My noise has evolved. I've had a couple of instances where I felt a shuttering in the car. The first time, I thought it was a misfire but no cel and it cleared up after I stopped at a light and took off again. Yesterday, I was driving on the interstate and felt it again but it cleared up once I stopped at the bottom of the exit ramp and started moving again.
Per previous suggestions, I ran the car jacked up. My videographer felt the recorded noise was more from the hubs rather than the diff. The bearings are new. My plan is to replace both axles.

Note: It's quiet when rolling except when it's not.
