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 a long list of BMW applications, including the 2012-2016 BMW 528I XDRIVE, 2011-2016 BMW 535I XDRIVE, 2011-2016 BMW 550I XDRIVE, 2010-2015 BMW 750LI XDRIVE and 2011-2015 BMW ALPINA B7 XDRIVE.
- 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 steering and suspension expertise to the aftermarket, 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.
