Detailed Description

This Dorman suspension control arm is designed for Mercedes-Benz rear suspension service where the original arm has worn bushings, loosened joints, or developed handling noise. The aluminum body, rubber bushing, and coated finish support a factory-style replacement for the rear right upper forward location. It is a strong fitment choice for Mercedes-Benz S450, S550, S500, S63 AMG, CL550, and related models, including applications such as Fits 2018-2020 Mercedes-Benz S450, Rear Right Upper Forward and Fits 2007-2017 Mercedes-Benz S550, Rear Right Upper Forward. This part cross-references Mevotech Supreme CMS101092 for the same application.

What It Helps Fix

• Rear suspension clunking or knocking from worn control arm bushings
• Excessive play in the rear right upper forward suspension link
• Uneven rear tire wear caused by suspension geometry wear
• Loose or unstable rear-end handling on Mercedes-Benz S-Class and CL-Class vehicles
• Noise from deteriorated rubber bushings in the frame-to-knuckle link

Installation Notes and Tips

Verify the rear right upper forward position before installation, since this arm is not adjustable and is specific to the frame-to-knuckle location. Mounting hardware is not included, and the ball joint is not preinstalled. For best results, inspect adjacent suspension components and confirm alignment after replacement on Mercedes-Benz S450, S560, S550, S63 AMG, and CL550 applications.
