In this review the reviewer looks at the Metrix front left lower rearward control arm with ball joint and bushing assembly and finds it suited for owners who need a reliable suspension replacement. The bottom line is that this part delivers solid fit and function for compatible Mazda, Ford, Lincoln and Mercury models while offering pre-greased convenience and an extended warranty. For someone replacing a worn control arm, the main reason to buy is the combination of build quality and certification that exceeds OEM standards.
Key Features
- Vehicle compatibility: Direct fit for many 2003-2012 Mazda, Ford, Lincoln and Mercury applications, reducing the need for modification during installation.
- Pre-greased joint: Comes pre-greased so the ball joint and bushing start life ready to move smoothly and resist wear from the first mile.
- Steel construction: Built from steel to provide the stiffness required for suspension control and long term durability under normal driving conditions.
- Exceeds OEM standards: Manufactured to IATF 16949 and ISO 9001 quality systems, indicating tighter quality control than typical aftermarket parts.
- Warranty backing: Includes a 3 Year / 36,000 mile limited warranty from installation date, offering added peace of mind for replacement jobs.
Who It's For
This part is aimed at DIY enthusiasts, home garage mechanics, and independent shops replacing a failed front left lower rearward control arm on compatible 2003-2012 vehicles from Mazda, Ford, Lincoln and Mercury. It is a good choice when an OE-equivalent replacement is needed without paying dealer pricing, especially where pre-greased components save a step during installation.
Customers who require a universal or performance-tuned control arm, or who need parts outside the listed application years, should look elsewhere. Also, anyone needing a full set of chassis components for custom suspension geometry should consider a matched kit rather than this single-arm replacement.
Pros & Cons
Pros
- Fit and compatibility are consistently reported as accurate, making installation straightforward.
- Pre-greased ball joint and bushing reduce initial maintenance and help ensure smooth operation.
- Quality control certifications and steel construction promise a durable, reliable replacement part.
Cons
- Sold as a single arm, so replacement of both sides requires purchasing multiple units.
- Does not substitute for performance or adjustable control arms used in modified suspension setups.
