Help tighten up a loose, clunky ride with the Delphi control arm TC6223, a rear lower control arm that drops in as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1998-2011 Ford Crown Victoria, 1998-2011 Lincoln Town Car and 1998-2011 Mercury Grand Marquis; see the "Vehicles it fits" section for the full list. It connects the suspension to the chassis and helps locate the wheel, so a worn arm can show up as clunking over bumps, vague or wandering steering, and uneven tire wear — if a failed control arm is the cause, this replaces it.
- OE-level validation: Delphi applies its OE steering expertise here, testing below -40°C and above 120°C and exposing parts to 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
- 100% flaw inspection: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Robot welding & micron-machined studs: robot welding delivers consistent quality, and the ball studs are machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
A great match if you're shopping for 1998-2011 Ford Crown Victoria rear control arms or a 1998-2011 Lincoln Town Car control arm.
