Crazy animation / physics

Unreal (4.18) and Maya (2018) are driving me crazy right now. I’ve been trying for days to import a car from Maya to UE4 in order to have it animated in my game, but I somehow end up with the wheels twisting the car body as seen below.



Any help will be much appreciated as I’m running out of time for this project.

I included the UE and Maya projects.
