Make the wheels of a truck trailer have the ability to turn !

Hi to all,

I’m quite new to unreal and not yet a script wizzard :wink:

I’m facing a hard time to find a solution to my problem and would please need help.
The situation is simple : I have a truck and a trailer , the truck wheels works fine , but not the trailer wheels, as i would like this trailer wheels to turn to when steering. It is a huge trailer to carry wind blaid, so the back steering wheels are needed.
Does anybody have already faced this problem?
Help : it’s getting me crazy

Thanks for any help
