Detailed Description

Delphi TD4223W is a front lower suspension control arm bushing engineered for direct replacement service on select Mercedes-Benz vehicles. It uses a rubber and steel design with press-in installation, making it suitable for restoring the control arm’s bushing interface where wear can affect suspension feel and alignment stability. This part number, TD4223W, is listed for 2007-2014 Mercedes-Benz CL600, 2009-2014 Mercedes-Benz CL550, 2012-2013 Mercedes-Benz S350, 2011-2013 Mercedes-Benz S400, 2007-2013 Mercedes-Benz S550, 2011-2013 Mercedes-Benz S600, and 2008-2011 Mercedes-Benz S450, all in the front lower position.

This part cross-references Beck/Arnley (e.g., 102-7779, 102-7780) for the same application.

What It Helps Address

• Excessive play in the front lower control arm bushing
• Clunking or knocking from worn suspension bushings
• Uneven tire wear related to bushing deterioration
• Loose or imprecise steering response from front suspension wear
• Suspension noise caused by cracked or separated rubber

Installation Notes

Press-in installation is required, so proper suspension service tools or a professional press setup are recommended. Confirm the front lower position and verify the original bushing dimensions before installation. Because mounting hardware is not included, reuse or replacement hardware should be evaluated during service. Always inspect the control arm and surrounding suspension components for wear before pressing in the new bushing.

Quality Assurance

Delphi subjects its OE-based suspension and steering parts to extreme temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. These validation steps support durability and corrosion resistance expectations for aftermarket service on Mercedes-Benz CL550, S550, and related applications.
