So I finally got to check out the car. The axles and CV joints look good. I had the car lifted on a QuickJack, put the car in neutral, e-brake off, started the car with the clutch in and engine sounds good.
When I released the clutch (car still in neutral and e-brake off) I could hear a slight grinding sound. Put the clutch in, I hear a slight grinding sound while it is going in and it was quiet when completely in.
I put it in first gear and same sounds. In the video you can see that the wheel on the driver's side didn't spin when I released the clutch with it in first. I was along so couldn't video the other wheel.
Here is a video:

Thoughts? Throwout bearing? I'd love to debug before dropping the transmission so I can order parts.
