  Q: What tools are required to service and repair the differential for final drive replacement (M15) on Buick Terraza?

  A: Service technicians need Axle Removal Wedge (J 42562) and Transjel Lubricant (J 36850) to replace final drive units during differential servicing (M15). Two tools needed for differential service and repair include Axle Removal Wedge (J 42562) and Transjel Lubricant (J 36850). First secure case extension housing out of the way then turn differential carrier through a full 360° until you can see output shaft end while differential pinion shaft (701) becomes horizontal. Use the Axle Removal Wedge (J 42562) between the output shaft end and differential pinion shaft. Strike the tool end with a hammer to compress the output shaft compression ring (512) so the output shaft passes through the differential side gear. After taking out the differential carrier (700) install snap ring pliers to remove the output shaft compression ring (509). Start by extracting the stuck sun gear thrust bearing (698) from the differential carrier sun gear and continue with the differential carrier sun gear (697) and park gear (696) and internal gear thrust bearing (695). Check the sun gear shaft (689) for damage after its complete removal. Put together the sun gear thrust bearing (698) and differential carrier sun gear (697) with park gear (696) and internal gear thrust bearing (695) and sun gear shaft (689) for the differential carrier (700) before installing the differential.
