Animating a rotating component in Showcase

[Anonymous]

Am working on a car project designed with Inventor Professional, I desire to have the car move in a shocase animation. So I get to apply a constraint to drive the chasis of the car. I also apply motion constraints ( translation/rotation) between the chasis and each tire of the car.
This worked very well in Inventor as the car moved while the wheels spinned too.

Imported to showcase, I drive the behavior but the wheels are wobbling and more annoying is that the rotation is far away from their axes of rotation.

Please, I need help to fix this. It's actually a Final Project in School.
Thanks.

Can you attach the assembly and parts?

To use the behavior from Inventor constraint, the constraints need to be at the first level of the assembly.
