Suspension system differences

Air-spring height control and electronically controlled damping serve different functions. A sagging corner suggests air leakage or height-control trouble, while a damping warning may involve a damper, wiring or accelerometer input. Uneven tire wear may originate in alignment, bushings, tire pressure or ride height.

How a technician distinguishes the causes

Record the height at each wheel after parking and during commanded changes when air suspension is fitted. Inspect bags, fittings, compressor, relay, valve block and height sensors as appropriate. For Skyhook or adaptive dampers, scan the chassis controller and test circuits before replacing a shock. Inspect control arms and bushings before alignment.

Repair decisions and verification

After repair, verify ride height and calibrations if specified; road-test for noise and stability and recheck alignment and tire condition.

What owners may notice. A heavy coupe or convertible that clunks, wanders or wears tires unevenly may have suspension-joint wear, alignment issues or damper problems.

How the problem should be diagnosed. Inspect loaded suspension joints, tire wear and wheel condition; check electronic damping faults if equipped.

Repair and safety considerations. Alignment alone cannot correct a worn mechanical component.
