Camaro -98 rear axle

Hi,
I'm repairing -98 Camaro, which has been in accident. Right rear axle tube has came out few millimeters from 'banjo' and rotated few degrees.
Are these axle tubes welded to 'banjo' or are they just pressed there? I tried to look but can't see any welding joints there..?
Is there any way to press it back or should I replace rear axle?
When I drive this car, it runs good, no noise from rear end...

Thanks,
