Place vehicle in 4wd (high or low). This will hold the front drive shaft still for the rest of the test. Jack up the front end of the vehicle. Remove the actuator. Have a buddy spin the right front wheel while you use a long punch or screwdriver to try to manually engage the diff. The left front wheel should spin in the other direction if the diff is good. Also before you check the diff you need to grab the front driveshaft and make sure it is locked, If it spins freely when the truck is in park and in 4wd with the front end raised then problem is in transfer case. If you can't make the diff engage manually with punch then the problem is in the diff. If front diff engages manually then the problem is the actuator. Hope this helps..

You cannot pull the front differential and drive the vehicle. The wheel bearings are tied into the front axle, and won't properly lubricate if not installed.

I had this same problem a few years ago. In my case I didn't use the 4 Wheel Drive very often and the tranfer would hang in 2 Wheel. I fixed mine by tapping on the transfer case with a hammer while my wife switched back and forth from 2 Wheel to 4 Wheel.
