Differential Case End Play Check

1. Install the appropriate Dummy Differential Bearing from the Master Bearing Set.
2. Remove all nicks, burrs, dirt, etc., from the rear hubs, to allow the bearings to rotate freely.





3. Install the outboard differential selective spacers into the rear axle differential carrier. Assemble the differential case into the rear axle differential carrier (less pinion).





4. Mount the Dial Indicator/Magnetic Base or Dial Indicator with Bracketry as shown. Locate the tip of the indicator with the Clutch Housing Alignment Adapter on a flat surface of one of the ring gear screw spot faces.

NOTE:
- The Dial Indicator should have a minimum travel capability of 5.08 mm (0.200 inch).
- The rear axles use a combination of hard inboard spacers and selective outboard shims. The old outboard selective shims can be used as a starting point. If additional shimming is required other than what can be obtained with the hardened inboard spacers, a new outboard selective shim must be used.





5. Force the differential case as far as possible toward the indicator. With force still applied, set indicator at 0.

NOTE: Repeat Steps 5-7 until you have obtained the same reading each time. Record the reading of the indicator. This is the total amount of differential bearing shims required (less preload) and will be calculated later during assembly.





6. Force the differential as far as it will go opposite direction.
7. After making sure the readings are correct, remove the indicator and the differential from the rear axle housing. Do not remove the master bearings from the differential case at this time.
8. This reading is the total differential case end play, which will be needed for assembly of Differential into Housing.
