Key Features

• Rubber construction for controlled compliance and vibration isolation
• Press-fit mounting type for OE-style installation
• Standard replacement grade for direct service use
• OE-focused dimensional and material analysis for fit consistency
• Engineered and tested for temperature extremes from below -40°C to over 120°C
• Exposed to 720 hours of salt spray testing for corrosion resistance validation
• Fits rear upper inner and rear right upper positions on select Mercedes-Benz applications

Detailed Description

The Delphi TD1104W suspension control arm bushing is built to restore the connection point between the control arm and chassis on compatible Mercedes-Benz vehicles. Its rubber construction helps maintain suspension articulation while reducing unwanted movement, and its OE-based sizing supports proper fit at the rear upper inner location. This part number, TD1104W, is a practical choice for service work on Mercedes-Benz S65 AMG, CL600, CL63 AMG, CL65 AMG, S550, and related applications where the original bushing has worn, cracked, or loosened.

Delphi applies OE-level dimensional and material analysis to improve compatibility between the original part and the aftermarket replacement. The bushing measures 0.476 in. inside diameter, 1.634 in. outside diameter, and 1.587 in. height, with a 0.579 in. wall thickness. This part cross-references Beck/Arnley 102-6802 and Dorman OE Solutions 521-485 for the same application.

What It Helps Address

• Clunking or knocking from the rear suspension
• Excessive control arm movement under load
• Uneven tire wear related to worn rear suspension bushings
• Loose or imprecise rear suspension feel
• Alignment instability caused by deteriorated bushing material

Installation Notes and Tips

TD1104W is a press-fit bushing, so proper removal and installation tools are recommended to avoid damaging the control arm or the new bushing. Confirm the rear upper inner or rear right upper position before ordering, and verify OE dimensions against the original component. This part is compatible with 2006-2016 Mercedes-Benz S65 AMG, 2006-2014 Mercedes-Benz CL600, 2007-2014 Mercedes-Benz CL550, 2011-2014 Mercedes-Benz CL63 AMG, 2008-2014 Mercedes-Benz CL65 AMG, 2007-2013 Mercedes-Benz S550, and other listed Mercedes-Benz applications.
