My truck is making a similar noise, but when I put it on the jackstands I couldnt hear it.

Dont hear it til i go below 25 mph, but that may be because of wind noise, but I dont feel it in the pedals the faster I go. There must be something going on in there.

If not replaced it can wear a hole in the case, cause sprockets to fail and much more.

The transfer case in the 98 is different I guess. The wheel hub bearings going bad. I have a service appt tomorrow morning to have it checked over, but didn't know if anyone would have a better idea what the problem is inside that I can tell the service technician so they aren't spending all day hunting for the answer. Kinda a long rrrrrrrr sound. The garage stated that a main bearing had broken apart sending metal throughout the rear axle and destroyed the drive system.
