Help keep your rear wheels properly located with the Delphi TC5739, a rear lower Mazda 3 control arm built as a direct-fit replacement for the 2004-2012 Mazda 3, the 2012 Mazda 3 Sport and the 2006-2010 and 2012 Mazda 5. As a suspension control arm, it links the rear wheel assembly to the vehicle's body, letting the wheel travel up and down with the suspension while helping hold it in position.
Every Delphi control arm draws on the company's original-equipment background. Delphi's OE safety technology is fitted to millions of vehicles worldwide, and that expertise carries into its aftermarket steering portfolio.
- Tested to extremes: Delphi steering parts are tested at temperatures below -40°C and above 120°C and exposed to 720 hours of salt spray, backed by dimensional and material analysis for close compatibility with the OE part.
- Crack and flaw detection: each arm undergoes 100% crack detection and ultrasonic flaw detection to check its materials against OE specifications.
- Robot welding: used for consistent performance and quality.
- Anti-corrosion protection: applied to each part for corrosion prevention and a clean appearance.
Signs a rear lower control arm may need replacing include clunking from the rear over bumps, uneven tire wear, wandering or loose handling, or a visibly bent or damaged arm. Diagnose the cause before replacing, and have the wheel alignment checked after installation. See the Buyer's Guide tab for complete fitment details.
