NOTE:

If runout is within specification, install a new differential ring gear and 
pinion. If runout exceeds the maximum specification shown, the 
differential ring gear is true and the concern is due to either a damaged 
differential case or differential bearings. Inspect the differential bearings. If 
the differential bearings are not damaged, install both the differential case 
and the differential bearings new.
