E55 front end knock/ clunk (Bc coils)

You guys may have come across my other thread about the insane squeaking coming from my bc coils. Well now I have a knock or clunk coming from front end. It may or may not be related to the coils. It is very loud (like something is shifting or about to fall apart) going slow and over bumps. Sometimes you can also hear it when stopped just by turning the wheel or braking from a slow roll. Here is the kicker, it is intermittent and can go away completely on its own like when I take it in to the shop to find out where it is coming from. The tech who looked for it said he heard no noise and could not find anything apparent under the car. I paid the $40 for a worthless diagnoses and 10 mins into my drive home the noise is back. I originally thought it may me a loose strut but cannot find anything loose. What should I look at, where could this be coming from?

Thanks guys

Hulk that was the first thing I checked as well as the three nuts for the top plate. They are all tight.

You put it on the lift and tried to move it from the rotor like the vid?
