Anycubic Chiron Z-axis top bearing support

Anycubic Chiron Z-axis screw rod vibrates during printing specially when there is sudden change in direction. This vibration causes a rattling noise by the Z-axis screw rod. I do not know if the bearing housing was intended to be not holding the Z-axis top bearing to stay in one place but one thing for sure Anycubic3d customer support did confirmed that it should not be like that.

One temporary solution is to raise the Z-axis rod a littler higher that it touch
