Help take up steering play and support smooth articulation with the Delphi ball joint TC1971, a front lower suspension ball joint that connects the control arm to the steering knuckle so the wheel can steer and travel while the suspension moves. It drops in as a direct-fit replacement for many Volvo models, among them the 2008-2010 Volvo C30, 2006-2010 Volvo C70 and 2006-2010 Volvo S40 (see the "Vehicles it fits" section for the full list and engine-level detail).
Delphi builds this joint on its OE safety heritage, validating parts through extensive dimensional and material analysis for close OE-to-aftermarket compatibility, with testing that spans below -40°C to above 120°C plus 720 hours of salt-spray exposure.
- High-quality forging: forged construction 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 appearance.
Signs this part may need replacing include clunking over the front suspension, loose or wandering steering, and uneven tire wear — diagnose the cause before replacing, since a worn ball joint is one of several possible sources. This listing is for one ball joint; replacing both sides together is recommended for balanced steering.
