Pinion Flange Runout Check

CAUTION: Pinion bearing preload must be reset if the pinion nut has been loosened or removed for pinion flange reindexing or new component installation.

1. Raise and support the vehicle.
2. Remove the driveshaft.
3. Check the Pinion flange for damage.





4. Check the runout using the special tool. Rotate the pinion until the runout is obtained. If the runout is still more than 0.0762 mm (0.003 inch), install a new gearset.
5. If excessive runout is still evident after installation of a new pinion flange, install a new ring and pinion. Repeat the above checks until the runout is within specifications.
6. Install the driveshaft.
