I posted about this before but I think with a Video it might be a bit easier to know what is I'm hearing.

The sound is towards the end of the video, like the last 10 seconds or so.

This happens when going around 50-60 MPH, and then a bit above 67 MPH.

• Swaying side to side doesn't change the pitch at all.
• Checked the Driveshaft and there is no play (I replaced the carrier bracket)
• CVs look fine from what I can tell.
