothly.
That part cost me 250 and its worth my work. I just saved myself
fortune not to take it to shop.
Just use your haynes manual booklet. Most of information is right there
with some troubleshoots.
