Default Growling sound coming from the front. Help!!!

I have a 2003 GMC Yukon XL Denali with 150k miles. I'm experiencing growling sounds coming from the front (what seems to be front left). It happens on acceleration, deceleration and coasting. I can even hear it going about 5mph, just a lot slower growling. Front wheel bearings have no play and were replaced about 30k miles ago. I also tried to move the CV's by hand and don't seem to have any play. Could it be a output shaft bearing or something internal to the diff or transfer case? Thank you in advance for any suggestions...

Question Growling sound

I have an 03 Yukon too and am starting to hear a slight growl in the engine when I am idling. I'm thinking that maybe my A/C idler pulley bearing is going bad, or some other idler bearing under the hood. Its very feint right now but seems to be getting a little louder each week. Anyone care to comment?
