When your 2015 Ram 1500's air suspension fails to level properly, the truck may sag, sit too high, or have uneven ride height. The air suspension system provides adjustable ride height and automatic load leveling, but requires all components functioning correctly.
Air Suspension Components
The system includes air springs at each corner, an air compressor, a reservoir tank, height sensors, control module, and connecting lines. Failure in any component affects the system's ability to maintain proper ride height.
Common Leveling Problems
The truck sagging at one corner suggests a leaking air spring or failed height sensor. Failure to lift when loaded indicates compressor weakness or line leaks. Sitting too high suggests stuck height sensors or control module issues.
Air Spring Leaks
Air springs develop leaks at the rubber bellows or seal points. Slow leaks cause gradual sagging over time. Major leaks cause rapid height loss. Leaking springs are the most common cause of leveling problems.
Compressor Issues
The compressor works continuously to maintain pressure. Overworked compressors from leaking springs burn out. A failed compressor can't inflate springs to proper height. The compressor relay and fuse are also potential failure points.
