If the growling sounds like you are driving on rumble strips then it's the bearings. Very common. You may also feel a slight vibration. I just did mine this spring. Driver side was very loud but no play in it. I replaced the passenger side because it was just as old and it's always a good idea to replace bearings in pairs. Make sure to use a quality brand like Timken, what I used, or another quality brand. Cheap wheel bearings are junk in a short amount of time.

The inner part of the cv axle isn't a conventional joint. It is a two piece joint that slides in and out to adjust for suspension travel so it should have play in and out. The axle cv joint is the outer part of the axle next to the wheel bearing. I can't imagine that causing a growling noise. The outer cv joint clicks when it's bad.
