Wheel bearing noise is always there and doesn't change with/without gas pedal.

Pinion bearing changes with gas on/off. Carrier bearings change just slightly and can go silent if you match RPM to the engine.

That's why I went ahead and got the bearing stuffs (once they decided to get here and stop travelling the entire state), it seems to be there at any speed but when going slower it is harder to hear and the faster you go the more you notice the noise there.  Plus it's the cheapest and easiest thing on the whole list of things that it could be rearend wise. I am sure it needs it anyways. I know the front bearings weren't factory, someone changed those out at some point but what are the odds that they did the rears too.
Now just gotta find someone to do the work, got someone in mind that I need to talk to but he is hard to catch.

If the rear pinion is bad, you only hear it when your foot is on the gas, usually starts around 60-70 and peaks around 90km/hr. It will hit a harmonic frequency and quiet down after a fashion.

Bearings will be louder when you turn.

CV will show up the easiest if you go in reverse and turn, it'll make all sorts of fancy sounds like clicks, etc.
