Differential Case Assemble

Tools Required

• 87-92-210  Differential Bearing Support. See Special Tools and Equipment .
• SA9120T  Differential Bearing Installer. See Special Tools and Equipment .
• SA9172G  Ball Detent Handle. See Special Tools and Equipment .

1. Assemble the differential gear assembly by installing the differential case (320) to ring gear (307) using 12 ring gear to case bolts (306).

   Tighten:  Tighten the ring gear to case bolts to 20 N.m (15 lb ft) plus 90 degrees.

   An option for limited slip differential or open differential exists for some models. See inset. Both differential assemblies are serviced only as a complete assembly. The bolts, ring gear and tapered roller bearings are serviceable components.
