- Drain the differential carrier assembly of axle lubricant, if necessary. Refer to Lubricant Replacement - Front Drive Axle .
- Wipe clean the ring gear of axle lubricant. Carefully clean each tooth of the ring gear.
- Use a medium stiff brush in order to sparingly apply gear marking compound, GM P/N 1052351or equivalent, to all of the ring gear teeth.
- Apply a turning torque load of 14 N.m (10 lb ft) to the differential case and the drive pinion.
- Using a wrench, turn the drive pinion flange/yoke so that the ring gear rotates at least 3 full revolutions.
- Turn the drive pinion flange/yoke in the opposite direction so that the ring gear rotates at least 3 full revolutions in the opposite direction.
