Front Left Lower Control Arm with Ball Joint for Touareg/Cayenne

In this review of the Metrix Premium front left lower control arm assembly, the bottom line is practical and specific: this replacement part is for owners of 2011-2018 Volkswagen Touareg, 2011-2018 Porsche Cayenne, and 2007-2015 Audi Q7 who need a durable OE-equivalent arm with pre-greased components. The review finds the assembly delivers solid build quality and straightforward fitment, with the biggest reason to buy being its factory-level standards and a reassuring 3 year / 36,000 mile limited warranty that covers installation date issues.

Key Features

• Pre-greased components: The ball joint and bushing arrive pre-greased to extend service life and reduce initial break-in noise or stiffness.
• Steel construction: Built from steel for robust torsional strength and long-term durability under highway and city driving loads.
• OE interchange numbers: Matches common OEM references RK620456, CMS70124, 521-955, 7L8407151E for easier parts matching during purchase.
• Quality standards: Manufactured to IATF 16949 and ISO 9001 processes, indicating production and quality control above basic aftermarket norms.
• Warranty support: Includes a 3 year / 36,000 miles limited warranty from installation, providing added peace of mind after replacement.

Who It's For

This control arm is aimed at DIY mechanics and independent repair shops working on late-model Volkswagen Touareg, Porsche Cayenne, or Audi Q7 SUVs that require a direct-fit front left lower control arm assembly. It suits buyers who want a part that closely follows OEM specifications and comes pre-greased to reduce initial labor for lubrication.

Those who should look elsewhere include owners of non-listed model years or different left/right suspension positions, and anyone seeking a repair that explicitly requires an OEM-branded part number not covered by the listed interchanges. Verify the vehicle application and part number before ordering to ensure proper fit.

Pros & Cons

Pros

• Direct compatibility with multiple Touareg, Cayenne and Q7 model years makes sourcing easier for these vehicles.
• Pre-greased ball joint and bushings reduce initial maintenance and help ensure smooth early operation.
• Manufactured to IATF 16949 and ISO 9001 standards, indicating reliable production quality.
• Backed by a 3 year / 36,000 mile limited warranty for installation-date coverage.

Cons

• Only one control arm is supplied in the box, so buyers needing both sides must purchase two units.
• Steel construction can be heavier than some aftermarket aluminum alternatives, which may matter in weight-sensitive tuning.
