What is a Car Knuckle Arm? Its Function and How It Works
Talking about the components found in the car suspension system is very diverse. However, one of the components of the suspension system that you need to know how it works and its function is the knuckle arm. Let's learn more about this component by paying attention to the following review.
What is a Knuckle Arm?
Although it is often heard, there are still many who do not understand what a knuckle arm is? This component is part of the car suspension system or shock absorber system when the car passes over damaged roads.
Function of the Knuckle Arm
The knuckle arm itself has several important functions in the successful performance of the car suspension system. Here are the complete functions.
1. Facilitates the front wheels of the car to move and rotate when the car turns
The first function of the knuckle arm is to allow the front wheels of the car to rotate and move when the car is turning. As is known, the knuckle arm is usually installed at the lower or upper end of the front wheel spindle. This component is also connected to the car's steering system, the front wheels of the car, and the car suspension system. So when the driver turns the steering wheel to turn, the knuckle arm will automatically move according to the direction of the steering wheel.
2. Load support for the car
The second function of the knuckle arm is as a load support for the car. As previously explained, the position of the knuckle arm is located at the front wheel. This makes this component capable of supporting the weight of the car so that the car can move safely and stably on the wheels.
3. Provides a point for brake installation
The knuckle arm also functions as a provider of a point for brake installation. This way, the driver can easily stop or slow down the vehicle.
4. Maintains vehicle stability during maneuvers
This component also functions to maintain vehicle stability during maneuvers. The position of the knuckle arm, which is directly connected to the front wheels of the car, makes the car easy to maneuver when controlling the speed of the car or turning. This is certainly very much needed when the car is maneuvering.

How the Knuckle Arm Works
For the knuckle arm to perform as expected, it works together with other components of the suspension and steering systems of the car. The way the knuckle arm works is not complicated because this component directly affects the performance of the car's suspension system. The knuckle arm supports the performance of other components because this component serves as a seat for the components.
When you want to turn, the rotational force from the steering will be transmitted to the lower arm, upper arm, knuckle arm, and then to the ball joint. The transmitted rotational force makes the knuckle arm easily move and steer the front wheels of the car according to the turning angle given by the ball joint.
When you pass over a damaged road, the knuckle arm works together with other suspension system components such as springs and shock absorbers to dampen vibrations from the car's wheels.
Considering the function of the knuckle arm as a supporter of the suspension and steering system functions of the car, you need to pay attention to the condition of this component. If this component is damaged, immediately take your car to the nearest Daihatsu workshop. Because if not handled by a professional, it can endanger the safety of the driver and passengers.
A damaged knuckle arm can make the car difficult to control when turning, the car's wheels cannot support the weight of the car, and the car's speed becomes unstable. To prevent this from happening, let's check the condition of your knuckle arm right now.
