56KH448 is a Mack differential pinion, sold individually. Our parts manual lists it in the Mack CRDP 95 / CRD 96 Differential, in the Gear Ratio Application Chart, as a helical pinion gear. The pinion is the small gear that takes drive from the driveshaft and turns the ring gear, redirecting the power at a right angle toward the axles. Its tooth count is normally lower than the ring gear's, which is where the reduction in the set comes from. Worn ring and pinion gears typically show up as a howl or whine under acceleration. Sold by Pro Gear and Transmission. Call us to confirm proper fit.
