Keep the front suspension tight and the steering responsive with the Delphi ball joint TC3645, a front lower ball joint that pivots between the lower control arm and the steering knuckle so the wheel can steer and travel while locating the suspension. It installs as a direct-fit replacement on many vehicles, among them the 2001-2007 Dodge Grand Caravan, 2001-2007 Chrysler Town & Country and 2001-2007 Dodge Caravan; see the "Vehicles it fits" section for the full list and engine-level detail.
- Forged build: manufactured from high-quality forgings for increased strength and smooth operation.
- Chloroprene boots: ball joints use chloroprene rubber boots that improve durability and help prevent premature failure.
- Micron-tolerance machining: machined to micron tolerances for durability and smooth joint operation.
- Corrosion protection: anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.
Backed by Delphi's OE testing — parts are run below -40°C and above 120°C and exposed to 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket matching. If a worn front lower joint is the cause of clunking over bumps, loose steering, or uneven tire wear, this replaces it.
