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

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. 

Go universal, if you can?

Universal air ride suspension uses a less complicated manufacturing process but requires slightly more work when it comes to install.  If you are considering a Universal Air Ride Suspension Kit keep in mind you might need to do some modifications just to get it installed in your vehicle or to fit your specific application.  Many Hot Rod or Later model vehicle owners and fabricators will prefer this type of system over others due to the cost savings and OEM fitment.  Most universal kits include a completely separate shock and suspension system meaning the shock is not built into or connected in any way to the bag (example would be an air strut). Instead universal systems will adapt easily to late model axles or coil spring cups.  This way the fabricator can use pre-existing hardware to get the installation done.   Coil spring cups will make an easy adaption from your OEM coils springs and allow the installer to mount the new air spring in place, keep in mind that most of the modifications done to a vehicle with a universal air suspension kit cannot be undone without having to hack away at your old modifications.

Some of the newer late models will also work with these universal air kits, as the design is still the same on many vehicles today.  For instance some of the truck line of vehicles, Chevy, Dodge, Ford models still use this coil spring and axle brackets..

These kits are a great way to save cash and get a quality installation assuming your welder is up to par!  LOL

 

Thinking of buying an Air Ride Kit and need more information?

Air suspension utilizes a large inventory of parts to bring you a complete setup that will allow the driver to adjust ride height, or boost the carrying capacity of your car truck or SUV, all while giving you the best feeling ride on the road today!

This amazing comfortable, adjustable ride is contributed to the air equipment at the wheels.  Have you ever looked to see what your vehicle is riding on?  Well let me explain…

Al vehicles have different specifications at the wheel (i.e.: struts, leaf springs, coil springs, torsion bars and so on..  The type of kit you buy will greatly depend on the hardware that was installed from the factory.  As a good rule of thumb older vehicles are either leaf or coil springs as were newer vehicles are torsion bars, or struts.  It is always best to check before hand, and get a good grasp on what your dealing with.

Many companies will have specific kits built to suit the needs of your specific vehicle, this will remove any equations that might come up upon installation…  For example if a customer builds there own kit for a hot rod or car that has four corner coil spring suspension,  and is overly heavy, he would want to go with larger bags if clearance allows.  This will bring the efficiency of the air kit up as larger bags are easier to fill up then small bags.  Think of it as a Fairly Large Hillbilly compared to a Skinny Joe.  Skinny Joe no matter what you give him is just not going to do the job as good as the Fairly Large Hillbilly.  But again it might be necessary to go with the smaller bag due to the clearance, and remember “NO RUBBING ALLOWED!!”.

The heart of the air ride system is the air supply, and this depends on what you want to do with your vehicle when your done.  Individuals who are looking to play allot and want air on demand, will require a larger tank, compressor, or lines.  where as someone who is just going to do load assist and balancing would only need to maintain a certain pressure at the wheels and could use a single smaller compressor and 1 to 3 gal tank.

No matter what your doing there is a good and bad way to do it, and if there is any question… ASK BEFORE YOU CUT!

 

I have now added some more information to this getting to know air suspension section: 

For folks who are getting started, and needing the basiscs.

Installation of air ride equipment on a vehicle is a challenging yet knowledgeable venture!  There are a few things to consider along the way and hopefully someone finds a few answers there looking for here.

Choosing the right air ride for your vehicle:

Choosing your air ride equipment is one of the most important parts of the venture!  A few things you will want to think about are, installation time, cost of installation, and do you or does your installer have the tools necessary to install this kit.  You will also want to consider custom heights or of you have larger rims additional hardware to correct camber.  These are all things that the company that you are thinking of purchasing from should be able to provide information to you about.  Also depending on how low you want to go, you could end up modifying your wheel wells, cutting your frame and so on, so ask a lot of questions this will save you plenty of frustration down the line.

A few different styles of suspension (If you check your current setup you will see one of these):

  • Struts
  •  Leaf Springs
  • Coil Springs
  •  Torsion Bars.

Plug & Play or Not Plug & Play:

Many air suspension kits in today’s market come in a variety of flavors for each individual vehicle, this allows the customer options when it comes to installation time and required knowledge of installation.  Many companies offer complete bolt on kits that will allow the common auto mechanic to complete the task quickly.  Other options are fabricator kits which can require a lot of welding and over the top modifications and everything in between.  The type of suspension your vehicle currently rides on is a huge factor when it comes to your final purchase.

Installation Requirements:

Depending on the kit you purchased, some installation time can be cut down.  An example of this would be a Plug and Play kit that is Pre-Built, and comes with 100% bolt on parts where no modification is required.  These kits are usually more expensive and payoff quickly by cutting your install time in half!  Most complete air ride kits can be installed over a weekend, with a few friends helping you out.  Just keep in mind that some extreme cases which depend mainly on the current vehicle suspension and aftermarket equipment can result in serious modification and time.  Hopefully you thought about this before you purchased so you know exactly what you’re getting into.

The Finished Product:

The payoff for a custom system like this is amazing. Along with an excellent ride, and auto leveling capabilities, you are even able to adjust the overall feel and ride height of your entire vehicle.  For the common Jo this might not sound like much but in all reality you are taking your car or truck to a huge next level!
