Front Left Lower Control Arm with Ball Joint for 2003-2007 Mercedes

In this review of the Front Left Lower Control Arm with Ball Joint, the reviewer focuses on drivers of 4Matic Mercedes C-Class models from 2003 through 2007 who need a direct OE-style replacement. The bottom line: this assembly is a straightforward, vehicle-specific swap that restores proper front suspension geometry without paying dealership prices. It is best for a DIY mechanic or a repair shop seeking a steel, OE-replacement control arm with a pre-mounted ball joint and included bushings to speed installation and maintain factory fitment.

Key Features

• Direct fit: Designed to match factory dimensions so it installs in place of the original arm with minimal adjustment required.
• OE replacement assembly: Combines the control arm and ball joint into one unit so the suspension is rebuilt to a factory-like configuration.
• Vehicle specific fitment: Coverage for 2003-05 C240 and C320 and 2006-07 C280 and C350 4Matic front driver side lowers reduces guesswork when ordering.
• Steel construction: A durable steel arm provides the stiffness expected for control arms on heavier all-wheel-drive C-Class variants.
• Bushings included: Ships with bushings and a machined ball joint mount so little extra hardware is needed during replacement.
• OE reference compatibility: Matches multiple reference numbers used for sourcing or cross-referencing with original parts.

Who It's For

This control arm is a good fit for owners of the specified Mercedes-Benz C-Class 4Matic models who want an OE-style, direct replacement without modifying the vehicle. It works well for independent mechanics, DIYers with basic suspension experience, and service shops that need a ready-to-install lower control arm and ball joint assembly.

Those who should look elsewhere include drivers with non-4Matic models or earlier/later model years not listed, and anyone who requires a greaseable ball joint or an adjustable control arm for alignment tuning. For cars outside the stated fitment, confirm compatibility using vehicle-specific check fitment information before purchase.
