Is a steering knuckle and spindle the same thing?
The terms spindle and hub are sometimes used interchangeably with steering knuckle, but refer to different parts. The wheel and tire assembly attach to the hub or spindle of the knuckle where the tire/wheel rotates while being held in a stable plane of motion by the knuckle/suspension assembly.
What does a steering knuckle connect to?
Steering & Suspension On cars with conventional suspension systems, the steering knuckle includes a spindle and connects the upper and lower ball joints. On cars with MacPherson strut suspension systems, the steering knuckle connects the strut assembly to the lower ball joint.
How can I tell if I have a steering knuckle?
Performing an inspection of your steering and suspension system will help you determine if this is where the problem is. If you look behind the front right or left wheel of your vehicle, you’ll find the wheel attached to a steering knuckle. Each steering knuckle links to the steering and suspension systems.

Turning the Wheels: Wheels transmit the least force from hitting an obstacle when they are rolling straight ahead. As soon as the wheels are turned, extra force is transmitted to the knuckle. High speeds while turning multiply that force.

If the car is sliding at all, the force applied to the knuckle is increased again. Bottoming the Suspension: If your suspension bottoms out, the springs and shocks are no longer absorbing any impact.
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.
