    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:confused: 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.

    Try reading some of that. With the 203 Full Time you are always in 4 wheel drive, converting it to part time allows you to take it out of 4 wheel drive. Frees up gas mileage a little and is easier to turn the front wheels.

    Someone else jump in if im wrong.

    It's definitely best to have a part-time equipped NP203; if not you have a full-time four wheel drive, which bites you at the fuel pump. Here are the Mile Marker part-time conversion kits: http://www.milemarker.com/4x2conversion.html
    I don't remember how to tell if you already have a part-time kit installed, but a forum search will return your answer. See, no one made fun of you... yet.

    Full time also puts unnecessary wear on parts that otherwise wouldn't be turning, like u-joints.

    I have locking and unlocking hubs. Does that mean that I have part time?

    Just put in Hi and unlock the hubs. If the truck moves you got a part time conversion. If you have full time 4wd you have to have it in HiLoc with unlocked hubs.

    Yea, that´s what I meant, the test works in 4wd Lo too. If you have a full time 4wd NP203 the center differential in it causes all the power to go to the unlocked frontwheels and the truck doesn´t move until you put it in 4wd Hi/Low Loc and lock the center differential. A stock full time 4wd doesn´t have freewheeling hubs so yours is probably converted to part time.

    Yeah you can also just look under it and see if the fornt driveshaft is spinning while the trucks moving but it sounds like its partime
