| Step 1: Check that the upper and lower mounting points of the air spring are tight and that there is no metal contact with the vehicle chassis or axle. |
| Step 2: Inspect whether the air spring rubs against surrounding components (e.g., brake lines, wiring harness) during inflation and deflation. |
| Step 3: If the noise is from the air compressor, check if its mounting bolts are loose and if the intake air filter is clogged. |
