This what i have been following to make it work. But i have found that there are to many difficulty’s with this system if i wanna build of it. So i have started to create my own simplified system. Still a lot of thanks for the help.
I would have done this if i had the time, but that’s not the case
There are several issues in the setup. The main one is with the mesh setup. For best performance and setup the bones should end in the middle of the wheel, the center of the rotation, also all should points +x and if you are usign 3dsmax reset rotation and transformation before exporting.
Also remove the “root” bone, the first bone in the tree should be the mainvehicle mesh itself.
Take a look to this guide, under Joints.

There are some ways to make it simple, for example, you can only animate one of the wheels of the pair and then in the animation BP copy the bone transform and rotation to the paired wheel. But yes, it is easier to begin simple and then add more features. Good luck with the implementation!
