Wheel bearing? Diff.? ...what am I hearing

[tjnavyblue]

Hi,

For the last hundred miles I've been hearing a 'woh woh woh' coming from what sounds like the passenger side rear tire. It seems to be getting louder. I don't think its the tire or wheel - I just had them mounted and balanced by a reputable shop. The 'woh' sound happens about 2.5 times per second at 60 mph. That seems fast but each 'woh' is really quite disinquishable. They are farther apart when slower, and I don't really hear them below 30.

Any thoughts? Is it the diff? Wheel bearings maybe? I don't even know where to start. ..

Thanks in advance.

Wheel bearing, had one go out like that. Exactly how I described it.
