Steady your ride with the Delphi control arm TC6221, a rear lower suspension control arm that installs as a direct-fit replacement on the 2007-2010 Dodge Caliber, 2007-2009 Jeep Compass, and 2007-2009 Jeep Patriot. The control arm links the frame to the wheel knuckle, locating the wheel and guiding its motion through suspension travel while the machined ball stud lets the joint articulate.
Delphi applies its OE expertise to this aftermarket part, testing to the extreme for OE performance:
- Tested to OE extremes: validated below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
- 100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Robot-welded: welded by robot for consistent quality and performance.
- Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Signs of a worn rear lower control arm or its ball joint include clunking over bumps, uneven rear tire wear, and vague handling; if a failed control arm is the cause, this replaces it. See the "Vehicles it fits" section for the engine details on your application.
