I have searched for an answer everywhere, I have an 04 Wj 4.0 with the Selec-trac, I have recently noticed when I put it in full time 4 there is a chatter or constant clicking when I press the gas. The faster I go the faster and louder it gets. If I go like 5mph it seems to disappear. Sometimes it will do it in reverse. When I put it back in 2wd it goes away. Also sometimes it takes a minuted to switch back into 2wd. I'm thinking maybe chain? If its even coming from the case. It used to hum a little in 4wd but just recently started chattering. 135k on jeep and tcase front and rear fluids replaced. Got up under it and driveshafts look fine and no play, i had my alignment man look at it the other day while rotating tires, i didn't mention the noise but he said things looked fine as far as alignment and nothing was worn in front end. Any ideas????
