How often do you need to replace air suspension?
The frequency of replacing air suspension components can vary depending on several factors, but generally, it's recommended to inspect and maintain the system regularly to ensure optimal performance and safety.
Understanding Air Suspension
Air suspension systems use air springs, also known as air bags, instead of traditional coil springs to provide a smooth and comfortable ride. These systems are commonly found in luxury vehicles, SUVs, and commercial trucks. Unlike coil springs, air suspension components can wear out over time, requiring periodic replacement.
Factors Affecting Air Suspension Lifespan
The lifespan of air suspension components can be influenced by several factors, including:
- Vehicle Usage: Vehicles that are heavily loaded, towed, or driven off-road may experience more wear and tear on the air suspension system, requiring more frequent maintenance and replacement.
- Environmental Conditions: Exposure to harsh weather, such as extreme temperatures, moisture, or road salt, can accelerate the deterioration of air suspension components.
- Maintenance History: Regular inspections, timely repairs, and proper maintenance can help extend the lifespan of air suspension components.
Generally, it's recommended to have the air suspension system inspected by a qualified mechanic at least once a year or every 12,000 miles (19,000 km), whichever comes first.
Typical Replacement Intervals
While the exact replacement interval can vary, here are some general guidelines for replacing air suspension components:
- Air Bags: Air bags typically last between 50,000 to 100,000 miles (80,000 to 160,000 km) before needing replacement.
- Air Compressor: The air compressor, which supplies air to the suspension system, may need replacement every 75,000 to 100,000 miles (120,000 to 160,000 km).
- Suspension Sensors: Suspension sensors, such as ride height sensors, may need replacement every 50,000 to 100,000 miles (80,000 to 160,000 km).
- Other Components: Other air suspension components, such as air lines, valves, and bushings, may need replacement as part of routine maintenance or when issues are identified.
It's important to note that these are general guidelines, and the actual replacement intervals may vary based on the specific vehicle, driving conditions, and maintenance history. Regular inspections and following the manufacturer's recommended maintenance schedule are crucial to ensuring the longevity and proper functioning of the air suspension system.
When should air suspension be replaced?
Typically, a high-quality air spring should be replaced every six to ten years. Outside conditions including climate, road conditions, and constant abrasion of dirt and road debris also influence the functioning and life span of these air suspension components.
Does air suspension need maintenance?
The good news is that most air bag suspension systems are pretty self-sufficient and require little maintenance.
What is the life expectancy of air suspension?
The lifespan of an air suspension system varies depending on the component. The air tank, when properly maintained, can last a lifetime. The air lines and air management system's lifespan can vary, while the valve manifold typically lasts between 3-5 years. Air struts or air bags can last between 80,000-100,000 miles.
How long does air suspension usually last?
80,000 to 100,000 miles
Air springs normally last 80,000 to 100,000 miles. Over this time, the rubber bladder dries out, and cracks appear around the bottom piston. Compressors usually wear out because of leaky air springs.
