...in your picture, it appears you have not disassembled your freewheel to access these spacers. You don't really need them on the bub, to space the freewheel a little farther out. Nor do you really need that spoke protector thing. Just service your hub as you were planning to do, and lube the freewheel by dribbling some oil into the open crevices between the cog body and the freewheel body that screws onto the hub.
