What are air springs?
Air springs, despite their name, function differently from traditional coil springs.
Air springs, or airbag springs, are integral components of your car's air suspension system, powered by an electric air pump or compressor. The suspension system maintains vehicle stability during movement. Meanwhile, air springs act as rubber bags of air, providing space between the chassis and axles.
There are multiple kinds of airbag springs, but most can be classified under these two categories:
Sleeve style: Smaller in diameter and relatively flexible, sleeve-style air springs are designed with lift and ride stabilization in mind. They’re more ideal for tight spaces when the vehicle load will be lighter.
Convoluted/Bellows style: Wider and larger, these tend to have heavier load capacity and are commonly used in trailers, heavy-duty pickup trucks, and tow trucks.
What are the symptoms of bad air springs?
There are a few common symptoms that your air springs needs replacement, such as:
The compressor seems to be running more
Sagging or bouncing as you drive
Dipping or leaning when braking or accelerating
Keep in mind: You might be able to spot an air springs problem just by looking at the car itself. If you’re parked on a flat surface, you might notice one corner of the car dipping lower toward the ground than the other three corners, almost as if you have a flat tire.
What is the life expectancy of air springs?
While airbag springs, or air springs, don’t have a set “life expectancy,” they’re normally fairly durable. However, after around 4-10 years of repeated use, they’ll degrade and require replacement.
Pro tip: Get your airbag springs checked anytime you have a standard car maintenance
check-up. Is replacing air springs yourself easy?
Replacing air springs is best left to those with advanced auto repair skills.
It involves working with suspension components, compressed air, and various tools, which can be complex and potentially dangerous if not done correctly. If you lack experience with complex DIY car projects, it’s advisable to let a certified mechanic diagnose and fix the problem.
