Detailed Description

Delphi TC8407 is engineered as an OE-style suspension control arm and ball joint assembly for the front right lower rearward location. Delphi applies dimensional and material analysis to help maintain proper fit and compatibility with the original suspension layout, while testing components across extreme temperatures and extended salt spray exposure to validate durability. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2013-2019 Cadillac ATS, front right lower rearward; 2017 Cadillac CTS, front right lower rearward; and 2020-2022 Cadillac CT4, front right lower rearward. Delphi TC8407 is a direct-fit service part for Cadillac ATS front right lower rearward suspension repair, Cadillac CTS front right lower rearward replacement, and Cadillac CT4 front right lower rearward control arm service.

What It Helps Fix

• Front-end clunking or knocking from a worn ball joint
• Excessive play in the front right lower rearward suspension
• Uneven tire wear caused by worn control arm bushings
• Steering wander or reduced front suspension stability
• Noise or looseness from deteriorated rubber components

Installation Notes

• Verify vehicle fitment by year, make, model, and front right lower rearward position before installation.
• Press-in ball joint design requires the correct service tools and procedures.
• Inspect adjacent suspension components, alignment angles, and fasteners during replacement.
• Because the assembly is pre-greased and non-greaseable, no routine lubrication point is provided.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its steering and suspension portfolio. TC8407 is built with premium materials and tested for temperature extremes and corrosion exposure to support consistent service performance in Cadillac ATS, CTS, and CT4 applications.
