Locate the rear axle and help keep your suspension geometry in check with the Delphi Suspension Trailing Arm TC5848 — if you're shopping for an Expedition trailing arm, this drops in as a direct-fit replacement for the 1997-2002 Ford Expedition and 1998-2002 Lincoln Navigator. This is a rear lower trailing arm that locates the axle and helps control wheel movement over the road.

  • OE-derived engineering: built on Delphi's OE expertise, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket part.
  • Validated for the extremes: tested below -40°C and over 120°C and exposed to 720 hours of salt spray.
  • Inspected construction: 100% crack detection and ultrasonic flaw detection confirm the materials match OE specifications, with robot welding for consistent quality.
  • Precision joints: ball studs machined to micron tolerances for durable, smooth joint operation, plus anti-corrosion protection applied to each part.

Signs this part may need replacing include clunking or knocking from the rear, uneven rear tire wear, or a rear axle that shifts under acceleration or braking — diagnose the cause before replacing, as these symptoms can have other sources.
