1.What is Steering Knuckle in a Car?
You must have heard about it, perhaps even had to replace in your vehicle, or sold it in your auto parts shop. But what is a steering knuckle and what does it do?
Let’s begin by defining the component.

2. Why are steering knuckles important in a car?
A. They are safety parts. They hold the wheels in place while allowing them to move vertically as well as turn to follow driver inputs.
If the knuckles malfunction, a driver loses control of the vehicle. In most cases, driving comfort is affected besides the safety concern.

3.What is the difference between a steering knuckle and spindle?
The spindle usually attaches to the knuckle and provides the surface to mount the wheel bearing and hub.
Non-drive wheels or suspension come with spindles while driven wheels do not. Some driven knuckles feature a spindle, though, which is usually hollow and splined.
The hollow spindle allows the CV shaft through.
