I was complaining to my shop recently of the same thing and they suggested some sort of plate that sets between the spring and the housing to allow the spring to compress/decompress & rotate with less noise. I'll look for the paperwork they gave me tonight and include it in this post. I haven't tried it, but think it would likely help... a bit.
