Delphi Suspension Ball Joint P/N:TC5640

Keep the front suspension pivoting smoothly with the Delphi ball joint TC5640, a front lower suspension ball joint that connects the control arm to the steering knuckle and lets the wheel move through steering and travel. It's a direct-fit replacement for the 2007-2012 Mazda CX-9 — see the Buyer's Guide tab for engine-level fitment.

Delphi applies its OE expertise to its aftermarket steering portfolio, testing to the extreme for OE performance: the part withstands temperatures below -40°C and over 120°C and is exposed to 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.

• Forged construction: manufactured with high-quality forgings for increased strength and smooth operation.
• Chloroprene rubber boot: improves durability and helps prevent premature failure.
• Micron-tolerance machining: machined to micron tolerances for durability and smooth joint operation.
• Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.

Signs this ball joint may need replacing include clunking or knocking over bumps or when turning, loose or wandering steering, and uneven tire wear. Diagnose the cause before replacing, since these symptoms can have other sources.
