AUTOACER Ball Joint Kit 2 piece - Front Lower Control Arm Ball Joints Left & Right for Expedition 2007-2014, F-150 2009-2014, Navigator 2007-2014, OEM# EL1Z3079A, EL3Z3079A, EL1Z3078A, EL3Z3078A

The AUTOACER Ball Joint Kit includes two pieces specifically designed for the front lower control arms of select vehicles. It is compatible with the 2007 to 2014 Expedition, the 2009 to 2014 F-150, and the 2007 to 2014 Navigator. This kit serves as a direct replacement and is intended to help restore the original suspension performance and handling of these vehicles without the need for complete control arm replacement. Each component in this kit is constructed using a durable combination of aluminum, steel, and rubber. The use of these materials supports the part’s ability to withstand everyday road impacts and driving conditions. The components are greasable, sealed, and designed to be installed without any drilling, offering an efficient solution for routine suspension maintenance. The grey finish gives the parts a clean, standard look suitable for undercarriage installations. Over time, rubber bushings and ball joints in the control arms may crack, wear out, or degrade, which can negatively impact the vehicle's ride quality and handling. This kit allows for the removal of worn ball joints and the installation of new ones while retaining the original control arms. It provides a solution for vehicle owners who prefer to replace only the necessary suspension parts instead of replacing the full control arm assembly. The ball joints are engineered to press directly into the original control arms using proper tools, helping to save time and reduce overall repair costs. For accurate fitment, this kit supports several OE and OEM part numbers, including EL1Z3079A, EL3Z3079A, EL1Z3078A, EL3Z3078A, EL1Z-3078-A, EL1Z-3079-A, 7L1Z3050B, 9L3Z3050A, and K500008. These part references ensure compatibility with factory specifications and assist in verifying the correct match for the vehicle model and year. The fitment type is direct replacement, making the installation straightforward for professionals familiar with suspension repair. It is highly recommended that this kit be installed by a professional mechanic, as pressing in and removing ball joints requires specialized tools to ensure correct alignment and secure fitment. Improper installation can lead to premature wear or damage to the suspension components. Additionally, once installation is complete, a professional wheel alignment is required. This step is essential to restore proper suspension geometry, prevent uneven tire wear, and ensure smooth and predictable vehicle handling. The AUTOACER 2-piece ball joint kit is engineered to meet OEM quality standards and is backed by a 2-year manufacturer’s warranty. AUTOACER, an American company, offers reliable support and stands behind the quality and consistency of its suspension components. This kit is prepared for vehicle owners who are focused on maintaining their vehicle’s original ride feel while extending the life of the factory-installed components. Proper packaging and care are taken to ensure the parts arrive in ready-to-install condition. By replacing only the ball joints and retaining the original control arms, this kit supports an efficient and cost-effective approach to front suspension repair. It is intended for use in routine maintenance or during more extensive suspension service where restoring original vehicle performance is the goal.
