Hello everyone. Sorry I have been away a while.
Just replaced my 7.5 with a 8.8 Track Pack rear end with Torsen differential. It's amazing!
All my gear and axle noise went away, but one noise stayed.
This noise WAS present before the rear end swap. Just a lot easier to hear now.

It is like a scraping, whirling noise right around 75-80 MPH. I'm up and down on the gas keeping it in the noise on the video.

It is so hard to hear at lower speed, I can't promise it is there. May be a tiny bit, but so hard to hear.
With gas pressed only. Not on coast.
Speed dependent. Not RPM.
Car isn't hesitating. Transmission fluid changed by a legit and trusted dealer a few hundred miles ago.
Car doesn't seem to care it is making noise, but I sure do.

I've heard everything from torque convertor not locking correctly, to wheel bearing, to u joints. I'll take any advice.

Anyone who could shine some light on this would be extremely appreciated.
Thank you for your time,
Steven

It's hard to tell on the video, but to me it sounds like a wheel bearing.
