Hi everyone,
This is my first pinball so sorry if I'm asking obvious things.
I have the left flipper of my Stern RBION making some noise. Here's a video describing my issue:

If I move the flipper a little bit the noise disappear.
It moves a little bit when inactive (look at this second video), I don't know if that's normal:

I've replaced the coil sleeve and the spring and cleaned everything, but it didn't solve the issue. The flipper is working great, but there is this annoying noise.
Right flipper is working correctly:

Could you help me to solve this issue?
Thanks!
