Can't bind to bone in a wheeled vehicle

I have made a model from scratch in Maya 3 times now, add a bone.

in my vehicle blueprint under VehicleMovement, i set wheel 1-4 to the bones, and for some reason no matter what i try it wont bind to that bone.

i tried making a socket on the bone and attaching the wheeled vehicle setup to the bone still no luck…

anyone have this issue before? im so lost… i have a different vehicle that i used in the past and it worked. i imported it into a new
project, same issue can’t bind to the bone… is this a bug or am i crazy?

bump :(, anyone?
