Detailed Description

The Delphi TC4868 lateral arm is engineered as a suspension replacement part for the rear lower forward location. Its forged aluminum body helps maintain strength while keeping the design aligned with OE-style suspension architecture, and the included rubber bushings support controlled movement at the mounting points. This part number TC4868 is a practical service solution when replacing worn rear suspension links on Mercedes-Benz CLA250, CLA45 AMG, and GLA45 AMG vehicles.

Delphi validates parts through extreme temperature exposure and salt-spray testing, along with dimensional and material analysis to support OE-level fit and compatibility. This makes the TC4868 a focused replacement for restoring rear suspension alignment and link integrity on the specified Mercedes-Benz applications.

What It Helps Address

• Excessive rear suspension play from worn bushings
• Clunking or knocking from the rear lower forward link area
• Uneven rear tire wear related to suspension geometry issues
• Imprecise rear-end handling caused by a fatigued lateral arm
• Corrosion-related replacement needs on aging suspension components

Installation Notes and Tips

Install TC4868 at the rear lower forward suspension position only on the listed Mercedes-Benz applications. Because mounting hardware is not included, reuse or source the correct hardware separately if required by the vehicle. After installation, verify suspension fastener torque at ride height and perform a wheel alignment if the vehicle manufacturer specifies it after rear suspension service.

Quality Assurance

Delphi uses OE-focused engineering and testing methods for its steering and suspension portfolio. This part is evaluated for temperature resistance, corrosion exposure, and dimensional accuracy to support consistent replacement quality for Mercedes-Benz CLA250, CLA45 AMG, and GLA45 AMG service work.
