Differential Drive Pinion Gear Yoke- Runout Measurement

^ Tools Required:
- J 35819 Runout Gage
- J 35819-100 Runout Gage Adapter Sleeves
- J 8001 Dial Indicator Set

1. Raise the vehicle on a twin post hoist so that vehicle is supported on the rear axle housing and rear wheels are free to rotate.
2. Remove propeller shaft. Refer to "PROPELLER SHAFT REPLACEMENT."
3. Measure pinion gear yoke runout using J 35819, J 35819-100 and J 8001. Record runout and mark high and low points of pinion gear yoke.
4. If pinion gear yoke runout is 0.15 mm (0.006 inch) or less, remove the pinion gear yoke balance weight, if used. No further action is required.
5. If pinion gear yoke runout is greater than 0.15 mm (0.006 inch), but less than 0.28 mm (0.011 inch) and the balance weight is at or near the low point of pinion gear yoke runout, no further action is required. If balance weight is not at or near the low point of pinion gear yoke runout, remove the weight.
6. If pinion gear runout is over 0.28 mm (0.011 inch), but no greater than 0.38 mm (0.015 inch) and the balance weight is at or near the low point of pinion gear yoke runout no further action is required.
7. If the balance weight is not at or near the low point of pinion gear runout, remove the weight and rotate the pinion gear yoke until runout is 0.25 mm (0.010 inch) or less.
8. If impossible to achieve 0.25 mm (0.010 inch) or less runout, install a new differential pinion gear yoke and recheck for 0.25 mm (0.010 inch) or less runout.
^ Service replacement differential pinion gear yokes may be equipped with balance weights. These weights should not be removed.
9. Install propeller shaft. Refer to "PROPELLER SHAFT REPLACEMENT."
10. Lower vehicle.
