MOOG 08-15 Cadillac CTS Front Right Upper Control Arm and Ball Joint Assembly

If you're noticing some looseness in your steering or hearing clunks from the front end of your 2008-2015 Cadillac CTS, it might be time to look at the upper control arm and ball joint assembly. This Moog RK623173 is a direct replacement for your original part, designed to restore proper suspension geometry and steering response.

Moog builds these assemblies with a focus on longevity. The ball joint features a stud shape that's engineered for a long fatigue life, and the socket is sealed to keep contaminants out, meaning it's ready to go right out of the box with no maintenance needed. The control arm itself is heat-treated for strength, helping to prevent premature failure, and the bushings are optimized to handle road grime and oils while keeping things quiet. Plus, the studs are coated and the cast iron and steel control arms have an e-coat finish to help fight off rust.

This assembly comes pre-assembled with the ball joint, making installation more straightforward. It's designed to fit right, so you can get your alignment done with confidence after it's installed.
