  • Fits 2020-2025 Cadillac CT4, front left lower forward
  • Fits 2013-2019 Cadillac ATS, front left lower forward
  • Steel stamped control arm with black finish

  • Machined ball joint mounting with threaded stud design
  • Mounting hardware included
  • Rubber bushing material for OE-style suspension compliance

Fitment and Application Details

This suspension control arm assembly is engineered for Cadillac CT4 and Cadillac ATS front left lower forward applications. The Dorman 526-243 part number is a practical OE-style replacement when the original control arm shows wear, looseness, or alignment-related issues. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

  • Clunking or knocking from the front suspension
  • Excessive play in the lower control arm assembly
  • Uneven tire wear related to worn suspension geometry
  • Steering wander or reduced directional stability
  • Handling noise caused by a deteriorated OE control arm

Installation Notes and Tips

Confirm the vehicle position before installation: front left lower forward. Inspect adjacent suspension components, fasteners, and alignment settings during replacement. Because the ball joint is already installed and the assembly includes mounting hardware, installation is streamlined compared with rebuilding the arm. After installation, a professional wheel alignment is recommended.

Quality Assurance

Dorman uses an industry-focused evaluation process to verify fit, function, and suspension performance characteristics for this replacement control arm assembly. The design supports OE-style ride control and predictable dynamics for Cadillac CT4 and Cadillac ATS applications.
