Since air suspension is one of the larger investments, you can make for your vehicle, maintaining it should be at the top of your to-do list to keep it running for years to come. Unlike lowering springs and coil-overs, air bag suspension has many moving parts that work in unison to raise and lower your vehicle. Today, we will give you a few tips on maintaining your air bag suspension system.
How Do You Maintain Air Bag Suspension?
The good news is that most air bag suspension systems are pretty self-sufficient and require little maintenance. With that being said, there are a few things you will want to check for, and depending on the climate, a few preventative measures can be taken to keep your system in check.
Draining Condensation In Your Air Tank
Like any type of air tank, whether in your car or your shop, you must drain the condensation frequently to prevent moisture buildup. A water trap, or filter, should be installed to prevent any water from getting from your air tank to your manifold. These traps do not prevent condensation in your tank, so the tank should be drained about every two weeks, depending on how often you use your air suspension system.
Use Air Brake Anti-Freeze In Harsh Winter Climates
You will want to pick up some air brake anti-freeze for those driving their vehicles in colder climates where temperatures typically drop below freezing. Using the instructions provided by the anti-freeze manufacturer, you will want to add the recommended amount to your tank to help prevent the condensation from freezing and damaging your air tank or system.
Ensure Your Air Lines Are Secure
Another great tip for checking over your air suspension system is to ensure your air lines are still properly secure to each component. This is an easy check when you have the car on jack stands or a lift, working on other components. If it's been a while since you have been under your car, set aside some time to raise it up and give all of your lines a once over for loose fitting or damaged air lines.
Check Lock Collars If Applicable
If your air shocks are equipped with a lock collar system, check to ensure they are tight and secure. A loose lock collar can cause rattling and damage to your air struts, so while checking your air lines, ensure the lock collars cannot be loosened with your hand.
Quick Once Over On All Components
While the rest of the system does not require much maintenance, taking a few minutes to give the entire kit a check is always a great idea. Look at the air compressor, and check to ensure that it is still securely mounted and all the electrical wires are intact. If you can access the air strut, look over the rubber bladder for any signs of rubbing or wear that could signify future failure. Lastly, check over any ride height or pressure sensors to ensure they are secure and there is no extra play in them.
