while in drive, engage the 4wd then shift into neutral for 2 or 3 seconds and shift back into drive. it works for my ram.

Your front hubs are automatic locking hubs, and the gears are hard nylon. These hubs break very easily, therefore causing you to lose your front wheel drive in 4 high, or 4 low. If you replace the hubs with "WARN (name brand) " manual locking hubs, you will never have the issue again. Of course, you will have to get out of the truck and manually lock the hubs, but they are metal gears, and much more durable. I've personally seen the issue several times, and changing the hubs has resolved the issue every time.
SOURCE: When in auto hubs the 4 wheel drive doesn't work
They are operated by vacuum. Check to make sure the vacuum lines are connected and not ripped or anything. If that checks out fine, remove the vacuum line from the hub and apply vacuum to the hub, if the hubs lock then the problem is in the vacuum line or switch.

Hello , chances are the 4x4 transfer motor/solenoid on the case either has no power , or has failed. I removed mine from my 2004 Explorer , dis-assembled and replaced the nylor washer and re-assembled and she works.
