Front Left Lower Control Arm for 17-19 Nissan Sentra - Pre-Greased

In this review of the Metrix Premium Chassis Parts front left lower control arm, the bottom line is simple: buyers who need a direct-fit replacement for compatible Nissan models will appreciate its build quality and ready-to-install condition. The reviewer found the part to be a practical, no-surprise swap for vehicles listed in the fitment, with the single biggest reason to buy being the pre-greased ball joint and bushing that reduce initial break-in friction and simplify installation. This review focuses on fit, materials, and warranty-backed reliability for independent installers and DIY mechanics alike.

Key Features

• Fitment: Engineered specifically to fit 2017-2019 Nissan Sentra L4 1.6L and a range of Juke and Leaf years, which reduces fitment guesswork for compatible owners.
• Pre-greased assembly: The ball joint and bushing arrive pre-greased to extend life and ensure smooth initial movement right after installation.
• Material: Constructed from steel for durability under road stresses and to match the original suspension strength.
• Quality standards: Manufactured to exceed OEM standards and produced in IATF 16949 and ISO 9001 certified facilities for consistent reliability.
• Warranty: A 3 year / 36,000 mile limited warranty from installation gives confidence against early failures.
• OE interchange: Supplied with common OE/interchange numbers such as RK621157 and 545011KA0A, making it easy to verify compatibility.

Who It's For

This control arm is aimed at owners and independent mechanics working on 2017-2019 Nissan Sentra L4 1.6L, multiple Nissan Juke model years, and 2011-2022 Nissan Leaf variants who want a straightforward replacement that meets or exceeds factory standards. It is also suited to those who prefer a part that arrives ready to install with the ball joint and bushing pre-greased, saving time during a suspension repair.

It is less appropriate for owners of non-listed makes or models, or for those seeking an upgraded performance arm made from lightweight specialty alloys; this is a heavy-duty steel replacement focused on OE-level durability and fit rather than race-oriented weight savings.

Pros & Cons

Pros

• Good fit: customers report the control arm fits perfectly with minimal adjustment required.
• Ease of installation: pre-greased joints reduce prep time and initial break-in handling issues.
• Quality and value: steel construction and certified production offer solid longevity for the price.
• Warranty-backed: the 3 year / 36,000 mile limited warranty protects against early defects.

Cons

• Not a performance upgrade: this is a direct replacement in steel, so it will not reduce weight for performance applications.
• Single quantity: sold as one control arm, so buyers replacing both sides must order two units.
