- Extreme-condition testing: Delphi tests its parts at temperatures below -40°C and above 120°C and exposes them to 720 hours of salt spray.
- Flaw detection: Delphi's arms go through 100% crack detection and ultrasonic flaw detection to confirm the materials match OE specifications.
- Dimensional and material analysis: Extensive checks are aimed at close compatibility between the OE part and the aftermarket part.
- Anti-corrosion protection: Applied to each part to help prevent corrosion and improve its appearance.
Signs a trailing arm may need replacing include clunking or knocking from the rear over bumps, a vague or wandering feel, uneven rear tire wear, or an arm that is visibly bent or damaged.
