I can totally understand you. It’s frustrating to have such a problem. And it’s even more frustrating when people like me keep on telling that everything is ok while it isn’t. I really hope this will come to a good end. And merry Christmas to you!
Old message but have you checked the QR pieces are tightened too. In the beginning I had one loose screw/bolt on the wheel side QR and the symptoms were like yours. I tried them by hand and did not notice, but the wheel rattled when driving. I had to open it again, tighten the bolts and it was fine after that.
Yes, I have checked and retightened multiple times. It also makes the sound if I disconnect my wheel and grab hold of wheel side QR. => I have removed and retightened those bolts as well with same results.
Now I’m basically waiting on the RMA process from Simucube to get going, holidays are getting in between a bit.
Since I have similar noise, can you share with us what happened with your claim? Did they found some malfunction?
