I have a 96 GMC 3500 and I had the exact same problem. The small pinion support bearing went south. Never knew there was a problem with it until I got to approx. 72 - 75 mph and was getting a strange small vibration. I believe all those rear ends in that time period had a small whine to them anyway. I know a few guys that have complained about the same deal. If you catch it quick enough you havent ruined any of the other bearings in the housing. I didnt take mine to a dealer to have it fixed. The prices were outta sight. Went to a truck repair shop. Freightliner dealer took care of it nicely and saved some bucks!
