Is this normal? (cassette wobble)

I have recently noticed that when I pick the back end of my bike up and spin the tire forward...I can see a slight wobble in the cassette(while the wheel is spinning and the cassette is still)...i have taken the back wheel off...taken the axel off and inspected for warpage and it appears true...the wheel also appears true...put it all back together and it s till does it. I cant feel a difference while riding. I also notice that when I pick up the back end and spin the tire really fast I get a rythmatic wobble in the whole bike...like every revolution i get a slight "tug"

Mind you I can feel NONE of this while Im riding....but is this normal?

I found this out when a loose lock ring finally let go and my cassette fell apart on the trail

I think a loose lock ring "wobble" looks a lot different than what he's talking about. The slight gyrating of the freehub body is pretty normal, even on some higher end hubs.
It happens on 100 dollar wall mart bikes to 8,000 super bikes, depending on the spec. Like everyone else said, don't sweat it as long as everything is in otherwise proper order.

The clicking you're hearing is the pawls passing over the ratchets. It's perfectly normal. So called "advanced" hubs like Hope, Chris King and DT Swiss actually make much more noise.
