Can I replace or service bearings in LG1 DH integrated 7 speed driver/cassette units?

Answer:

Bearings in our LG1 DH 7s drivers are not replaceable. While it may be tempting to attempt, e*thirteen generally recommends replacing entire 7s cassette unit itself. 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 integrated 7s drivers come with new pawls and springs, it's best to replace the whole unit.
