Keep your rear suspension located and quiet with the Delphi control arm (TC6231), a direct-fit rear upper replacement for the 2004-2012 Chevrolet Malibu, 2005-2010 Pontiac G6, and 2007-2009 Saturn Aura. It locates the rear suspension and, through its ball stud, helps control wheel movement for stable handling and even tire wear.
Delphi applies its OE steering and suspension expertise to this aftermarket part, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility. Delphi tests to the extreme: parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray.
- Validated to OE specs: undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Robot-welded: uses robotic welding for consistent quality and performance.
- Precision ball studs: ball studs machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and improved appearance.
Worn control-arm bushings or a loose ball joint can cause clunking on bumps, vibration, or uneven tire wear; if the rear upper arm is the cause, this replaces it. Replace both sides as a matched pair for balanced handling.
