When Should Car Undercarriage Be Maintained?

What does a car chassis include? When should I maintain my car’s chassis? Let’s learn about the article below with Caron!

Overview of car chassis

The car chassis is an important part of the vehicle, located under the vehicle body and is significantly responsible for supporting and protecting other vehicle components. A car’s undercarriage is not only a strong structural part, but also contains important systems such as the suspension, braking system and steering system. The stability and safety of the vehicle depends largely on the effective operation of the car’s chassis.

The car chassis is not simply a support component, but is also responsible for carrying the vehicle’s load and absorbing shocks when the vehicle moves on the road. It helps distribute the load from different components of the vehicle to the road surface evenly, ensuring stability and smooth operation.

Structure and function

Car chassis are made up of many different components, designed to meet protection and support requirements. Some main components of a car chassis include:

first. Suspension system

The suspension system is an important part of the car’s chassis, including parts such as springs, shock absorbers and wheel frames. The suspension system’s job is to dampen and absorb shocks and vibrations from bumpy roads, creating smoothness and stability for the journey.

2. Brake system

The car’s undercarriage contains important parts of the braking system such as the brake fluid reservoir, fluid pipes and other parts related to the braking system. The brake system helps the vehicle stop or slow down safely and effectively, ensuring control and avoiding accidents.

3. Drive system

The car’s chassis contains the steering system, including the steering mechanism, steering shaft and other components. The steering system helps the driver control the vehicle’s direction of movement accurately and sensitively. This ensures the vehicle’s safety and maneuverability on the road.

4. Protection and support parts

The car’s underbody also contains protective and supporting parts such as front bumpers, rear bumpers, impact beams and guard panels. These parts are designed to protect other important vehicle components from collision and damage, while enhancing the vehicle’s aesthetics and performance.

Signs of needing car chassis maintenance

Unusual noise and vibration

If you hear strange noises or feel unusual vibrations from the vehicle’s underbody while driving, it could be a sign that there is a problem with the suspension or other components in the vehicle’s underbody. Common problems include springs losing elasticity, damaged shock absorbers, or loose suspension components. Strange squeaking, grinding or banging noises can also indicate damage or imbalance in the suspension system.

Fluid leak

If you see fluid (such as oil, coolant) leaking from under the vehicle, it may indicate a failure or leak in a part of the system. Oil leaks can be a sign of a broken component in the steering system, brake system or transmission system. Leaking coolant can indicate a problem with the engine cooling system.

Change driving position

If you feel the vehicle’s driving position change, such as leaning to one side or being out of balance, there may be a problem with the suspension or steering mechanism. This can cause imbalance and affect vehicle control. To check, if the driving position is not correct, it is necessary to readjust and check the suspension system and steering mechanism.

Difficulty in controlling and driving

If you have difficulty driving, such as a heavy feeling when turning the steering wheel or a feeling of inaccuracy in controlling the direction of the vehicle, there may be a problem with the steering system or components. other related. This may include the steering gear system, steering shaft, bearing or other component. To correct this problem, check and adjust the steering system or related components.

Worn and damaged parts

Check underbody components such as the front bumper, rear bumper, impact beams and rocker panels to see if they are worn or damaged. Wear and damage can reduce protection effectiveness and cause safety problems. Regularly check and replace these parts if necessary.

Should you cover the undercarriage of your car?

What is a car underbody cover?

Cover the car’s underbody

Car underbody coating (also known as anti-rust coating) is the process of applying a layer of protective material to the undercarriage of the car. The purpose of car underbody coating is to protect underbody parts from corrosion, rust and environmental factors such as water, road salt, dirt and road chemicals.

The car underbody coating process usually includes the following steps:

  • Clean the undercarriage: Before applying the coating, the vehicle’s underbody should be washed to remove dirt, grease and other residues. This cleaning helps increase the adhesion and effectiveness of the coating.
  • Use underbody cover material: There are many different types of car underbody coatings that can be used, including rust inhibitors, anti-corrosion agents, water repellents and dirt repellents. Coating materials are often applied by spraying, painting or brushing onto the vehicle’s underbody surface.
  • Wait for the coating material to dry completely: After applying the coating material, let it dry completely before using the vehicle. Drying time may vary depending on the type of coating material and environmental conditions.

What are the effects of car underbody coating?

Covering the car’s underbody is a solution to protect and increase the life of the car’s underbody. Some benefits of car underbody coating include:

  • Anti-corrosion protection: Vehicle underbody coatings can provide a layer of corrosion protection for important components underneath the vehicle. When the vehicle is exposed to the elements such as water, road salt, road chemicals and dirt, an underbody coating will help prevent environmental impact and corrosion, keeping underbody components protected and lasting longer. longevity.
  • Reduce noise and vibration: Vehicle underbody coating provides an anti-vibration and soundproof layer for the underbody of the vehicle. It helps reduce noise and vibrations from the road surface and obstacles, providing a smoother and more comfortable driving experience.
  • Easy to clean and maintain: Undercarriage coating creates a non-stick and anti-fouling layer, making it easy to clean and maintain the underbody. Easier removal of dirt, grime and harmful chemicals helps maintain cleanliness and enhances the performance of underbody components.
  • Increase aesthetics: Undercarriage coating can provide an aesthetic appearance and highlight the underbody of the vehicle. It helps obscure unwanted underbody parts and creates a sporty and professional appearance for the vehicle.
