Front Right Upper Control Arm with Ball Joint for 2000-2006 Mercedes

In this review of the Front Right Upper Control Arm with Ball Joint, the bottom line is simple: this assembly is for owners of 2000-2006 Mercedes-Benz CL and S-Class models who need a direct-fit, OE-style replacement that restores factory suspension geometry. The reviewer found it best for routine replacement or repair when the original control arm or ball joint shows wear. Installation is straightforward for a competent DIYer or a shop, and the part matches OE reference numbers used across several Mercedes models, which simplifies fitment checks.

Key Features

• Direct Fit: The assembly is designed as a direct OE replacement so it aligns with factory mounting points and reduces fitment guesswork.
• Integrated Ball Joint: The control arm comes with a preinstalled ball joint, which speeds up installation and avoids separate sourcing of components.
• Vehicle Specific Fitment: Fitment information covers a wide range of 2000-2006 CL and S-Class variants so buyers can confirm compatibility before purchase.
• OE Reference Matching: The part lists OE reference numbers such as 2203301507 and 2203308407 to help verify correct replacement against the original part.
• Aftermarket Cross References: Multiple aftermarket reference numbers are provided so installers and parts departments can cross-check alternative suppliers or catalogs.
• Replacement Suspension Component: Built to replace a worn upper control arm and ball joint assembly, restoring steering and suspension feel when the original fails.

Who It's For

This product is aimed at owners and technicians working on 2000-2006 Mercedes-Benz CL500, CL55 AMG, CL600, CL65 AMG and S-Class models (including S350, S430, S500, S55 AMG, S600, S65 AMG) who need a passenger-side front right upper control arm replacement. It suits those who prefer a single-piece assembly with the ball joint already installed to simplify repair time.

It is less appropriate for someone who requires a custom or performance suspension upgrade, since this is an OE-style replacement rather than a modified or heavy-duty component. Also, buyers should verify the detailed fitment notes for their exact model and year before ordering.
