Tank tracks from blender to Unity3d

I have a tank mesh that i have created in blender. When i move the tanks body the tank tracks rotate. How do i keep this functionality on Unity3d?

I exported the mesh as FBX. I imported as an asset to Unity 3d. Now i don’t know how to get the tracks to rotate. I was going to use wheel colliders but obviously the tank tracks are not circular in shape. Can someone show me a video tutorial or show me a tutorial. I would prefer the least amount of coding possible, but if it is necessary, i would prefer Javascript please. Thank you.

Hi NeXtMaN

Blender basically exports mesh in *.obj file and *.obj file can’t contains any animation information so you have to manually write code for apply rotation tracks of tank when your tank moving.
