Car Trembles a Little After Upgrading Unity (Wheel Collider problem)

Hello!

I upgraded from an older version of Unity 5 to the newest one, and now my car trembles a little when it is accelerating.

The picture on the left is my current wheelcollider and the right picture is a newly created wheel collider. Comparing those, am I missing something that is causing the issue?

  • Ignore radius.

Thanks a lot in advance!

The wheelcolliders for the rear wheels were a little lower than the front wheelcolliders.

Making them the same y-pos solved the issue.
