Reply to Vibrations in DJ booth cause unwanted pitch changes (VCI-100 SE), help!

Hey guys,

So lately I've been having a problem where vibrations caused by monitors or the bass from speakers nearby cause slight pitch changes in Traktor. I believe this is due to slight movements from the outer part of the jog wheel.

I have taken the back case off of my VCI and tightened the jog wheel assembly, but it seems this only tightens the inner part of the jog wheel.

Even after tightening, there seems to be play in the jog wheel, it clicks up and down. During once instance, I had to place a folded piece of paper under the jog wheel to keep it from moving slightly.

Any ideas how to fix this?
