I agree w/ Dave, if u have a part time system, u should not use 4wd on dry pavement, if it's full time 4wd, there are 3 couplings that shift torque to different axles to to allow wheels to spin at different revolutions, and u should not experience the 'driveline wind-up' ,or torque bind. If u do, the system needs to be inspected for problems.

there is a vacuum switch on top of the transfer case it applies vacuum when the truck is shifted in to 4 wheel drive . if you connect it to direct vacuum you front axle will be engaged all the time

First thing to test is to see if the front driveshaft is getting engaged from the transfer case. With the vehicle in 4x4, and engine shut off, and in park, crawl under and try to turn the front driveshaft by hand. The driveshaft looks like a pipe that runs from the transfer case, located just behind the engine/transmission, to the front differential. If it rotates by hand, there is a problem with the transfer case. Some Jeeps have a vacuum actuator on the front diff that slides a collar inside the axle tube to engage it. I will watch for you findings, and you can leave me another message, and I will be happy to chat back with you on your findings.
