I've searched for info on part time 4x4 vs full time 4x4 but not having much luck...I've heard a lot of pros and cons but not from someone who isn't trying to sell me something..sure could use some help...Thanks..

 

search around for 249 which is alltime and 231 transfer case is part time

 

np242 has part and full time, 2wd neutral and 4x4 low, great for on road and off road

 

231=

2 hi
4 hi part time
nutral
4 low part time

242=

2 hi
4 hi full time
4 hi part time
nutral
4 low part time

Part time is for optimum traction and not for dry pavement
full time is for 4wd on pavement.

Full time is good for people that drive in areas where it snows because you can drive on pavement that is not slippery. part time is not ment for that.

xj does not have the 249 that was on the zj

 

Check this thread out...similar question...minus all the BS talk.
