growling sound in 08 V6

I have an 08 double cab 4X4 and have a growl coming from the front end I believe. I rotated the tires changed oil and diff fluids, greased drive shaft. CV joint boots are in good shape. Put front end up and it seems tight, I couldnt get front tires to wiggle (checking bearings). I do think the carrier bearing on the drive shaft is worn. It is definately in the drive system and not the motor as it does it when ¥ou are coasting etc. any body else have this problem or know what it might be. Thanks in advance.

 

Wheel bearing? does it make the noise all the time, only when turning, only when braking?

how many miles do you have on it?

 

its got 117,000 all highway. I use it for my work. no hauling, just driving

 

Does it go away when you put it in 4wd?
