As stupid as it may sound but:
 

Whats the correct way to engage 4x4? I have a 1996 4.0L with AW-4 and NP242 transfer case... ?
:mellow:

stop, put it in neutral then pull the 4wd lever to either 4wd H or 4wd L

Its better to engage while moving. If in to 4hi- shift under 45mph. If into 4Lo then 2-3mph

are you serious?

You can do it while moving, just make sure your wheels are not slipping...

i know he is right about the 2-3mph, but what about the 45mph??? if you engage then wont it screw somethin up"

Im pretty sure 45 wont do anything bad... For some reason I am wanting to say the maximum speed is 55.

wow so you can engage into 4wd hi going between 45 and 55mph

yup, in our manual, it say's tranny in neutral and shift into 4hi between 80-90kph, so 45-55mph.

but yeah, for 4lo, 2-3mph is best, but it's still ok to do while not moving at all.

aight cool might have to try is sometime........not, well thanks for the info, hope that helped the guy who started this thread

Ok, heres an example for you... Your driving on a paved country road in the middle of a windy winter day... You then turn down a road that is covered in drifts and realize that turning on the 4WD is a good idea... You would want to do this while you are moving... if you stop, you will sacrafice the momentum you had and have a better chance of getting stuck.

A more perfect example is driving in sand...

yeah except i live in moblie alabama and i havent seen snow in 13 years lol but sand is a good example down here

I had a feeling you lived in a snow free region... lol

haha yeah i was 5 the last time it snowed,and it melted within a few days, but sand is an issue down here at a fes spots we wheel, oh i was going down to the beach last weekend and had to do a u-turn and there was sand on the side of the road and i had to go through it to completely turn around and got stuck in 2wd, then locked it in 4wd and crawled right out! gotta love 4wd!!!

5 years old huh... Must not happen to often then lol... Rust free climate has to be nice.

yeah i was a little thing! yeah rust free is great! and it probly will never snow here again.....

My dad was wanting to buy a 4 banger MJ for a parts truck during the restoration job... The guy only wanted like 1200 or 1500 or something for the whole truck... The truck was totally rust free. I kind of wish we could of drove down and bought it. I hear Alabam is a pretty state.

yeah it is pretty pretty lol if you see the right part, the beaches are real nice, and theres lots of land and trails and country to ride on, i love it here

Last time it snowed here was about May:w00t:

I have put both of my XJ's in 4hi at 70mph, on the highway. I do it all the time. 4Lo I stop put it in neutral and then shift, if you don't most jeeps will grind depending on the linkage adjustment.

o boy! thank you everyone! :D

And does the NSS come into play when shifting? Because my NSS isn't working correctly and the Jeep doesn't engage 4wd. Yes, I'm troubleshooting some (:laughing:) problems..

Not when shifting into 4wd

you can actually engage 4-hi at any safe high way speed...

and ive always found that i dont grind at all going into 4-lo by moving at about 2 MPH, like some one else said, but then putting it in neutral while coasting, then pulling it on back to 4-lo...ive never got a grind out of it doing it that way

but i have grinded it before if i slow down to 2 MPH but keep it in gear and pull the lever back, or if i come to a complete stop with it in neutral, i still sometimes get a grind....but like i said, moving at 2 MPH, in neutral, i always get a clean smooth shift into 4-lo

and thats with both the manual in my 93 XJ, and the auto in my 04 WJ

well thats good to know

you have the np242 which is in 4wd all the time(select trac) the np231 gives you the choice of 2wd or 4wd (command trac)

242 is also a 2wd t-case. it just gives you the added option of running in full time 4wd. it has 2wd, 4 full-time, 4 part-time and 4 low. with neutral in there somewhere.
you're thinking of the 249 t-case which is full time 4wd with just hi and lo. it's the quadra-trac.
