Drive axle problem??

So here's the scoop....'89 wagovan that makes wheel noise while driving. It sounds sort of like when you have mud/snow tires on pavement, I guess it's a whirring sound. I've gotten the tires balanced and rotated and this past weekend changed the wheel bearing because through my research I thought that would solve the problem. Well it didn't. It still makes that noise while driving and braking doesn't change it at all. I do get some vibration at hwy speed so I'm thinking that the axle needs to be replaced. I guess my question is if the axle would cause that noise as well or if there is another culprit? I am a novice mechanic and I know there are several jedi mechanics on here so any help would be appreciated. If there is a link for this I was unable to locate it so a steer to that post would be awesome as well. Thanks for looking and have a positive day! 8)

someone mentioned it being a bearing going bad.
I've already changed the bearing and it didn't help.
I forgot to mention that it's an automatic, so no clutch to disengage. Or would that be the same as shifting it to neutral while driving?? Thanks for your help
err duh i just noticed you mentioned that :oops:
this may be a long shot, but shift your car from D to N and see if the noise goes away. then its your ISB. (very very very common issue among our trannies)
What's the best way to check that?
