12. Measure the differential case runout without the ring gear.
1. Rotate the differential case.
2. Check and note the differential case runout.
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 due to either a damaged differential case or differential bearings. Inspect the differential bearings. If the differential bearings are not
damaged, replace both the differential case and the differential bearings.
13. Remove the differential case from the rear axle housing and remove the differential bearings using the 2-Jaw Puller for Differential Case Bearings
and the Step Plate Adapter.
14. Use Differential Side Bearing Replacer to install the new differential bearings on the differential case.
