That was we can maybe eliminate the driveshaft & rear end.
Also, while your coasting in neutral, rev the engine a bit & see if the sound of the squealling changes.

Does the sound change if you're turning left or right?
If you put the brakes on, does the sound change?

I'm just trying to get a little closer to what's causing the noise.
The sound changes like when you go over a bump or a dip and if your at a certain pitch meaning not level it will stop
