Because it is an electronic 4x4, the transfer case will only shift when the computer tells it it is OK.  Do you have a manual, or an automatic?  I know with mine, it shifts alot easier if you let the clutch out while the trans is in neutral.  Try either putting it in neutral, or rolling slowly while in neutral, that might help.

is it a stickshift type 4x4 mechanism?  or is it an electronic pushbutton? 

i have the 2000 v6 4x4 5speed.  I shift into 4x4 in NEUTRAL with the clutch engaged.. i dont know why, i just thougth it'd be the safest way.   the safest way is to park and then do it, in neutral probably. 

as far as the "shift on the fly" thing goes.   if you want to do that.  i'd suggest pulling over first...engaging the 4x4 and then going.  then when you're driving you can take it out....or put it back in....once you've initially engaged it that first time, it will be easier to shift in and out untill you roll the truck backwards like six feet.

i dont remember why that is.

mine will make a nice CLUNK sometimes if i try to engage when rolling....i just dont like that, so i do it parked now.  it has been like that since i test drove it when it was new. 

even after they replaced my front hubs once.

i think they all do it.
