Front Upper Ball Joint for 2005-2011 Cadillac STS & More - Delphi TC5907

Keep your steering tight and your suspension pivoting smoothly with the Delphi ball joint TC5907, a front upper suspension ball joint that drops in as a direct-fit replacement for the 2004-2009 Cadillac SRX and 2005-2011 Cadillac STS. The ball joint links the control arm to the steering knuckle, letting the front suspension articulate and steer while carrying load. If a worn front upper ball joint is behind your clunking, loose steering, or uneven tire wear, this replaces it.

OE-derived design: Delphi applies its OE steering expertise to this aftermarket joint, validating it below -40°C and above 120°C plus 720 hours of salt-spray exposure.

• High-quality forgings: built for increased strength and smooth operation.
• Chloroprene rubber boot: improves durability and helps prevent premature failure.
• Micron-tolerance machining: supports durable, smooth joint operation.
• Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

See the "Vehicles it fits" section for the full engine-level fitment.
