Wheel Colliders rotate when adding colliders (Unity 5)

I’m trying to setup a car. So first, I add a rigidbody to the parent, then added empty gameobjects with wheelcolliders.41286-1.png

Now, when I try to add a collider (using a mesh collider and box collider), the wheel colliders rotate.41287-2.png

When I add more colliders, the wheel colliders get more rotated.
Then, when I remove the colliders, the wheel colliders stay at the same rotation as when there were other colliders.

I tried adding the box and mesh colliders first then the wheel colliders and this still happens. I also tried removing the wheel colliders then re-adding them still the rotation is there. I haven’t added any scripts to the project yet.

I did this in Unity 4.6 and this doesn’t happen. Am I doing something wrong or is this a problem with Unity 5? (Unity 5 RC2). Thanks in advance.

sometimes when you add things as children it assumes the positions, rotation, and scale of its parent and has weird results. but from looking at what you are doing it seems to make sense. actual i seen some other posts like this…maybe cause version 5. im still 4.6. anyways, did you try looking at the actual component settings in the inspector under the gameobject? i would think that resetting your center and size might be a fix for you.

Same issure here.

Wheel Colliders in Unity 5 acts very strange. They’re rotating on their will even that their rotation in the inspector is shown as 0,0,0.

Also there is a lot more of unpredictable behaviours with wheels, like the vehicle that falls from 1m, bounces and goes into space. You can find more examples of a broken behaviours in a videos like this:

Will this things be fixed soon? Because right now the Wheel Collider is fully broken.
And what about documentation, when it will be updated with proper tutorials on how to use the new friction curve parameters, etc?
