Keep the front suspension tight and the steering precise with the Delphi ball joint TC2379, a front lower ball joint that connects the control arm to the steering knuckle, letting the knuckle pivot for steering and suspension travel while helping locate the front wheel. It's a direct-fit replacement for a wide range of Mercedes-Benz SUVs and wagons, including the 2007-2012 GL450 and 2010-2012 GL350, 2008-2012 GL550, 2007-2009 GL320, 2007-2009 ML320, 2006-2011 ML350, 2010-2011 ML450, 2006-2007 ML500, 2008-2011 ML550, 2007-2011 ML63 AMG, 2007-2009 R320, 2006-2012 R350, 2006-2007 R500 and 2007 R63 AMG — see the Buyer's Guide tab for the full list and engine coverage.
- Forged for strength: built with high-quality forgings for increased strength and smooth operation.
- Chloroprene rubber boot: improves durability and helps prevent premature failure by keeping contaminants out.
- Micron-tolerance machining: machined to micron tolerances for durable, smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Delphi's OE safety technology is fitted to millions of vehicles worldwide, and this aftermarket steering part draws on that OE expertise — tested below -40°C and over 120°C plus 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility. If a worn front lower ball joint is behind clunking on acceleration or braking, loose steering or uneven tire wear, this replaces it. Sold individually; replacing both sides together as a matched pair is recommended for balanced steering and handling.
