Keep the rear wheels tracking straight and soak up road impacts with the Delphi Suspension Trailing Arm TC5766 — a direct-fit rear Hyundai Sonata trailing arm replacement that locates the wheel, controls its fore-and-aft movement, and helps tie the rear suspension to the chassis. It installs on the 1999-2005 Hyundai Sonata, 2001 Hyundai XG300, 2002-2005 Hyundai XG350, 2001-2006 Kia Optima, and 2004-2006 Kia Amanti; see the Buyer's Guide tab for engine-level fitment.

  • OE-validated testing: Delphi applies its OE expertise to the aftermarket line, with parts tested below -40°C and above 120°C and exposed to 720 hours of salt spray, plus dimensional and material analysis for OE compatibility.
  • Inspected materials: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
  • Robot welding: used for consistent performance and quality.
  • Machined ball studs: finished to micron tolerances for durable, smooth joint operation, with anti-corrosion protection applied for corrosion prevention and enhanced aesthetics.

Signs this rear trailing arm may need replacing include clunking over bumps or under acceleration, loose or wandering rear tracking, and worn or corroded joints.

Yes. It is cataloged for the 1999-2005 Hyundai Sonata, along with the Hyundai XG300, XG350, Kia Optima, and Kia Amanti. Check the Buyer's Guide tab to confirm your vehicle.

Is this a front or rear part?

It is a rear suspension trailing arm for the listed applications.

How was this Delphi part tested?

Delphi tests below -40°C and above 120°C and exposes parts to 720 hours of salt spray, with dimensional and material analysis for OE compatibility and 100% crack and ultrasonic flaw detection.

What are signs my trailing arm needs replacing?

Clunking over bumps or under acceleration, loose or wandering rear tracking, and worn or corroded joints. Diagnose the cause before replacing, as other suspension parts can produce similar symptoms.
