Issue with carbon gt AT drive gear

So I was wanting help from the comunity. So basically my the drive gear bearing keeps popping almost half way out when under tension from the belt. Only one of my AT drive gears are doing this I think it's a manufacturer defect because it has happened right when I got it is just didn't think it was an issue. But I'm getting bad wobbles at 19 MPH and when testing the board while it's not touching the ground one wheel doesn't wobble at all and the other ( the one with the issue) is wobbling profusely. I tried lubing it up but it's still doing it and it's coming out more and more. Any ideas for a fix or should I be able to get a warranty claim on it? The pics with the belt on is what it's doing while riding it's coming out like that and the pics with out the belt on is a comparison to how flush the bearing actually is to the drive gear or how it's suppose to be ( repeat pictures)

 

i dont understand why its popping, but if u screw it tight should be no problem
