The Functions of the Car Undercarriage & How to Take Care of Them for Beginners!

Car Undercarriage – Deciding to own a vehicle needs to be accompanied by a broad understanding of its use and maintenance. Without ruling out other aspects, one of the important elements that must be considered is the components of the undercarriage system. You need to have thorough knowledge of how to maintain it, modify it, and check its condition.

This part of the car has a very crucial role, especially in determining balance and control while driving. Even though we hope to always face smooth and flat roads, the reality is not always the case, because we can encounter steep and muddy roads at any time. In situations like this, optimal performance of the car’s undercarriage components will provide significant support for comfort and stability for the driver and passengers.

What are car undercarriages?

The undercarriage system is a series of car elements located at the bottom of the vehicle. These elements have a very vital role in supporting stability and comfort while driving.

The structure of a car’s undercarriage consists of several components, such as suspension, rims, tires, ball joints, bushing arms, bearings, supports, and the like. Each of these components has a different function from one another. Some play a role in maintaining the overall stability of the car, while others are tasked with dampening vibrations that arise due to suspension movements in the car’s undercarriage.

Car Undercarriage Functions

The car’s undercarriage system is a significant component of a vehicle, playing a role in supporting the total load of the vehicle and helping to regulate the movement of the car while on the road. Generally, the undercarriage consists of several parts such as the suspension, braking system, wheels and tires.

Each of these elements has a crucial role in maintaining the safety and comfort of the driver and car passengers. Let’s take a closer look at the functions of this car’s undercarriage system:

Supporting Vehicle Load

The undercarriage system functions to support the entire weight of the vehicle, including the weight of the car itself, the cargo being carried, and the passengers. In this case, the suspension components have a major role in holding the load so that it is not directly transmitted to the wheels, as well as dampening vibrations and shocks that may occur when driving.

Guarantees Vehicle Stability

One of the important functions of the undercarriage system is to ensure vehicle stability. Suspension parts have a very important role in ensuring the car remains stable while traveling on the highway and reduces vibrations that may occur when passing over uneven road surfaces.

Controlling Car Movement

The undercarriage system also has a role in controlling the movement of the vehicle. Elements of the steering system become very crucial in controlling the direction of the car when moving on the road. In addition, the braking system also functions to stop the car quickly when needed.

Overall, the car’s undercarriage system is not just a mechanical component, but is a series of elements that work together to ensure safety, stability and comfort while driving.

How to Find Out if a Car’s Undercarriage is Damaged

Here’s how to detect if there is damage to the legs of the car:

A vibrating sound appears on the component

Usually, a component that is damaged will produce an unusual sound, for example, vibration or buzzing. This buzzing sound usually appears due to a problem with the bearing.

If when turning to the left and the buzzing sound disappears, this may indicate that the bearing on the left side is damaged. Similarly, the same checks need to be made for the other parts. We recommend that you do further checks at the nearest repair shop to identify the cause of the damage.

Instability when the car goes around corners

If when the car is turning, you feel something unusual, such as the feeling of the car being unstable or sliding, this could be an indication of a problematic component in the car’s undercarriage system.

Not only that, apart from instability, the car may also give the sensation of floating, as well as making noise or other disturbances. Therefore, it is recommended to carry out a more in-depth inspection by an experienced technician to identify the problem more accurately.

Abnormal symptoms in the vehicle

If there is a problem on the peer side of the vehicle, identifying it may be a challenge. Even so, this step can still be done. As a rule, signs can be recognized by a rustling sound coming from a peer.

However, in some cases, there are components in the peer that can break without giving any signs beforehand, such as parts per snail. If there is a problem with the peer, this will impact other parts of the car’s undercarriage system.

Shocks in the car’s undercarriage

When the vehicle’s wheels shake, this indicates a problem with the components at the bottom of the car. Usually, the problem lies in the ball joint. As a result, the wheel will feel unstable as usual.

Noisy Bearings

One of the other components of the car’s undercarriage system is called a bearing or bearing. As we have understood, the bearings located in the car’s undercarriage system act as wheel supports.

Its function is very significant when the wheels are moving and also as a balancer when the car is moving on the road.

Is it important to regularly check the condition of these components? Of course, because if there is damage to the bearings, noise will appear in the undercarriage of the car and as a result the car will lose comfort when used.

How to Repair Damaged Car Legs

Below we share tips on how to repair damaged car undercarriages:

Perform Tire Screening

The first step is to rotate the tires on the car. The reason is that this component is closely related to the car’s undercarriage system.

Tire size has a significant impact on the performance of the car’s undercarriage. Larger dimensions will reduce the load on the leg system, but can put more stress on the engine.

Therefore, it is important to ensure proper tire rotation and size according to factory recommendations, in order to maintain optimal reliability of the car’s undercarriage system.

Avoid roads with uneven surfaces

As a body support structure, the car’s undercarriage faces quite a large load. Therefore, it is very important to always be alert when driving.

When facing various types of road surfaces, the foot system will automatically feel the impact of the surface conditions.

If you go over an uneven road, the undercarriage system will experience intense vibrations, so it will bear more of the burden of the car’s weight when moving over the bumpy road surface.
