Sc2 Pro - broken bearing?

After just two months of life I have this problem. Suddenly I felt some weird knocks in the spikes of the force feedback on kerbs or rebounds. I thought it was a software problem but then I found that the center column moves. I checked the 4 bolts under the QR and they are all fully tight. Could it be a broken bearing?
Thanks

Please make a support ticket to our system. It might very well be a bearing issue.

Thanks for your reply Mika.
My reseller DGS create this morning a ticket on your support system. We are waiting for the answer.

Mika the unit have only two months, I hope a replacement instead of a repair… you think Is possible?
Can you tell me more or less how long will take to solve the problem (I’m located in Italy close to Rome )?
