cluncking noise.

Went for a 31 mile ride this morning on my Specialized Allez triple and noticed I get a cluncking noise when I am free wheeling. It is more noticeable in certain gears. The bike is 2011 model so may be it needs a good service as it has done 5500 miles. So, what can the noise be?

Shot hub bearings, damaged axle, or shot freehub if you are unlucky.

Thanks. Will take it to my lbs for further investigation, soon. When I tried it on my stand earlier, I noticed that the cassette wobbles a bit when it is turning.
