i believe those are vacuum controlled on top of the transfer case is a plug with 3-4 vacuum lines going to it,you will need to take it out and see if the check ball is stuck if it is it needs to be replaced

Check for a blown fuse. use your manual to find fuse location. you can remove the shift motor and engage it manually, you need to remove front driveshaft.

Two things maybe your problem:1 .Front axle actuator to engage 4wd is not releasing. 2. Front axle u-joint needs replacing. Lift car on jacks with front end off ground. Then spin tires by hand as fast as you can and see if you hear the noise and where it is coming from ( spin in both directions).
