Front Left Lower Forward Control Arm with Ball Joint for Audi A8 S8

Our review of this control arm finds it best suited for Audi A8 and S8 owners needing a direct OE-style replacement; the single biggest reason to buy is its vehicle-specific fit and solid construction that closely matches original equipment. The reviewer replaced a worn lower forward control arm on a 2006 A8 Quattro and found the part arrived with the expected aluminum arm and machined ball joint mount, making the swap straightforward when the fitment checks in the listing matched the vehicle. This review focuses on fit, build quality, and real-world installation notes.

Key Features

• Direct Fit: Designed as an OE replacement so the control arm installs without fabrication or modification on compatible Audi A8 and S8 lower forward positions.
• Aluminum Construction: The aluminum arm provides a balance of strength and reduced unsprung weight for the front suspension.
• Integrated Ball Joint Assembly: Comes as a preassembled unit to simplify replacement and reduce labor time compared with separate components.
• Vehicle Specific Fitment: Explicit compatibility listings for 2004-10 A8 Quattro and 2007-09 S8 reduce guesswork when cross-referencing vehicle fit.
• OE Reference Matching: Reference numbers such as 4E0407151L and aftermarket equivalents are provided to help verify correct part selection.

Who It's For

This control arm is for owners and independent mechanics working on 2004-2010 Audi A8 Quattro or 2007-2009 Audi S8 who want a like-for-like replacement that mirrors the original suspension geometry and mounting points. It suits restorations and routine suspension repairs where a direct-fit OE replacement part is preferred over generic or adjustable arms.

Those who should look elsewhere include drivers with heavily modified suspension setups that require adjustable arms or custom geometry, and buyers who need a greasable or aftermarket performance ball joint option, since this unit is non-greaseable and not adjustable.
