A Rear Axle Drive Spacer is installed between the rear axle pinion bearing and the differential carrier. It is made of steel and provides a precise preload on the pinion bearing. This preload helps to reduce friction and wear, and it also helps to ensure that the pinion gear and ring gear mesh correctly.Attributes: • Maintain proper alignment of the pinion gear and ring gear• Helps to protect the pinion bearing from dirt and debrisApplications:A Rear Axle Drive Spacer is used to space the pinion gear at the correct distance from the ring gear to ensure that the gears mesh correctly and that the power is transferred efficiently.
