My rear hub was self-tightening while riding. Taking it apart i noticed that the freehub was loose. On removal I see that the freehub retaining bolt appears to have a bearing surface on it. It is the one on the left in the pic below. I've not seen one like that before. That bearing surface is knackered - the outer edge has totally worn away.
The freehub has no part number on it. It is off an Parallax XT M737 hub. Freehub is 7-speed and may be the original.
Are these bolts with a bearing surface available (can't find any). Can I replace it with a standard retaining bolt - the rest of the freehub looks similar (though shorter) than a more modern one? Or do I need to replace the freehub (cup surface looks ok)?
Any advice appreciated.
