The diff seems to be whining in the Vette while under low load in 5th and 6th (I’m guessing its whining in all the gears but its only noticeable in those 2). It stops whining if im off throttle and under heavy accel (could be that the exhaust is too loud for me to hear it). I did replace the trans and diff fluid today and its still the same :(
It sounds like this, but its much more quieter than that:
I’ll take it to a Vette specialist in Indy this week for a final diagnosis. If it is the diff, I will just drive it as is for a while and see if it gets worse.
Interwebs suggest its around a $1000 to get it rebuilt. Welp.... I would also need to take the entire rear end out of the car to remove the diff. Seems like fun times ahead!
Anyways, have a good weekend Oppo.

Likely a pinion bearing.

It’s unfortunately a common issue on these cars. Daender knows a guy who has been through 2 of them.

Every time I see someone talk about a job like this and see it’s about a grand to repair I think “that’s it? Not bad at all.” I'm not sure if that's a good or a bad thing.

This. I was lucky that mine never went wrong.
I had windows, fuel pump, and BCM go wrong, but not the rear thankfully.

Thats a grand if I remove the diff myself , labor is another 700 to 1000 :/

As Demon-Xanth said, it’s likely the pinion bearing:
As as the guy in this video discusses, you can see how to check for it and it might be cheaper to just get a replacement than to rebuild what you have:
