Pin down steering play and restore 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 the 2007-2013 Volvo C30, 2006-2013 Volvo C70, 2006-2011 Volvo S40 and 2006-2011 Volvo V50 (see the Buyer's Guide tab for 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. Ball joints work as a matched set; inspect and, where worn, replace the opposite side for balanced steering.

What position is this ball joint?
It is a front lower suspension ball joint for the listed Volvo applications.
What does a ball joint do?
It connects the control arm to the steering knuckle, letting the front wheel steer and move through suspension travel while keeping the joint located.
What are the signs of a worn ball joint?
Common signs include clunking over the front suspension, loose or wandering steering, and uneven tire wear. Diagnose the cause first, since other parts can produce the same symptoms.
Should I replace both sides at once?
