Detailed Description

Delphi TC7246 is engineered for the rear left upper suspension position on the Cadillac CTS from 2003 through 2007. The assembly includes the control arm, ball joint, bushings, dust boot, and mounting hardware, helping simplify replacement of a worn rear suspension link. Its aluminum construction and OE-based dimensional checks support proper alignment and consistent suspension movement.

Delphi applies OE-level testing to its aftermarket steering and suspension portfolio, including exposure to extreme temperatures and extended salt-spray testing. That validation process helps ensure the TC7246 meets the demands of daily driving while maintaining fitment accuracy for the Cadillac CTS rear suspension.

This part cross-references Dorman OE Solutions 522-489 and Mevotech Supreme CMS501176 for the same application.

Common Repair Symptoms

• Rear suspension clunking or knocking over bumps
• Uneven tire wear caused by worn suspension geometry
• Loose or unstable rear-end handling
• Excessive play from a worn ball joint or bushing
• Alignment issues after suspension wear

Installation Notes and Tips

Install Delphi TC7246 on the rear left upper position only for the listed Cadillac CTS applications. Because the ball joint is press-in and the assembly is not adjustable, proper removal and installation tools are important for a clean repair. Always verify alignment after replacement and inspect adjacent rear suspension components for wear before final assembly.

Quality Assurance

Delphi uses OE-focused engineering, dimensional analysis, and material validation to support fit and performance consistency. The part is tested for temperature extremes and salt-spray exposure to help confirm durability in real-world suspension service.
