I had a bad wheel bearing recently. It was making a swoosh swoosh sound and I had Death Wobble when I hit a bump or applied the brakes at ~ 40 mph. I got two new bearing assembles off of eBay and decided to replace the axles and CV joints at the same time, again with the parts I got off of eBay, the ones I linked to above.
I didn't think my CV joints were bad, but I had noticed a variety of odd sounds from the from end: a heavy dull clunk sound on slow left turns when starting out, a creek-creek, ah, ah, ah, ah, ah, sound when making an extreme right turns as into a parking space. This last sound mimicked a bad power steering unit, which I knew was not the case.
Once everything was in place, all the sounds were gone, so I assume that my CV joints were going, and the sounds I heard were symptoms of that.
