Failure Symptoms

The most common symptom is the vehicle sagging or leaning unevenly, indicating a loss of air pressure. This can progress to a constantly uneven ride height and potentially damage to suspension components. If the valve fails to hold air, the suspension may bottom out, compromising vehicle stability and cargo protection.

Installation Tip

Ensure all air lines are properly seated and secured to the valve ports to prevent air leaks. Avoid bending or kinking the air lines during installation, as this can restrict airflow.

Service Note

Inspect the suspension air springs (bellows) and air lines for cracks or leaks when replacing the height control valve.
