What Are the Common Issues with Air Suspension on Trucks?


A truck's air suspension system can be very reliable and efficient, providing a smooth ride, increased stability, and improved overall performance. However, if something goes wrong with this system, it can cause major headaches for any truck owner. So, what are some of the most common issues that may arise in this area?

Leaking Airbags

One of the most common issues with an air suspension system is a leak in one or more of the airbags. This is usually caused by damage to the bags themselves, as they are quite exposed to the elements and may be damaged by stones thrown up by passing vehicles. They could be punctured, and this could cause the corner of the vehicle to "droop" in that area. You may also notice that the compressor runs continually as it is trying to pump air into the broken bag. If one of the bags springs a leak, you must replace it as soon as possible to restore functionality.

Faulty Compressor

The compressor is responsible for supplying pressurized air to your truck's airbags. If it malfunctions or fails completely, then your airbags won't receive any pressurized air, and your vehicle won't have any active suspension.

Faulty Pressure Sensors

The pressure sensors are responsible for monitoring and regulating the pressure in each individual airbag. If one or more of these sensors fail, your vehicle might not be able to detect when too much or too little pressure is present in each bag and thus cannot adjust accordingly. This can lead to instability or poor handling when driving. In this case, you'll need to replace all faulty pressure sensors in order to restore the proper operation.

Damaged Lines

Heavy-duty, flexible hoses and lines connect various parts of the system. Sometimes, issues can arise here with the lines themselves or connectors.


A properly functioning air suspension system can provide many benefits, including improved stability and smoother rides when driving off-road or over rough terrain. However, when something goes wrong, it can put a major wrench into your plans and cause major headaches for you as a truck owner. So make sure that you keep an eye out for any potential problems, such as leaks in the bags themselves, faults in the compressor unit or faulty pressure sensors. It is best to schedule regular maintenance visits to a mechanic, so they can monitor these areas for you and try and avoid any problems in advance. However, always address these issues quickly before they become bigger problems.
