Sorry, but my solution would be to take that drive back to the dealership, if he has a warranty. This is a hands on type deal, you have to trace everthing with your hands. Now it sounds to me like it could be in the electronics. You have to go to the differential, find the vaccum lines, if equipped, some are not, then trace them back to the motor and make sure they aren't cracked or broken. I hope this solution was helpful, please rate. Thanks

If it's attached to the diff housing and not to the box on the r/f axle (if you have one) it is a vent hose. Just secure it anywhere out of the way on the firewall. Don't pull it tight or when the axle moves it will fall off again!

SOURCE: I have a 96 Jeep
1995-96 V-8 engine vacuum diagram-1997-98 V-8 engines similar; be sure to check the VECI label in the engine compartment
Also I have a GC, 1993, and I noted that besides maintaining a vent hose that is not going anywhere, just this subject with a ribbon next to the front suspension.
Hope helps (remember rated this).
