Expert Reply:

The part of a hub/drum assembly that makes contact with the electromagnet, the armature surface, cannot be machined. If the surface is deteriorated you'd do well to replace that hub.

The link provided will show you all hub/drum assemblies which you can sort using the filters on the page. Be sure to match your bearing set, bolt pattern and axle weight capacity when choosing a new hub.

You might also refer to the linked article on re-packing bearings.
