In general, you should inspect your air suspension every 12,000 miles. Signs that your shocks may need attention include:
·         Diving during heavy braking
·         Wandering on the highway
·         Hitting bumps hard
·         Air leaking

Struts are wear items that absorb countless bumps in the road, which is why replacing struts on a car is recommended every 50,000 miles.

Air Suspension vs standard/spring suspension

Aug 14, 2018
suspension system is always integral to a vehicle drives. Metal spring is the most widely used suspension systems in vehicles. Shock absorbers and coil springs function to maintain wheel oscillation, vibration and bounce, compensate for road surface irregularities and support added weight without excessive sagging.

For comfort and safe driving and riding experience, the improved technology has been used with advanced electronics to make suspension system handy, fast, precise and load bearing in modern vehicles. Air suspension systems have long been used in heavy loaded vehicles, like trucks and buses. It has become more and more popular over the last decade to replace metal springs offering more control and load capacities than traditional springs. If you are looking for a new car or used luxury car, you will likely see air suspension on the standard or optional features.
 

How Air Suspension System Work

Instead of steel or leaf springs, an air suspension systems typically consists of air spring, also known as plastic/air bags, tough rubber, and an airline system, connected to an on-board air compressor, valves, solenoids, and under electronic controls. The on board compressor is an electric pump, used to feed air to the air bags via multiple lines. Valves play a important role in air direction control, allowing air to enter different parts of the system. In electronic systems, when the system adjusts for different driving conditions, solenoids inflate and vent the airbags by opening and closing to change the amount of air entering each airbag. An electronic control module controls the on/off switches, monitors pressure and manages ride height. Air springs are flexible and have certain amount of elasticity. The more they are compressed, the increased stiffness will be produced.

Air springs can provide adjustable suspension and load support by adding air when riding loaded, and deflating air when riding unloaded. They allow your vehicle to sit very low to improve its street credibility, and rise to a level high enough to handle inconsistencies and obstacles on the road. Air springs are the only adjustable load support product, offering vary load and leveling capacity as well as improved ride comfort.

Pros and Cons of Air Suspension

The Benefits

Today's air suspension systems possess three major advantages over metal, conventional springs:
  • Near instant tuning: Air suspensions provide a wide range of spring rate and load capacity. In-car adjustability can get the ride load, height and rate tuning in a few minutes.
  • Ability to adapt handling to different situations: vary spring rate combined with the performance customization provide your vehicle enormous potentiality in performance, enabling real time tuning and a cushy ride with increased comfort on a rough road.
  • Towing capabilities: the system makes it easier for trucks and similar large vehicles to handle heavy load. Drivers can increase stiffness when towing large loads while improving ride comfort. Some today’s SUVs have air suspension feature for better handling under variable load conditions.

Air Suspension Drawbacks

  • Leaking is an usual vulnerability shared by all air suspensions. A system will go flat when it cannot hold air any longer. Leaky or clogged air lines and leaking air springs are the common air ride problems.
  • More cost in buying and maintenance: it is an option at an extra cost when buying a car in the first place. Usually, luxury cars, high-end cars and some SUVs provide air suspension as standard feature. The maintenance costs can be higher than standard coil and shocks. Many drivers replace worn systems with traditional suspensions for cost consideration. However, still got many driver choose air suspension for safety and quality reason.
  • Installation: it will take more time to install an air suspension due to the complexity of wiring, lines and hose installations, and installation requires the use of various tools. So hiring a professional mechanic to do it is the best option to guarantee the safety and vehicle integrity.
If you are torn between a car with and without an air suspension system, the above information is hopefully helpful for you to make the decision. Any system will wear and break as it ages, so leaving some room in your budget for maintenance and repair is another consideration you many need as well. So an air suspension can boost your ride quality, improve towing capacity and customize performance of your vehicle.

The various parts and systems that make cars run optimally require consistent care and attention in order to function well. Even though we may attend to our vehicle regularly, things can still go wrong. There are many reasons why car parts fail or begin to malfunction, and many of those reasons may be out of our control. However, if you can’t control all of the issues that your car may encounter, then it might be worthwhile to know a little bit about detecting symptoms of failure of the various parts in your car. Whether it be the exhaust, the oil system, or the transmission, different symptoms can tell you where to begin when dealing with part failure.

One of the systems that is especially important to pay attention to in a car is the suspension. Suspensions in various cars and models look different depending on the manufacturer, the year it was built, and the performance standards associated with the brand. For instance, the suspension on a four-wheel-drive off-road vehicle will look and act very differently from that of a luxury sedan. Air suspension is a relatively new development in the auto industry that relies on specialized air bags and an air compressor for optimal functioning. If you own or drive a car with an air suspension, it’s important to be aware of the various issues that are unique to an air suspension and how to deal with them. If your air suspension fails, it can have serious, lasting effects on your vehicle, not to mention short-term significantly reduced reliability and performance. Here is a bit more information about air suspension systems and how to detect and deal with the common issues they experience.

WHAT DOES AN AIR SUSPENSION DO?
Air suspension is an alternative to typical suspension in a wide variety of vehicles on the road today. Air suspensions serve the same general purpose as other types of suspension: they are designed to support the vehicle and shield it from the imperfections in the road. Furthermore, it aids the car in turning and staying stabilized on uneven terrain. The air bags in the suspension fill with air via an air compressor rather than relying on fluid-filled shocks and springs for support as you may seen in a normal suspension.
 
COMMON ISSUES ASSOCIATED WITH AIR SUSPENSION
The issues that air suspension typically encounters are unique to the parts that are associated with such a design. Not all cars have air suspensions, and it’s important to know what type of suspension your car has so you can recognize the signs of failure. Here are some of the common issues associated with air suspensions in particular:

LEAKING AIR

Since air suspensions run off of air, it is relatively typical for air leaks to occur when there’s an issue. The various parts of the suspension offer different avenues for air to escape, which include the rubber seals that are susceptible to holes and punctures. Since there are several components of your air suspension that can be the culprit of leaking air, it’s essential to consult with a professional automotive technician who is familiar with the various parts involved in air suspension—especially with your specific brand of car.

COMPRESSOR MALFUNCTIONING

As we mentioned before, the air bags that support the car are filled with air by way of an air compressor. If the air compressor begins to fail or malfunction, then the bags won’t fill with air, allowing the car to slam down onto other critical parts on impact. The compressor relies on a motor to generate air to fill the bags with, and this is generally where issues come up. If the compressor is beginning to fail in your air suspension, you might encounter strange noises related to the compressor motor dying. You might also experience the vehicle sitting lower than it normally does on any given day. These signs are concerning, and should be addressed immediately
 

WHY AN INITIALLY ACCURATE DIAGNOSIS IS CRITICAL TO AIR SUSPENSION REPAIR

Proper air suspension repair begins with an accurate diagnosis. Because air suspension problems can arise due to a number of issues with the suspension system, it’s important that your trusted automotive shop performs a diagnosis which isolates the problem accurately. Additionally, after the problem has been diagnosed properly, the repair protocol for that specific vehicle should be followed. Whether the problem arises from the compressor or a damaged seal somewhere, suspension parts must be inspected with attention to detail to avoid overlooking the actual problem and prevent unnecessary, expensive repair work. The experts here at Kueen Sing Auto have served clients from all over Malaysia.
