In automotive suspension, the steering knuckle is a part that contains a wheel or spindle hub, and attaches to the suspension and steering components. It's also called steering wheel, spindle, upright or hub, too.
Wheel and tire assemblies are attached to the hub or spindle of the knuckle in which the tire/wheel rotates when held in a stable motion plane by a knuckle/suspension assembly.
In the accompanying photo of a double wishbone suspension, the knuckles are displayed attached to the upper control arm at the top and the lower control arm at the bottom. The wheel assembly is shown attached to the knuckle at its center. Notice the protruding knuckle arm, which is pinned by a steering mechanism to rotate the finger and wheel assemblies.

Steering knuckles come in different shapes and sizes. Their designs are different to suit all types of applications and suspension types. However, they can be divided into two main types. One is equipped with hub and the other is equipped with spindle.

In a non-drive suspension, as shown in the first photo, the knuckle usually has a spindle to which the drum brake or rotor brake is attached. (In this figure, the central spindle is not visible to the wheel assembly wheel.) The wheel assembly/tire then attaches to the available lug buttons, and the entire assembly rotates freely on the shaft axle.
In the drive suspension, the knuckles do not have spindles, but have hubs affixed to the bearings and shafts of the drive mechanism. The tip of the propulsion mechanism will then have the mounting studs necessary for wheel/tire and/or brake assemblies. Therefore, the wheel assembly will rotate when the drive shaft (or half-axle) determines. It will not change by itself, but only if the shaft is released from the transaxle or the differential.
The actuated suspension as described may also be piloted. This is often called the drive/steer setting.
