Remove the oil slinger/pinion depth shim from the pinion shaft. Record the thickness of the oil slinger/depth shim. Place 4 adapter blocks so they do not damage the bearing cage.
INSTALLATION NOTE: Pinion depth shims are placed between the rear pinion bearing cone and the pinion head to achieve proper ring and pinion gear mesh. If the factory installed ring and pinion gears are reused, the pinion oil slinger/depth shim should not require replacement. Refer to Pinion Gear Depth to select the proper thickness shim before installing pinion gear. (1) Apply Mopart Door Ease, or equivalent, stick lubricant to outside surface of rear pinion bearing cup. Install the bearing cup with Installer D-146 and Driver Handle C–4171 (Fig. 44). Verify cup is correctly seated.
