I'd suggest pulling off the diff cover and having a look around. If you haven't done the fluid then its probably time to do that too

Theres a magnet in there that will collect pieces if they get broken, but you can spin a wheel and look for broken teeth..

Does it sound at all like a card in spokes??

 

It does some what But like 10x louder lol. Im going to have to check that out thanks for the info I will post here after i get this done will be in the next couple of days thanks

 

If its that kind of noise I'd say wheel bearing for sure, if its consistant. If it is, the race could get welded to the axle/housing if it goes on too long.
