I may be wrong but the axle grease is likely coming from t he seal where the hub slides over the axle tube. It then spreads and finds the seams such as where the brake drum slides over the hub. It appears the whole outside of the inner hub that would normally be covered by the the brake drum is wet. If that is the case you should remove hub assembly and replace inner seal.
