Can I replace bearings in e*thirteen freehub bodies?

Answer:

While the bearings in e*thirteen HG, XD and MS freehub bodies are replaceable, we generally recommend replacing the freehub body unit itself rather than just replacing bearings. This is because pawls, springs and to an extent driver bodies are wear-and-tear items. Pawls wear, springs loose their force and pawl pockets on the driver body can wear and open up over time. Since all our drivers come with new pawls and springs, it's best to replace the whole unit.
