Thanks @Simba. I took the freehub apart. There are two bearings inside separated by a spacer, so similar to the hub bearing setup. The bearings are marked '600 1RS' which matches up to the hub bearings: 12mm inner, 28mm outer. So maybe I will order 4 new bearings (might as well switch them all out) and in the intervening period work out how to get these existing worn ones out.
The freewheel exploded this time as I was knocking out the axle. Pawls and springs went everywhere. Fun times.
