Detailed Description
Delphi TC5400 is engineered as a front upper suspension ball joint for the Cadillac CTS, covering 2003 through 2007 model years.

Delphi applies OE-focused dimensional and material analysis to support fitment consistency between original and replacement components. This part cross-references MOOG Chassis Products K500119 for the same application.
Common Repair Symptoms
- Front-end clunking or popping over bumps
- Excessive play in the upper suspension joint
- Uneven tire wear related to worn suspension geometry

Installation Notes and Tips
Because this is a pressed ball joint, proper removal and installation tools are required. Inspect the surrounding control arm, fasteners, and alignment settings before reassembly. Verify the tapered stud orientation, torque all hardware to vehicle specifications, and perform a wheel alignment after installation on the Cadillac CTS.
Quality Assurance
Delphi tests steering and suspension components under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt-spray testing. The TC5400 is built to OE-focused standards for material durability and dimensional accuracy in front upper suspension service.
