You have a bad setup. the reason youre hearing humming is because a lot of material has been taken off of the ring gear. You can see in your picture at the top of the tooth there are straight lines, those are called mill marks. Those should NOT be gone after 500 miles. I've seen mill marks on gearsets with 200k on them still with a proper setup. Your gearset looks like its already got at least a couple hundred thousand miles based upon the way that the face of the tooth has no millmarks and its shiny, you can almost see where there was metal exchange between the pinion and ring gear by the way it looks which is why you've got noise. All of the material that came off of the ring gear is on the bottom of that magnet and in the fluid. If you purchased these gearsets brand new, i would request the company warranty them out because i can tell you right now, these are going to be difficult to get a proper setup now that they've been worn the way they have.
EDIT: This is caused usually by lack of lubrication, excessive runout ( warped case half or ring gear ), or bad pattern / excessive backlash. Whoever setup the diff messed it up. Your backside, or coast side of the ring gear looks far better than the drive side. its got millmarks down it from top to bottom and because of the way everything turns over your coast side pattern will always be on the top of the tooth that way.
