What It Helps Address

• Excessive rear suspension play
• Clunking or knocking from the rear upper suspension area
• Uneven tire wear related to worn suspension joints
• Loose or imprecise rear suspension response
• Inspection failure caused by worn ball joint components

Installation Notes

Verify rear upper position fitment before installation on Cadillac CTS, Cadillac STS, or Cadillac SRX applications. Inspect the surrounding suspension components, mounting points, and fasteners for wear or damage before replacing the joint. Because mounting hardware is not included, reuse or source the required hardware separately as needed.

Quality Assurance

Delphi subjects its OE-style parts to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing. That validation supports durability expectations for daily-driven Cadillac CTS, STS, and SRX rear suspension service. Part number TC8341 is engineered with OE compatibility in mind for the listed applications.
