Physics Joint Revolute Problem

I have an issue where the 2 physics bodies don’t conncect through a joint. I’m not sure what the issue is. The joint is located within the car class. Thanks for any help!

Edit: link changed to correct one.

you’ve got the name of one of the bodies wrong in the joint command. You call it car, but there is no car physics body, I think you mean frame. Secondly though, you can’t join two kinematic bodies together.
