Detailed Description

Delphi applies OE engineering knowledge to its aftermarket steering and suspension portfolio, and TC7733 reflects that approach with dimensional and material analysis focused on fit and function. This rear suspension control arm is built for the rear right forward upper location and is engineered for Mercedes-Benz CL-Class and S-Class applications that require a precise replacement part. The combination of steel and aluminum construction, straight shape, and rubber bearing type supports stable suspension geometry while maintaining the ride characteristics expected in these vehicles. This part cross-references Beck/Arnley 102-6803 for the same application.

Common Problems This Part Addresses

• Excessive rear suspension play or looseness
• Clunking or knocking from the rear suspension area
• Uneven tire wear caused by worn control arm bushings
• Imprecise rear-end alignment or handling response
• Cracked or deteriorated rubber bushings in the upper rear suspension link

Installation Notes and Tips

Install Delphi TC7733 in the rear right forward upper position only. Verify the existing arm length, mounting points, and vehicle application before installation, especially on Mercedes-Benz CL550, S550, and related CL-Class and S-Class models. Because mounting hardware is not included, inspect fasteners and related suspension components for wear before reassembly. A professional alignment is recommended after suspension work is completed.

Quality Assurance

Delphi subjects its OE-style suspension components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. TC7733 is built to support OE-level fitment consistency for the listed Mercedes-Benz applications.
