Delphi TC7734 Suspension Control Arm - Rear Left Upper Forward

Delphi TC7734 Rear Left Upper Forward Control Arm

Delphi TC7734 is a standard replacement suspension control arm built for the rear left upper forward position. It uses steel and aluminum construction with a straight shape, natural rubber bushings, and OE-focused dimensional and material analysis for consistent fitment on select Mercedes-Benz applications.

Key Features

• Suspension control arm for the rear left upper forward position
• Steel and aluminum construction with casting/forged design
• Natural rubber bushings included; gray bushing color
• Straight shape with silver finish
• Standard replacement grade for OE-style service
• Not pre-greased and no grease fitting included
• No ball joint included
• No mounting hardware included

Detailed Description

Delphi TC7734 is engineered as a rear left upper forward suspension control arm for Mercedes-Benz CL-Class and S-Class vehicles. It is built with steel and aluminum materials and a casting/forged construction to match the demands of suspension service while maintaining OE-style dimensional accuracy. The included natural rubber bushings and rubber bearing type help restore proper suspension location and articulation in the rear suspension assembly.

This part cross-references Beck/Arnley 102-6802 and Dorman OE Solutions 521-485 for the same application. It is a direct-fit replacement for select Mercedes-Benz CL550, CL600, CL63 AMG, CL65 AMG, S350, S400, S450, S550, S600, S63 AMG, and S65 AMG models in the rear left upper forward position. Delphi TC7734 is a practical choice when replacing a worn rear suspension control arm on Mercedes-Benz CL550 or S550 applications.

What It Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from the rear suspension area
• Uneven tire wear caused by worn suspension geometry
• Excessive play from deteriorated control arm bushings
• Restoring rear wheel alignment consistency after suspension wear

Installation Notes and Tips

Install Delphi TC7734 in the rear left upper forward position only. Because mounting hardware is not included, inspect existing fasteners and replace any worn or damaged hardware as needed. After installation, a professional wheel alignment is recommended to verify rear suspension geometry and tire wear settings. Confirm vehicle application by year, model, and position before ordering.

Quality Assurance

Delphi applies OE engineering and validation practices to its aftermarket steering and suspension portfolio. This control arm is tested across extreme temperature ranges and salt-spray exposure, and Delphi uses dimensional and material analysis to support OE-level compatibility for the listed Mercedes-Benz applications.
