Front Left Lower Forward Control Arm with Ball Joint - Drivers Side

In this review of the Front Left Lower Forward Control Arm with Ball Joint the bottom line is straightforward: this is a direct-fit OE replacement for owners of compatible Audi A6 Quattro, A8 Quattro, S8 and VW Passat models who need a reliable, vehicle-specific lower control arm assembly. The reviewer finds it best for DIYers and independent shops because it mirrors OE fit and reference numbers, simplifies installation, and restores proper suspension geometry when the original arm or ball joint has failed.

Key Features

• Direct Fit: Designed to match original mounting points so installation is straightforward for owners who follow vehicle-specific fitment information.
• OE Replacement Assembly: Includes the control arm and ball joint as a single unit to restore correct suspension alignment and reduce installation steps.
• Vehicle Specific Compatibility: Fitment notes cover Audi A6 Quattro, A8 Quattro, S8 and certain VW Passat years, reducing the risk of ordering the wrong part.
• OE Reference Matching: Cross-references OE numbers such as 4B3407151A, 4B3407151C and 4B3407151K for confident part identification.
• Aftermarket References Provided: Multiple aftermarket reference numbers are listed to help technicians verify interchangeability with existing catalogs.

Who It's For

This control arm is aimed at owners and mechanics servicing 2000-2004 Audi A6 Quattro, 2000-2003 A8 Quattro, 2001-2003 S8 and 2003-2005 Volkswagen Passat vehicles who need a front left lower forward replacement that closely matches OE parts. It is particularly useful for those who prefer an assembled unit with the ball joint included, saving the time of separate press-fit jobs.

Shops or owners with unclear fitment should check the vehicle-specific listing details and the supplied OE reference numbers before purchase. If a vehicle is outside the listed years or VIN-specific ranges, or if only a bushing needs replacement, a different part may be a better fit.
