Front end wheel resistance??

[Kevin.womacks]

Hey All,
Recently my '05 automatic has felt like it has some sort of resistance in front wheels.
Even in neutral, it doesn't roll freely.
Steering seems fine. No shaking at high speeds.
The sound is more or less a quiet, low hum. Like knobby tires sound on highway.
I also thought it sounds and feels a little like gearing down.
P.s. 4wd not engaged.

I am about to check transmission fluid levels.

Thanks for any advise.

Do the wheels feel warm after a run? What about the front diff?

Wheels are good. Already checked brake calipers. They are good.

Any noise? The front propshaft CV joint is worth checking too, the small boot splits and it fills up with mud.
