Detailed Description

Delphi TC8382 is engineered for the front left lower rearward suspension position and is compatible with 2013-2019 Cadillac ATS, 2017 Cadillac CTS, and 2020-2022 Cadillac CT4. This assembly combines an aluminum control arm with an included ball joint, bushings, dust boot, locking nut, and mounting hardware for a direct replacement on the specified applications. Delphi applies OE dimensional and material analysis to help ensure proper alignment of the aftermarket part with the original suspension layout. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Front-end clunking or looseness from a worn control arm assembly
• Uneven tire wear caused by suspension geometry issues
• Steering wander or reduced directional stability
• Excess play from a worn ball joint or deteriorated bushings
• Noise over bumps from damaged suspension pivot points

Installation Notes and Tips

Fits 2013-2019 Cadillac ATS, front left lower rearward. Fits 2017 Cadillac CTS, front left lower rearward. Fits 2020-2022 Cadillac CT4, front left lower rearward. Verify the vehicle’s suspension configuration and position before installation, and inspect related components such as the tie rod ends, strut, and alignment settings during service. Because this assembly is non-adjustable, final wheel alignment should be checked after replacement.

Quality Assurance

Delphi subjects steering and suspension parts to extreme temperature testing from below -40 degrees C to above 120 degrees C, along with 720 hours of salt spray exposure. The brand also uses dimensional and material analysis to support OE-level fit and compatibility for the listed Cadillac ATS, Cadillac CTS, and Cadillac CT4 applications.
