Application Procedure
- Apply a light coating of gear marking compound GM P/N 1052351 (Canadian P/N 10953497), or the equivalent, to the ring gear teeth not making contact with the pinion gear.
- Insert a standard drift punch between the ring gear and the differential carrier to bind the ring gear and create a drag.
- Slowly and evenly turn the pinion gear in the drive direction until the ring gear has made one complete revolution. Because of the drag simulated in the ring gear, this will produce a contact pattern on the drive side of the ring gear (pinion gear driving ring gear).
- Turn the pinion gear in the opposite direction with a drag simulated on the ring gear to produce a contact pattern on the coast side of the ring gear (ring gear driving pinion gear).
IMPORTANT:
In order to ensure an accurate contact pattern, make sure the ring gear turns one revolution only.
