Depth Gauge Check

If any of the gauge surfaces become nicked, the high spots should be removed using an oil stone.
1. Install a new rear pinion bearing over a suitable aligning adapter, then position into the pinion bearing retainer assembly.
2. Place front of pinion bearing into the bearing cup, then assemble the handle onto the screw and hand tighten. The square drive in the handle of the tool is to be used for obtaining the proper pinion bearing preload. Set preload to 20---40 inch lbs.
3. Center suitable gauge tube into the differential bearing bore, then install the differential bearing caps.
4. Using a feeler gauge tool or shims, select the thickest shim that will enter between the gauge tube and gauge block. Insert feeler gauge directly along the gauge block to ensure a correct reading. If the service pinion gear is marked with a plus (+) reading, this amount should be subtracted from the thickness dimension obtained in step 4. If the service pinion gear is marked with a minus (-) - ) reading, this amount should be added to the thickness dimension obtained in step 4.
5. Remove inner pinion bearing cup and install the correct number of shims in the carrier bore.
6. Install bearing cup and oil slinger, if equipped, on the pinion, then press on bearing using a suitable tool. If a baffle or slinger is used, replace with a new one during assembly.
