loud roaring in right front tire.

i have a loud roaring between the center of the vehicle and the right front tire. i am trying to determine if it is the wheel bearing, or something in the transmission. tranny is not slipping, but roaring is very hard to pin point. i strongly feel it is the wheel bearing but dont know how to troubleshoot

try doing some hard cornering at speed, such as freeway offramps, fast cornering in empty parkinglots, etc.

Listen for a change in the tone, pitch or volume of the roaring noise when cornering. Bad wheelbearings will often change the noise they make when subjected to side-loads.
If it does change, the wheel bearings are definitely at fault. Consider changing the bearings for both front wheels at the same time.
