Shimano 2008 XT 775 cassette rear hub ratchet pawl failure

Failure noticed as noises, then ratchet mechanism siezed/jammed (rather than turning freely in both directions).

This is the 2008 model, with an aluminum axle and 14mm fixing bolt, rather than the older model with steel axle and 10mm fixing bolt.

The larger inside diameter likely means thinner pawls and/or support.
