Delphi TC1492 Suspension Control Arm and Ball Joint Assembly - Front Left Upper

OE-Style Front Left Upper Control Arm

Delphi TC1492 is a front left upper suspension control arm and ball joint assembly for select Mercedes-Benz applications. It is built as a standard replacement part with OE-focused materials and dimensional checks for proper alignment and fit.

Key Features

• Pre-greased with a grease fitting included
• Ball joint uses a press-in mounting design
• Bushings included with neoprene rubber bushing material
• Control arm construction uses casting/forged design
• Mounting hardware included
• Non-adjustable front left upper suspension position
• Standard replacement grade for direct service work

Detailed Product Overview

Delphi applies OE engineering experience to its aftermarket steering and suspension portfolio, and the TC1492 follows that approach with dimensional and material analysis for fit consistency. The arm is designed for front left upper placement on Mercedes-Benz CL500, CL55 AMG, CL600, CL65 AMG, S350, S430, S500, S55 AMG, S600, and S65 AMG models listed in the fitment data. This Delphi TC1492 assembly is a practical choice when replacing a worn upper control arm on a Mercedes-Benz S-Class or CL-Class front suspension.

Material and durability testing are part of the design focus, including exposure to extreme temperatures and salt spray testing to evaluate corrosion resistance and long-term service behavior. The white control arm finish, aluminum-based construction, and included bushings support a direct replacement installation on the specified front left upper position.

This part cross-references Beck/Arnley 102-6147 and Mevotech Supreme CMS10135 for the same application.

Common Problems This Part Can Address

• Front-end clunking or knocking from a worn upper control arm
• Loose or inconsistent steering feel caused by bushing wear
• Uneven tire wear related to suspension geometry issues
• Excessive play from a failing ball joint assembly
• Alignment instability after suspension component wear

Installation Notes and Tips

Verify the vehicle’s front left upper suspension position before ordering, since this assembly is position-specific. Inspect adjacent suspension components, fasteners, and alignment settings during replacement, and perform a professional wheel alignment after installation. Confirm fitment against the vehicle’s exact model and year, especially on Mercedes-Benz CL500, S430, and related applications.

Quality Assurance

Delphi tests this suspension component for OE-level performance expectations, including extreme temperature exposure and extended salt spray testing. The brand also uses dimensional and material analysis to help maintain compatibility with the original equipment application.
