Give this a read. Transfer Case If that doesn't answer all your questions, or you have more after reading that, post them up, and somebody I'll help you out.

I'll give you a quicky so you arent overwhelmed by the info given so far and end up over looking some important things that could cost you your axles or T-case. Part time basically means only to be used off pavement or in low traction situations, hence the Part (of the) Time. it transfers part of the power to the front wheels (via the transfer case) for off pavement use, if you have a np242 that has a Full Time 4wd this can be used either on or offroad but will be clearly marked FULLTIME. Try using part time at only appropriate times under appropriate conditions, using the part time onroad or where there is a hard surface that has sufficient traction for on road use can cause the axle to bind when turning and other bad stuff that could eventually lead to either leaving your rig stuck somewhere, pockets empty from repairs, or both.

ok that kinda makes sense, but im not seeing the difference between part time 4X4 and 4-HI; is the difference that in part time 4X4 it only gives the front end partial power and the majority of power is still in the rear? while 4-HI gives all 4 tires the same amount of power?

They're the same thing, just different ways of saying it.

Kinda.

It sounds like you have a NP242 in your jeep. Which means you have part-time, and full-time 4wd. Part-time is what every 4wd vehicle has in it. Now full-time 4wd is different, sorta. Full-time 4wd uses a limited-slip differential in the transfer case to allow the needed slippage your drive-train needs when on a dry surface, to keep it from binding up.




Edit: I hope that's useful, and makes sense.

In parttime 4x4 there is no slip between the front and rear axles. They will be solidly connected VIA the chain drive in the t-case. This means that the front and rear tires are turning at the same speed at all times and when you turn the wheels there will be binding and something will break if you have good traction. In fulltime the is a differential action between the axles that allows for different speeds front and rear and it can be used at all times on any surface.
