    Grinding in my cassette

    I have a fairly old shimano hyperglide cassette that I use for my single speed. When I was out tonight I noticed a grinding noise and could feel it as well coming from the cassette. I checked the cones to make sure they were not loose ot too tight, and that I have all the bearings (I greased them last week and thought maybe I messed one). The noise is louder when I coast, but is constant. It gets louder and I can feel it more at a certain point in the wheels rotation. The cassette body is tight to the hub and has no free play or side to side motion. I don't know for sure how old the cassette is, I bought it used on a bike 4 years ago. Could it be that the cassette is worn out internally? I don't know enough about this problem to be certain. And if so what are my options, or what else should I check for? .

    I just replaced my Bontrager freehub last month. When coasting (especially when on the workstand) the freehub made a growling noise. You might want to try and lubricate it by dribbling oil into it, after you remove the cassette, axle and seals. I've used a heavy oil, such as Phil Wood's Tenacious Oil.

    On the other hand, it might be time for a new freehub. I believe Shimano freehubs require a 10mm hex socket (Allen) wrench to remove. I'm guessing a new freehub will cost ~$30.
