    • If the runout does not exceed the specification, install a new ring gear and pinion. Use the General Equipment: Dial Indicator

    • If runout exceeds the specification, the ring gear is true and the condition is due to differential carrier/differential bearing damage.

    • Inspect the differential bearings and the differential carrier. Always install new differential bearings when installing a new differential carrier, or if a bearing condition is questionable.
