Knocking sound from Drum Brakes 2004 Pontiac Sunfire?

i have a knocking sound after changing rear brake shoes and brake drum. Noise comes from rear driver side when braking. Sound is noticeable when coming to a stop or at low speeds when braking and sometimes notice able when coming off interstate speeds. all components are still in working order, strong. ordered new brake drum for driver side in case the driver side rear brake drum is just not rounded well. Brakes still perform well. Smooth. had a small amount of antisieze lubrication getting on brake shoes when reassembling first time took everything back apart, supercleaned yay!, and adjusted as best i can.. lug nut torque: for past week and half 85- 90lbs and now tonight 100 pounds(as specified by repair manual). Wagner Thermoquiet brake shoes and Wagner Brake drum. Pontiac Sunfire 2004 any ideas? i've been looking all over and i can't find anything constant from any forum.. the sound that is make sounds like when you knock your wood desk you are at right now with your knuckle.
