Roaring 10 bolt

My 8.5" 10 bolt has developed a fairly loud roar running on the dyno.I'm running a Auburn pro with 4.56 gears.I had planned to change the gears to a 3.90,should I plan on a differential change at the same time or do I need change the bearings on the Auburn.I'm running 29" tires on a 01 Tahoe dynoed 618 hp today.

Check out diameter (circumfrence) of tires, you might have clutch chatter on the dyno. Does it do it on the street?
