Getting into 4hi shouldn't be much of a problem, as by adjusting the 
engine speed a little so that you have momentary lack of torque to the 
transfer case, it should slip easily into 4hi from 2hi. Unless you have 
automatic hubs or have already locked the hubs in, this may be pointless 
anyway because when you stop to put the hubs in, you might as well go to 
4hi while standing still, or maybe better yet while just starting to 
move. I always fully stop to get into 4lo and usually shut off the engine 
while doing it. There's no synchromesh in those transfer case gears. 
Getting out of either 4hi or 4lo requires, at least for me, the kind of 
process Bill describes, or in some cases, backing the vehicle up 30 feet 
or so while putting a little pressure on the lever. But again, when I 
come out of 4lo, I shut off the engine to get into 2hi from N. It seems 
to me that if you think about it, at least with an auto tranny and with 
the engine running, one gear is turning and the other is not, and you're 
trying to finesse one into the other. Tough to do. Why is that gear 
turning if the tranny is in N ? I don't know, I guess its because there 
is so little resistance that the tranny is still turning its output shaft 
even in N. Ever start your car up in N and have it still want to move a 
little?
All right you guys, jump all over me!
