The Loaded Steering Knuckles, Nos. 686-448 and 686-449, from Dorman Products are designed to help technicians fix a worn steering knuckle without a hydraulic press or purchasing multiple components. The loaded knuckles include a new knuckle, wheel bearing, hub, and application-specific hardware that's already assembled for easier installation. These steering knuckles are specifically for front-right and front-left knuckles on the Ram 1500 2012-2018 and Ram 1500 Classic 2019-2022 trucks.
