My cheapish bike has a noticeable wobble in the freewheel cluster. Easy to see when the rear wheel free-spins and you look down at the cluster. I'm sure it's not a bent axle because the wheel is tree and doesn't wobble at all. Also, almost every bike I've got has some wobble in the cluster. Seems endemic and I'm just curious as to why. People rarely have cause to open up clusters but generally they have gaps in the number of bearings used ie there might 30 odd little ball bearings in a race but room for 40. Given that there's an outer and inner race in the clusters, I'm wondering whether this contributes to the wobble, allowing a little bit of lateral movement mechanism turns.
Wheel bearings, cups and cones all in good shape.
I'm going to try packing a few more bearings in the races with maybe only a 2-3 bearing space left.
This previous post from someone else shows the exact problem with video footage, but I don't think any of the replies get to the cause.
Anyone got any other theories?
