23. Install the differential case without the ring gear.
(1) Position the differential case, including the differential bearing shims.
(2) Position the differential bearing caps
(3) Install the bolts.
24. Position Dial Indicator/Magnetic Base.
(1) Rotate the differential case to ensure the differential bearings are properly seated.

25. Measure the differential case runout.
(1) Rotate the differential case.
(2) Measure and record 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.
-
Specification shown is the maximum differential case runout allowable.
