Noisy strut rod?

I'm guessing that you lubed the poly bushings where they pass through the K member?
You mention "noise" but not what type of noise. Squeak? Creak? Snap? Pop?
The sound you get by rubbing dry fingers on a rubber balloon is usually related to lubrication. A creak is often metal related where the parts are flexing. Snap can be where tension builds and then something suddenly shifts over, under, in, out, whatever.
You could disconnect one side at a time and see if the problem goes away or have a helper bounce the car while YOU are underneath looking for where the sound comes from.
