Metrix Premium Front Upper Control Arm for 2002-2007 Jeep Liberty

In this review of the Metrix Premium front upper control arm, the bottom line is straightforward: this is a direct replacement for 2002-2007 Jeep Liberty owners who want a durable, OEM-compatible part without paying dealer prices. The reviewer found the part to be well made from cast iron, pre-greased for immediate installation, and engineered to exceed OEM standards, making it a sensible choice for someone replacing a worn or noisy upper control arm and seeking long-term reliability and a warranty-backed option.

Key Features

• Vehicle compatibility: Fits 2002-2007 Jeep Liberty models, which makes it a simple swap for owners of those model years.
• Pre-greased assembly: Supplied pre-greased so the ball joint and bushing move smoothly right away and reduce initial break-in noise.
• Cast iron construction: The cast iron material provides strength and resistance to flex under load for stable steering feel.
• OE interchange numbers: Cross-references RK3198, CMK3198, 520-354, 52088632AA to help verify fitment against original parts lists.
• Quality standards: Manufactured to IATF 16949 and ISO 9001 processes, which indicates consistent production and quality control above basic aftermarket parts.
• Warranty support: Backed by a 3 year / 36,000 miles limited warranty, giving added confidence after installation.

Who It's For

This control arm is aimed at Jeep Liberty owners who need a straightforward replacement that mirrors OEM fit and function. It suits do-it-yourself mechanics and independent shops that value parts with documented interchange numbers and factory-style construction.

Drivers who want a lifetime-branded, expensive performance upgrade or a lightweight racing component should look elsewhere; this part emphasizes durability and OEM equivalence rather than weight savings or specialty tuning.

Pros & Cons

Pros

• Good fit for listed model years, with customers reporting an accurate match and elimination of knocking noises.

• 3 year / 36,000 miles limited warranty gives practical protection after installation.

Cons
