Hey,
I've had this Shimano Saint rear hub for a while that now has a little bit of backwards play. Meaning, it spins forward fine but I can move it slightly backwards without the cassette moving.

I'm thinking the freehub is pooched. How are these hubs for servicing? The wheel is built strong and I like the hub. I should be able to order a new freehub and swap them right??

Thanks!
