RC semi steering knuckle upgrade

This is a steering knuckle for an RC semi. It has been upgraded so that the connections to the tie rod and swivel pins are printed such that the layers aren't separated by screws or by the forces of the tie rod.

I'm not a car person so I might be using some of this terminology incorrectly. Or maybe the car guys will understand this better:

Circle strong. Original bits attach to circle bad. Plastic layers break bad. New bits print outside of circle, have their own strong circles, strong. Place new bits then force bearing circle (extra strong metal circle does spinning good) into circle. Circle and bits together strong.
