What is the purpose of the steering knuckle?
There’s one steering knuckle attached to each front wheel, and its purpose is to turn your wheel when you steer. The top and bottom arms of the steering knuckle attach to the suspension system via pivots called “ball joints”.
Is the wheel hub the same as the steering knuckle?

Where does the steering knuckle go on a MacPherson strut?
The steering knuckle provides a mounting point for the wheel hub. Found behind each front wheel, the knuckle makes sure its associated wheel moves within a certain plane. In a MacPherson strut-style front suspension, the top of each knuckle bolts to a strut assembly. The bottom of the knuckle attaches to a ball joint in the lower control arm.
What are the symptoms of a bad steering knuckle?

Tie rod ends connect to the steering knuckles, which directly control the wheels [source: Burt].
