Rear Left Trailing Arm for 2011-2015 Ford Edge & More - Delphi TC9046

Keep the rear wheel located and tracking correctly with the Delphi Suspension Trailing Arm (TC9046), a direct-fit rear left trailing arm that helps control the wheel's fore-and-aft movement over the road. It drops in as a replacement for the 2011-2013 Ford Edge and 2011-2013 Lincoln MKX — the Edge trailing arm many owners search for — with engine specifics listed under the "Vehicles it fits" section.

Delphi builds this arm with its OE engineering carried into the aftermarket steering and suspension portfolio, testing to the extreme for OE performance:

• OE-grade validation: parts withstand temperatures below -40°C and above 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
• Flaw inspection: 100% crack detection and ultrasonic flaw detection confirm materials match OE specifications.
• Robot welding: used for consistent quality from part to part.
• Micron-tolerance ball studs machined for durability and smooth joint operation, with anti-corrosion protection applied to each part for corrosion prevention and improved appearance.

Worn suspension bushings or a damaged trailing arm can cause clunks, uneven tire wear, or loose rear tracking; if the arm is the cause, this replaces it.
