B & C Pillar cover removal

[mattpdx]

Does anyone know how to remove these covers? I have a buzzing sound coming from them that the dealer somehow can't reproduce. I have a roll of the felt tape that I want to wrap the backs of the covers. Any help appreciated. It's a 2011 3.5i.

I have a similar buzzing sound. I can replicate it by listening to talk radio or acoustical music. The buzzing sound is a resonance coming from the pillar. It's like having a buzz speaker in my left ear. Need to take it into the dealer to have it fizzed.
