SimpleWheeledVehicleMovement \ How to work with it?

Hi. At first I didn’t want to post anything about this but I can not make this work…
I have a mesh with 9 bones ( 8 wheels and 1 body ) and I can not set this up so I can add throttle or steering input.
The mesh is working as it should, I tested it with WheeledVehicleMovementComponent4W when I excluded 4 wheels (bones). Its all well if I treat a mesh with WheeledVehicleMovementComponent4W as if it has 4 wheels.
Animations are set as they are in templates.
Here are some SS and thanks!
