Delphi's OE safety technology is fitted to millions of vehicles worldwide, and the company brings that OE expertise to its aftermarket steering portfolio. Delphi tests to the extreme for OE performance, and its dimensional and material analysis is aimed at close compatibility between the OE and aftermarket part.
- Extreme-condition testing: Delphi parts withstand temperatures below -40°C and above 120°C and are exposed to 720 hours of salt spray.
- Inspected and robot-welded: Each arm undergoes 100% crack detection and ultrasonic flaw detection to check that materials match OE specifications. Robot welding is used for consistent performance and quality.
- Precision ball studs: The ball studs are machined to micron tolerances, intended to support durability and smooth joint operation.
- Anti-corrosion protection: A protective treatment is applied to each part to resist corrosion and improve its appearance.
Clunking from the rear over bumps, loose or wandering handling, and uneven tire wear are signs this part may need replacing. Other suspension components can cause similar symptoms, so diagnose the cause before replacing.
