Detailed Description

Moog RK623352 is a front left lower suspension control arm and ball joint assembly made for select Cadillac CTS models from 2003 through 2007 with the RPO Code E5A retuned chassis. This Moog control arm is a practical OE-style replacement for restoring suspension geometry, steering response, and joint integrity on the Cadillac CTS front suspension. The RK623352 part number is also referenced in aftermarket catalogs for the same application, including Delphi TC7640 and Dorman OE Solutions 521-019.

As a premium suspension component, this assembly combines the control arm, ball joint, and bushings in one service part. That makes it a focused solution for front-end wear on a Cadillac CTS front left lower suspension repair, especially when the original arm shows looseness, noise, or bushing deterioration. The Moog RK623352 is also cross-referenced with Mevotech Supreme CMS50190 for the same vehicle application.

• Clunking or knocking from the front suspension
• Excessive play in the lower control arm or ball joint

• Steering wander or reduced front-end stability
• Cracked, torn, or deteriorated control arm bushings
