12. NOTE: If runout is within specification, install a new ring gear and pinion. If runout exceeds specification, the ring gear is true and the concern is

install a new differential case and the differential bearings.
Measure the differential case runout without the ring gear.
1
Rotate the differential case.
2
Check and note the differential case runout.
13. Using the special tools, remove the differential case from the rear axle housing, and remove the differential bearings.
14. Using the special tool, install the new differential bearings on the differential case.
15. Measure the differential case runout without the ring gear.

Check the case runout again with the new differential bearings. If the runout is now within the specification shown, use the new differential
bearings for assembly. If the runout is still excessive, a new differential case must be installed.
