The 4-wheel-drive is not engaging. The Indicator lamp is lit on the dash. The Front drive shaft is turning but there is no power getting to the front wheels, therefore, the front wheels are not turning. No noises are coming from the transfer case. The truck is shifting easily in and out of 4-wheel-drive. It seems to be something with the front axle but I am unsure. I am trying to meet the 200 minimum characters so I am able to submit this. Sorry for all the extra words.
