Detailed Description

This Dorman suspension control arm and ball joint assembly is built as an OE-style replacement for the rear left upper location on the Cadillac CTS.

Common Problems This Part Addresses

Installation Notes and Tips

Compatible with 2003-2007 Cadillac CTS, rear left upper. Verify the mounting location, ball joint stud thread diameter, and suspension geometry before installation. Because the ball joint is already installed and the assembly is pre-greased, installation focuses on removing the worn OE unit and securing the replacement with the included mounting hardware. A professional alignment is recommended after suspension work.
