Removal Procedure
Important: If you remove or replace the ring and pinion gear set, perform the differential side bearing preload, backlash, and gear tooth contact
pattern check in order to ensure proper contact of the gears. If you reinstall or replace the differential assembly without replacing any other component
(i.e. pinion and ring gear set, differential bearings. etc.) then you may reinstall the differential assembly with the original shims in their original
locations. Always perform a gear tooth contact pattern check, even when you remove only the differential assembly.
