Hy bozer, there are two different inner bearing possibilities for your truck, depending on whether or not your truck has a heavy duty axle or not. The heavy duty axle inner bearing is a tappered roller bearing, two piece unit, Napa p/ns are BR25583 $59.40, and BR25519 $28.35. The standard axle inner bearing is a ball bearing, Napa p/n BRG B46 $129.60, hope that helps.
