To correctly put it in 4Lo you should be moving at only 3-5mph, put the trans shifter quickly into neutral, then pull back your T-case shifter quickly back to the right all the way, then put it back in drive. You don't really have to moving and can be stuck with wheels spinning just so long as the speedometer reads 3-5mph you should be able to get it in 4Lo.

I usually coast in neutral slowly and pull the lever with a good tug.

And of course for 4 PT and 4FT can be engaged while driving not over 40 and in a straight line.

but dont use 4PT on dry pavement, you will destroy the transfer case by making it bind

on the 242 transfer case it says in the manual "any legal speed"

this would imply you can do it at highway speeds but since we are talking a 15-20 year old vehicle it may be advisable to not do it at highway speeds

4lo however you need to be in neutral and moving 3-5mph (though i've had no problem shifting into 4lo from a stop) the key is to pull back hard on the lever to get it into 4lo sometimes i've had to give it a couple tries before the GDM lights up with part-time

So if you are going 55 mph on a 60 MPH highway, it's fine, but if you switch while doing 38 in a 25 MPH zone, your t-case will explode. :-)
