Common air suspension problems may seem miniscule, but they’re actually one of the leading causes of suspension failure. Fortunately, there are ways to avoid these issues. The best way is to keep an eye out for the warning signs discussed below so you know when it’s time to repair the system.
Air Spring Leaks
One of the most common air suspension problems is a leaking air spring. With time, the rubber components of these parts will deteriorate, creating holes and tears and causing an air leak.
There are various warning signs that your air suspension is suffering from an air leak. For example, you may experience a bumpier ride because a damaged air spring can’t absorb the shock from bumps in the road. So all of that movement flows through the suspension system without any cushion.
You may also notice that the air compressor is constantly running. The air compressor works to keeps the bags and springs properly inflated. When there’s a leak, the compressor will keep running.
On top of that, if there’s a leak in the air springs, the height of the vehicle will drop or it will sag on the side where the damaged air spring is.
Faulty Air Compressor
A faulty compressor is also a common air suspension problem. As stated previously, the compressor works to keep the air springs inflated. Oftentimes, a compressor malfunctions because it’s overworked, meaning that it runs more often than usual. This wears it out and causes the part to fail faster.
One way to determine if your air compressor is faulty is to check the vehicle height. If it’s riding lower than usual, the compressor may not be working properly or at all.
Hearing noises coming from the part also means compressor issues. Clinking, grinding, or whining indicates a problem with the motor or fan.
Excessive Moisture in the System
The compressed air within an air suspension system contains moisture that can accumulate and lead to severe damage. This issue is caused by a malfunctioning air dryer assembly, a part designed to remove moisture from the compressed air. Excessive moisture in the suspension system could result in rust and corrosion.
Checking the suspension system for physical damage like rust is the easiest way to determine if there’s too much moisture in the compressed air. This problem can also affect leveling capabilities, the compressor, or overall suspension performance, so you want to check the stance and performance of your vehicle as well. If it’s riding lower or sagging or if you’re experiencing a bumpier ride, it could be because there’s too much moisture in the system.
How to Fix Air Suspension Issues
The quickest and easiest way to fix these common air suspension problems is to have the system repaired or parts replaced as soon as you notice any of the issues above. This helps to prevent complete system failure.
You may also want to consider converting your air suspension to a coil spring suspension. These are designed to produce an equally smooth performance without having to deal with the problems listed above.
Understanding common air suspension problems is the first step to preventing system failure, so take the time to get to know the issues and schedule a suspension repair as soon as they start happening.
