Trying to identify what spring & pawls I need

KT hub branded by Vitus, kt-h5er-2227

Had an episode of the hub not disengaging properly and forcing the cassette to turn while freewheeling… Despite me not believing a bad spring or pawls could cause this, it’s a cheap fix if it does work.

Failing that, any ideas which freehub I need? It’s a 3 pawl system, wide pawls with the spring running across the middle of them all. HG freehub.

Struggling to find with any certainty what I need…. Except maybe going back to hope hubs!
