Eaton 129378 is a differential bearing cone, a genuine Eaton part from Pro Gear and Transmission. The cone is the inner race of a tapered roller bearing, and in a differential it supports the rotating assembly while it carries gear loads. When a bearing like this wears, it tends to announce itself as a rumble that follows road speed or a howl from the axle, and a loose bearing can let the gear set lose its proper alignment. Call us to confirm proper fit for your application.
