Import static mesh as skeletal not building correct hierarchy

I am trying to import a tank, without bones, into unreal and have unreal generate the bone structure automatically. My tank hierarchy consists of a root hull and then all the wheels are direct children of the hull.

It gets the bone positions right on one side of the tank but stretches the wheels vertically and places the other wheels’ bones at the same location as the first side.

Here is a picture:

I’ve figured it out. The origins of each wheel were set to the corner of the vehicle. Moving the origin to the geometry in blender fixed it. I still have not fixed the scale problem, though.
