Delphi Suspension Ball Joint P/N:TC3666

Help keep steering tight and control-arm motion smooth with the Delphi ball joint TC3666, a front lower suspension ball joint that connects the lower control arm to the steering knuckle and lets the suspension pivot and travel while you steer. It's a direct-fit replacement for many BMW applications, including the 2010-2013 BMW 750I Xdrive, 2010-2013 BMW 750LI Xdrive and 2011-2013 BMW Alpina B7 Xdrive; see the Buyer's Guide tab for the full list.

• 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: Delphi machines to micron tolerances for durability and smooth joint operation.
• OE validation: tested to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray, with anti-corrosion protection applied for corrosion prevention and enhanced aesthetics.

Delphi applies its OE expertise to its aftermarket steering portfolio, using extensive dimensional and material analysis for close compatibility between the OE and aftermarket part. Signs a front lower ball joint may need replacing include clunking or knocking over bumps, loose or wandering steering, and uneven tire wear; diagnose the cause before replacing.
