Rear end grinding/rubbing noise. I have a video..

Ok off an on i've mentioned in posts my rear end of my 5.9 makes noises above 65mph like gears rubbing or something. I finally recorded a video of it.

Listen for it in the video its very obvious.. Deep pitched rubbing or vibrating sound almost.. Does it everytime i go above 63mph and it stops above 73-75mph. I tend to take streets when i go somewhere instead of the freeway to avoid those speeds.

Anyone have any idea what makes this noise ? You notice in the video im going 60mph and its fine, and when im done talking i give it some gas and it starts to make the noise right at 65mph. I put the phone down and then i have to slow down because of traffic and you will notice its then completetly silent, but then as i pick up speed it comes back.

Turn the volume up to hear it better, you can also hear the loud rumbling background noise my rear is making on top of the vibrating noise, you might need headphones to hear it best, speakers you cant really hear it

Need to tear into it to see what you find, your 5.9 has an aluminium housed dana 44 which doesn't have the greatest reputation. My older brother has had a handful of v8 zj's and has had several problems with carrier bearings in the aluminium axle.
