Really stuck. Bad import of my car from 3ds max, wheeles are well oriented, but car not

I just attached my wheeles to the main car, just as this user did

i followed all his steps, Instead, look! at this picture, the Z axis on my main body (the car body) is facing Up as it should


Here is my configuration

Everything looks fine but, when i import it to Unreal, look what happens when i insert a box collision!

THE RESULT : WHEN I PLAY AS THE CAR AND LAUNCH THE GAME MY CAR WHEELES OVERLAPS THE FLOOR

WHAT IN THE WORLD I JUST DID WRONG???
