First 1998 is not very old.
Second, that should have shift on the fly in it. That means it has an inter axle disconnect in it and you can shift between two High and four High without stopping. You pull the lever or push the button and the transfer case will shift into four high and the front drive shaft starts moving. At the same time there is a switch that activates the front axle interlock. This moves a collar that locks the right hand axle together and you are now in four wheel.
To shift into four low is different. You cannot shift into that on the fly. You have to stop, put the transmission into neutral, shift into four low and then shift into drive/reverse. Reverse the process to go back to four high or two high.
