I made a car but it doesn't work

I created a car in blender. And i exported in fbx file but as you see in video, car bounce by it self.

can someone help me?

this is video link:

and this is fbx file:

thank you for helping me.

Really want to help on this one -
It’s not the animations because it happens without them.
It’s not anything taking place in the bp itself because it happens if it is entirely emptied.
I made about 8 similar test cars to try to figure out the source of the problem - all of them cause the same result.

It acts like it is constantly trying to bounce out of a collision, but is being tethered bac and never actually leaving the collided state.

If that is what is actually happening they really need to rework it so that the Example can be used as one.
I hope someone can provide an answer.

Remove the bones and re-import the mesh. Make sure to set the origin of the wheel to the center.
You do not need bones for unreal 4. So long as you parent all the wheels to the car u should be fine
