2000 dodge neon loud humming noise

As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.

When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.

While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.

The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).

Does anyone have any insight or thoughts to what is causing this? Thanks!

Front Wheel Bearing and I question repacking the bearings as they are sealed.
