THIS is a steering knuckle:

The factory even clearly defines it.

The red arrows point to the knuckle. The yellow arrow points to the spindle which is part of the knuckle.

The term "dropped spindle" referred to the actual spindle being placed up higher on the knuckle (Closer to the upper ball joint) to effectively lower the vehicle, all else being equal.
