I have a 97 5.0 AWD with ~85,000 on the odo. If the windows are down or a door is open I can hear a nasty clicking/ticking metallic noise coming from under the body when the Ex is rolling slowly while idling. It seems to be coming from the area of the transfer case. I suspect (hope) it is a universal joint, but there seems to be no play if I tug on the driveshafts. Any ideas?
