steering wheel shaking (g29)

I have a problem with my logitech g29 steering wheel, the steering wheel keeps shaking and i feel it when i'm trying to hold it steady, this is very anoying since that because of this i can't get very high speeds because the shaking slows the car down, and i can't make proper turns. Even when i'm holding it is going left and right the whole time, anyone know if this is a bug from the game or if there is something wrong with my wheel, i bought the wheel previous month. I filmed it and uploaded it to youtube: https://youtu.be/AuO0g8kUH40
