for people to help you, you are gonna ahve to elaborate on your exact problem if you can. It may only be the vacum lines again or it could be an encoder or maybe an actuator. I don't know all that much but have been watching the responses on most of the threads and trying to learn myself. if you can include your year and which 4x4 switch you haver it may help (manual on the floor or electronic). also what may help is if you can do your own searching in the forum by using the search this forum at the toip of the page (I'm not saying your stupid but I almsot missed it a few tiems) and search for 4x4 problems or something like that. There are plenty of posts that explain many different problems and how to fix them.

If you have no knowledge in this, I would suggest you take it to a good mechanic.

Without knowing the basics, you can't troubleshoot.
