Configuring and Adjusting Your New Air Suspension on Your Car

What does an air suspension kit offer on installation?

– Better vehicle control

– More efficiency

– Comfort during driving

– Effective versatility

– Less or no shocks

Only real car enthusiasts tend to squeeze every last bit of its performance. We meet those wanderlust guys each day. When you install an air suspension, the work doesn’t end at the instalments only. Only the real geeks understand the issues, especially when they want to have a personalised comfort position.

The idea goes like this-How can I put my Volkswagen’s sub-frame on the ground, making it roar on the road?

In this article, we are talking solely about the technical part of air suspension, so if you’re a pro player in the game, stay. If you’re a new guy or less technical person, the article may be confusing on first read.

With all that is said, let’s dive deep.

Why You Should Not Apply One For All Instalment Setting? 

First, understand that there’s no ideal setting fit-for-all. The idea of picking up the right comfortable standard makes it super personal. Only you can decide what suits your driving the best. If you have spent nights experimenting with your wrench, congratulations, you’re on the right path. 

In this article, we will discuss a few major factors that would personalise your driving, which are: 

  • Spring Pressure
  • Damping Settings
  • Anti-Roll Bars
  • End Links
  • Design of the Suspension

Spring Pressure and Its Impact on Ride Quality: 

Spring Pressure is a special beneficiary only available to the Air Suspension system. Spring pressure allows the vehicle to get the right ride height by increasing the pressure. The air spring gets stiffer with the insertion of air and release of it. 

Having control over the air pressure gives you flexibility to change the ride height as desired. 

The ride height and amount of pressure needed to depend on the suspension design and what kind of vehicle you’re driving. An ideal spring pressure varies from one to the next.

1. Adjusting Air Springs: 

Suppose you have got a vehicle, directly from the garage and so you have decided not to customise the suspension setting, such as Lower Mounts or Spring Perches. 

Though you have checked and customised the vehicle’s height aesthetically and what seems good to you. 

Now the test drive! 

While test-driving the vehicle, you will see the real difference between what you imagined is right and what would be the real deal. 

You feel that the springs are softer. So your car has too much baby roll. You increase the air spring pressure and find the perfect firmness of the suspension. 

When you return to your home, you find your vehicle’s height is increased and has more wheel gap. 

No worries. Note that. That’s your personal four corner air spring pressure. 

When parking or shutting off your car, shorten the suspension to get back to its original state.

Seems your wrench will have a lot of tasks to complete.

2. Damping Settings: 

Damping can be controlled by setting up a shock absorber. Inside the shock absorber system, there is a small orifice whose job is to restrict the flow of fluid during compression and rebound strokes. This restriction gives the desired damping. 

The modern damping control mechanism involves a shock absorber with an orifice valve and a damping adjustment knob. 

The adjustment knob controls the size of the orifice which restricts the hydraulic fluid flow, respectively. The smaller the orifice, the greater restrictions there will be. 

But how does damping work in reality? 

Whenever your vehicle hits a bump on the road, it experiences a shock, the spring will happily continue contracting and expanding, proceeding to release the energy for a long time after the bump. This is an example of underdamped. 

On the other hand, the extreme opposite of an overdamped situation is also not favorable for a vehicle. In that case, the suspension loses its ability to come back to its original position.

3. Anti-Roll Bars:

Anti-roll bars connect the left and right sides of the suspension. It minimises body roll every time you corner your vehicle. 

You, as per your comfort, can adjust the stiffness of the anti-roll bars, which will offer better control & support, especially during sharp turns on the roads. 

A soft setting allows for more flexibility and body roll, which offer a smoother ride. On the other hand, a stiffer setting offers less control to you and offers stability during cornering. 

Anti-roll bars affect the vehicle’s handling and tailor it to your preferences.

4. End Links: 

End Links connect anti-roll bars to the suspension components. The end link length can alter the preload on the anti-roll bars, which affects their efficiency of controlling body roll. 

Shorter end links increase preload and make anti-rolls stiffer whereas longer end links make them softer & flexible.

5. Design of the Suspension: 

The overall design of the suspension you’re using affects the whole idea of the suspension process. It involves air spring types, shock absorbers, and control algorithms which heavily personalise the comfort & control of driving. 

Modern suspension systems also include some advanced features, such as 

  1. Automatic adjustable ride height facility. 
  2. Advanced systems for different driving modes – comfort, eco, sport etc. for different conditions.

Understand the variations of different air suspension components, and you can modify them to get your personalised suspension comfort.

 Conclusion: 

Air suspension systems are subjective to people’s personal choices and the best experience will always be your personalised one, catered only to you.  

But how can you achieve it? 

In this article, we have discussed the air spring adjustment, damping settings, anti-roll bars, end link, and most importantly, design of the suspension system. 

Understanding each one of them and adjusting them to your personal comfort will give you the best experience of driving ever. 

The Most Common Air Suspension Problems and How to Fix Them

Air suspension system drastically improves your vehicle’s ability, control, and performance. The whole mechanics of the suspension system work on air-filled tubes and electronic circuits which control them. This new suspension system is ideal as heavy-duty vehicles and sports cars use it to optimise their performances. However, nonetheless, you will see some very burning problems in the air suspension system. They are very common and in most cases, each owner goes through that one day. See if you’re facing one of these issues or not. Read the article completely and get these.

How to Find Out Whether Your Air Suspension Has Gone Wrong? 

The only work of an air suspension system is to balance the vehicle of its weight and optimize its speed & performance. The very simplest effect you will notice is a sudden drop in the performance of the car. You will also feel discomfort while driving or losing the grip while turning the vehicle at sharp turns. However, here we are listing down some of the most common symptoms of a faulty air suspensions. 

– Uneven ride height 

– Rough handling 

– Hearing extreme noises from the suspension

– Losing balance in sharp turns. 

– Sagging on one side when the load is heavier than usual. 

– Stuck on bumps or potholes. 

– Airbag leakages

Common Air Suspension System Problems and Solutions: 

If you have been noticing such symptoms for quite some time then you should start thinking about repairing your air suspension system. The next step however is to find what’s wrong. The simplest answer would be to go to a mechanic and ask him/her to solve it. But well, whom we are talking to! For passionate car lovers like us, things should be more dramatic. Let’s find some of the most common failure points of air suspension issues and how to solve them. 

Most Common Failure Points of Air Suspension System are as follows

– Air Spring

– AIR Dryer

– Compressor

– Airlines 

1. Air Leakage: 

The most common problem in an air suspension system is leaking airbags. If you know the working model of an air suspension system, you know what we are talking about. The air suspension system uses airbags instead of springs to resist uneven driving & load management. A compressor controlling the air passage fills the airbags whenever needed. 

Sometimes the airbags start leaking or malfunctioning. This causes air to pass by that leakage if there’s only one. The airbags can’t create resistance to uneven roads. In most of the cases, the O-ring gets damaged or might fall as well. 

All you need to do is to check the airbags for any leakages. If they are small in size, you can patch them but if they are large, you would need to replace the airbags. 

2. Defective Air Lines: 

The compressor uses airlines to fill the airbags. The compressor draws air from the environment and compresses air into the bags to make them bouncy. If you’re feeling uneven height & problems while balancing the vehicle, the airlines may have been clogged or broken. 

Broken or clogged airlines will not let the air pass into airbags causing them to lose balance. In most cases, this happens due to overheating in the suspension system. 

While inspecting the air suspension system, look for broken or clogged airlines. Remove them from the system and check the severity of their damage. If needed, replace them. 

3. Loose Electrical Connection: 

Today’s cars have automatic air suspension systems controlled by sensors & electrical wires. These wires connect air suspension components and control them dynamically. These connections become loose with time. There’s a possibility of them breaking down as well. More to it, the electric fuses can go faulty which can cause faults in the Electronic Control Module. 

Check the electric cables carefully. If you find any loose connections, fix them immediately. If they have been broken, you need to replace them. In case of a faulty fuse, the only option left is replacement. 

4. Malfunctioning Ride Height Sensor: 

Smart air suspension system has height sensors to determine the dynamic height of the vehicle from the road. It sends signals to the ECM of the vehicle and starts operating the air suspension functioning. These sensors send signals throughout the drive and the air suspension controls the air accordingly. This is why you drive safely on both kinds of roads, bumpy & smooth. 

When these sensors go faulty, they can send ECM wrong signals. Those inaccurate signals cause inappropriate leveling which further causes discomfort & imbalance. 

First, locate the height sensors in your vehicle. It must be present in the strut assembly. If you see them faulty or worn out, the only way is to replace them.

5. Faulty Air Compressor: 

An air compressor is the heart of an air suspension system. It compresses the air and passes it to airbags. Bouncy airbags make your driving smooth & comfortable. While the compressor is a vital organ of air suspension, the chances of it going faulty or damaged are also very high. It can be worn out with time or by any accident. 

A damaged air compressor doesn’t send air to airbags. As a result, you feel an imbalance during the drive. There are numerous reasons behind the malfunctioning of the air compressor. This is due to several components present in the compressor only. These components are air filters, relief valves, pumps, check valves, relays, etc. 

While checking for the faults, you must check the entire compressor system. If any of its components have worn out, you must replace it without a second thought.

6. Faulty Electronic Control Module: 

The Electronic Control Module is the device that catches the signals of the sensors and acts on them. It electronically operates the compressor and controls the right air pressure. This guides the compressor to create the right pressure inside the airbag. When the ECM starts malfunctioning, the air suspension will also not work properly. 

If you have checked all the other issues mentioned above, the problem can be a faulty ECM. This is a serious issue and needs expertise. So we request you to go to your nearby mechanic and ask him/her to repair it or replace it if needed. 

Conclusion: 

Modern air suspension systems are electronically equipped with sensors, gears, automatic compressors, etc. Air suspension kits are great for improving your vehicle’s performance instantly. However, there are several very common faults you may see over time. In this article, we have covered the most common problems in air suspension systems and how to solve them. If you’re facing issues in driving your vehicle, you should check for your air suspension malfunctioning as we mentioned above.
