MOOG Front Left Lower Control Arm with Integrated Ball Joint for Subaru Forester 2014–2018 — Ready-to-Install

MOOG RK622857 is a ready-to-install front left lower control arm with an integrated ball joint engineered to restore proper suspension geometry and steering response on 2014–2018 Subaru Forester models.

If your Forester shows uneven tire wear, loose steering feel, or clunks from the front suspension, replacing the lower control arm with a factory-fit assembly can quickly return stability and alignment. MOOG designs these assemblies for strength, corrosion resistance, and long-life performance, delivering a bolt-on replacement that eliminates the need to press in a separate ball joint.

How does this control arm help steering and alignment?

The control arm locates the wheel hub relative to the chassis, so a precise replacement maintains correct caster, camber, and toe settings. Using a complete arm with a pre-installed ball joint minimizes play in the suspension and reduces the chance of premature tire wear.

• Restores suspension geometry to factory specifications for predictable steering.
• Pre-installed ball joint reduces tolerances and free play compared with separate components.
• Engineered bushings absorb road inputs while keeping the wheel aligned under load.

What makes the MOOG RK622857 durable for everyday driving?

MOOG parts are built to withstand road stresses through reinforced structures and protective finishes that resist corrosion. The assembly is manufactured and tested to meet the demands of typical commuting, hauling, and light off-road conditions faced by many Forester owners.

• Robust arm construction designed to handle repeated suspension loads.
• Corrosion-resistant coatings extend service life in wet or salty climates.
• Factory-style ball joint and bushing materials selected for durability and consistent performance.

Is installation straightforward for this replacement part?

The RK622857 ships as a complete control arm and ball joint assembly so you avoid ball-joint press work and most alignment complications. While a professional alignment is recommended after installation, the bolt-on design simplifies swap-out and reduces shop time compared with rebuilding an arm from separate components.

• Delivered as a single assembly ready for bolting into the vehicle.
• Saves labor compared with removing and pressing a separate ball joint.
• Recommended post-installation wheel alignment restores precise tracking.
