How Long Does a Suspension Air Bag Last?
Air suspension systems are becoming increasingly popular among truck owners who like to tow items behind their vehicles. These systems are designed to replace a shock/strut/spring configuration with a series of air bags made out of rubber.
There are several reasons why more truck owners are opting for air bag suspension systems. They’re highly customizable, allowing you to adjust them for various ride preferences and terrains. You can also easily adjust the ride height of the vehicle to either raise or lower it, which aids in getting in and out of the vehicle and can also make driving simpler.
In the air bag suspension system, the inflated air bags sit beneath the vehicle, right at the axles where the mechanical springs and shocks/struts would be. Because they’re made of rubber, there is the potential for ongoing wear and tear as well as damage caused by exterior sources, which might make one wonder just how long the system will last.
The lifespan of your air bag suspension system will vary depending on the auto manufacturer. Common estimates indicate an average of 50,000 to 70,000 miles or 10 years before replacement is needed.
These suspension air bags will be put into constant use, regardless of whether you’re driving. The bags remain filled with air while parked to cushion the vehicle. However, eventually the rubber will become brittle, which can make leaks more likely and cause the side of the vehicle supported by the leaking bag to sink.
Signs you need to change your suspension air bag
If you become familiar with the signs indicating air bag wear and tear, it will be easier to determine when you need to replace those air bags. Here are a few of the biggest telltale signs to look for:
- The air pump frequently cycles on and off, which indicates a leak somewhere in the system
- The vehicle is clearly sagging on one side
- The air pump runs nearly constantly while the vehicle is in operation
- The air bags need to be pumped up before you’re able to drive your vehicle
- You can feel a soft, spongy sensation in the suspension while you’re inside the vehicle
- You find it difficult to adjust the ride height properly to the level of your choosing
If you notice any of these issues, it’s important to take action and have the air bag suspension system inspected by a certified mechanic. Even if you have not had the bags in place for an extended time, there is still a possibility that the bags may have developed a leak caused by outside sources.
