Ok here it is, Please dont make fun of me. I have a NP203 in my truck. I dont know jack about 4x4 truck and im just now starting to learn. So im reading and reading. What im having a prob with is, I hear you guys talking about full time and part time. I really have no clue what yall are talking about. It there a link out there somewhere that will have all I need to know about 4x4's and transfer cases? Like I was told that I have a NP203 and that its full time. But that its probly been swaped to part time Ok now that just messes me up. I ave no clue what that means? Or what is better? So someone hook me up with a link or some info on this. Thanks for any and all help.
