At one point, all cars will need a replacement suspension kit, but every vehicle is different. Depending on your driving habits, yours may need one sooner than another car. So how do you know when you need a replacement suspension kit? Here are a few symptoms of a failing air suspension that can help you to determine when you need a replacement suspension kit.

Car Is Sagging

The airbag and coil spring of your car’s air suspension kit supports the vehicle’s weight and help to cushion energy from road bumps when traveling. This helps to produce a smooth and level ride. When they start to wear down or get damaged, they’re no longer supporting the vehicle’s weight, causing it to sink down. A sagging vehicle, even if it’s only riding low in one corner, can have a drastic effect on your car’s overall performance. With that said, it’s best to install a new airbag or spring from a suspension replacement kit as soon as you notice the car start sagging.

Compressor Keeps Running

Failing Air SuspensionThe compressor is an air suspension part that works to ensure that all of the system’s airbags are properly inflated. Once they’ve reached the appropriate air pressure, the compressor should stop. If it continues running, you may need a replacement suspension kit. Usually, this problem is caused by a leak in the airbag. However, a technical malfunction could also be responsible for a compressors’ continuous operation. To find out exactly what’s causing your compressor to keep running, check the condition of your airbag or have a professional do it for you. If there’s a hole, you’ll simply need to change the airbag. If the airbag is fine, replace the compressor with a new air suspension kit.

Vehicle Produces Bumpier Ride

With time, the shock absorbers, springs, and airbags in your suspension system will wear out, preventing them from absorbing road energy as you travel. This causes you to experience a bumpier ride. Once you notice that your vehicle is producing a rougher ride, especially when traveling through bumpy road conditions, take a look at your car’s shock absorbers. If they’re worn out or leaking, replace them right away to restore your vehicle’s smooth performance.

Car Leans or Rolls While Traveling

Rolling when braking, squatting when accelerating, or leaning to the side when cornering are the most common warning signs that you need a replacement suspension kit. Usually, these issues are caused by worn shock absorbers or struts. However, other damaged suspension parts may be to blame. Regardless, as soon as you notice your vehicle rolling, squatting, or leaning while traveling, lift your car and inspect your suspension or have a professional take a look at it. If you see excessively worn suspension parts, then install a replacement suspension kit immediately to prevent additional damage.

So consult this guide and install a replacement suspension kit as soon as these issues occur to minimize vehicle damage and ensure proper performance.
