Can anybody point me to an online guide or offer instructions and tools list for changing axles?

Thanks

Pretty similar to the 10mm 🙂

I’ve become quite an expert at changing the axles since converting mine to 12mm. I’ve snapped/bent three axles in 6 months.

thanks messiah, I’m a bit worried about these reports, but unfortunately don’t have an option unless I change hubs 😕

So, basically I need to go through the hub service procedure?

Remove free hub and axle end caps. Drift axle out out non drive side, 1 bearing will come with it. The fit new axle and bearing with (i think) 22mm socket. Refit end caps and freehub.
