The Mevotech GS40155 Rear Right Lower Control Arm and Ball Joint Assembly is engineered to restore original equipment (OE) performance, handling, and ride quality in vehicles such as the 2009-2012 Ford Escape and Mercury Mariner. This assembly is designed to address common suspension issues, including uneven steering, squeaking noises, and excessive tire wear, thereby enhancing vehicle stability and alignment. By providing a firm connection between the vehicle's frame and wheel, it effectively reduces transmitted noise, road shock, and vibration, contributing to a smoother driving experience. The assembly features a corrosion-resistant finish and is pre-greased for immediate installation, ensuring durability and longevity. Its design includes thicker forgings to minimize excessive flexing and twisting of the suspension system, thereby improving overall performance. The Mevotech GS40155 is a direct OE replacement, facilitating a straightforward installation process and restoring the vehicle's original suspension specifications.
