This Delphi ball joint is engineered for select Cadillac CTS, Cadillac STS, and Cadillac SRX front suspension applications.

The part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. This part cross-references Dorman OE Solutions 521-021 for the same application.
Common Problems This Part Can Address

Installation Notes
Delphi TC7135 uses a pressed mounting design, so installation requires proper suspension service tools and correct press procedures.

Always confirm alignment after replacing a front left lower ball joint.
