here the thing- I was cycling home last week and noticed that the rear wheel wasn´t feeling particularly smooth. When I was coasting for example the chain would be twitching. I took the rear wheel off and noticed that the cassette was very wobbly. The ring holding the cassette on was perfectly tight so I took the cassette off and the problem was with the freehub body (which holds the cassette on the wheel). The freehub body was quite wobbly so I think this is where the problem lies. The wheel axle (edit I mean skewer) was perfectly straight and could be withdrawn from the wheel without problem. So it looks as if the problem lies with the wheel bearings but it did not seem that the locknuts were particularly loose. As I have not played around with this wheel since I bought it a few years ago I am thinking that the problem is due to wear.
So before I take the wheel bearings apart can any of the more experienced mechanics tell me what the best course of action is. Of all jobs on bikes playing with wheel bearings I find to be the most frustrating and time consuming. So any suggestions here as to things to check would be very much appreciated (taking it to the bike shop though is not an option for me so please don´t suggest that).
