Wheel bearing noise?

[scottc]

Hi guy's.

I was driving through the timber sction of Bunnings the other day, and when I slowly drove off, I noticed a slow sqeeling type noise that stopped when I stopped. It was fairly loud in the enclosed space of the loading area. I kind of put my foot on the peddle to see if that made it stop, but it didnt, only when I increased speed did it die down.

Is this the symptom of a wheel bearing? If so, what is the best way to find out, and how can you tell which wheel?

Also, how much does it cost to replace your wheel bearings?

Sorry for so many questions!
Cheers guys.

Scott.
