I think the servo he's talking about is the one in the transfer case that shifts it into whatever gear. I'm talking about the actuator on the front driveshaft that engages the front axle. Its about the size of a coke can on the passenger side top side of the axle. They shouldn't be too hard to change, but it would be a good idea to make sure thats the problem first. I forgot that the autotrac cases have the front shaft spinning all the time...

I have no idea what you checked. Did you check the SERVO that shifts the transfer case, or did you check the ACTUATOR that engages the front axle?

I have never heard of a servo going out on the tcase, although it woudln't surprise me. I have heard of the front axle actuator going out, often. Now which did you check?

To check the front axle actuator, pull the actuator out of the axle housing, and shift the truck into 4x4 with the key in the run position without the engine running. It should move back and forth when you switch it from off to on and vice versa. If you can stop it with your hand, it may be too weak to
engage the axle.

no need to call anybody an asshole.

Well, if the front axle actuator is working correctly, and you say the front wheels do pull in auto, it sounds like you may have something wrong with the transfer case. Not sure what though, I've never heard of a problem like this, mines manual :D Couldn't hurt to check all the connections under there. Hopefully someone else more familiar with that case will chime in....
