After repacking the hub the axle still has vertical play on the drive side. After adjusting the cones I can move the axle around inside the freehub body. If I turn the axle it feels rough but if I pull on it from the drive side or push on it non-drive side it will turn smoothly. I don't know what to make of this. I have overhauled a number of hubs, but this is my first one with a freehub. Help!
