Well, I took it to a bike shop and they replaced the bearings, so it seems okay now.
The only thing, after taking the cassette off, the freehub has massive gouges out it from the cogs, which are so bad it will likely be needing replaced before these bearings go.
There were also gouges out it inside where the pawls are, down to really crap sealing I guess.
I have read that some people have tried to put a steel pin on the splines to help save the alloy from any more damage, like AC/Novatech do.
I think that’ll be my next project as the 13t will soon be spinning freely around the hub if I don’t fix it soon!
I have the newer QR with the convertible axles.
