A frequently used shortcut is to just give the whole FW a bath in something like ATF to flush wear particles out, and relube pawls and bearings. You'd want to clean the excess off of the outside to keep it from accumulating grime and grit.
IGH Hubs are significantly more serviceable than freewheels.
