Front Left Rearward Control Arm with Ball Joint for 2009-2014 CL550

In this review of the Front Left Rearward Control Arm with Ball Joint the bottom line is straightforward: this is a direct-fit OE replacement for owners of compatible Mercedes-Benz models who need a like-for-like lower rearward control arm. It is aimed at DIY mechanics and independent shops that value part interchangeability and clear OE reference numbers. The product stands out because it replaces the entire control arm and ball joint assembly as a single piece, making installation and alignment checks simpler compared with piecemeal repairs.

Key Features

• Direct Fit: Designed to match the original mounting points so the control arm installs without major modification on the listed Mercedes models.
• OE Replacement Assembly: Includes the control arm and ball joint as one unit, reducing complexity and ensuring consistent suspension geometry after install.
• Vehicle Specific Fitment: Listing includes clear compatibility notes for CL550, S550, S350 and S450 model years to help buyers confirm fit before purchase.
• Aluminum Construction: The control arm material is aluminum to balance strength and weight savings compared with heavier steels.
• Bushings Included: Supplied with bushings so the part is ready to fit and does not require sourcing additional components.
• Multiple Reference Numbers: Supplied with OE and aftermarket reference numbers to ease cross-referencing during parts lookup.

Who It's For

This control arm is best for owners of 2007-2014 Mercedes-Benz S and CL models listed in the fitment who want a direct OE-style replacement without paying dealer prices. It suits knowledgeable DIYers and independent repair shops that handle suspension jobs and wheel alignment afterwards.

It is not intended for owners who need a fully adjustable performance suspension arm or for those whose vehicles fall outside the exact years and side listed; buyers should check the vehicle-specific compatibility information in the listing before ordering.
