Have someone ride in the passenger seat and see if they hear it from the same direction. Noises can be very difficult to pinpoint as the sound travels.
Frequently the center bearing will sound to the driver as if it is coming from the right front area. Or you could ride in the passenger seat with someone else driving since you know the sound, and then if it appears to come from the right front, pursue that area some more, but if it now sounds like it is coming from the left or somewhere else look to the center of the car. Possibly the center bearing, a dry differential seal, the rubber mount for the center bearing or something along those lines. HTH and good luck.

I removed and inspected the outer wheel bearings, found nothing. Did not inspect the inners. Bearings were not loose before removal. Ordering a new set of bearings anyway. Brakes are decent and noise is unchanged during braking. Swapped the tire with spare, no change.
Sorry for the messy post, it is very late. Any help is appreciated, I am stumped.
