08quadram is on a distinguished road

Have you check to make sure you have enough vacuum at the actuator motor. You may have plenty at idle, but running down the road you may not. I used to have several Jeep Grand Wagoneers and everything on those ran by vacuum. My '83 required that the vacuum actuator at the front axle engage first, then it would travel to the transfer case and engage that. Something to check out.
