Hi Skyshroud,

I'm sure those hubs will be fine, they look to be in much better shape than mine were (see below). As has been suggested, I removed and cleaned the axles, cones and bearings first. Then I washed, cleaned and then lightly polished the hub bodies before reassembling with new grease and ball bearings (both very cheap). Then I built them into a new pair of wheels and they've been fine since.
