Reassembly (Case Assembly)

  1. Lubricate all parts with hypoid gear oil. Place pinion gears and thrust washers on differential spider. Install side gears and thrust washers to case halves in their original locations. Install differential spider to differential.
  2. Assemble case halves, aligning marks previously scribed on case. Obtain and install 2 left-hand threaded studs in ring gear, directly opposite each other to ease in alignment/installation process of ring gear.
  3. Install ring gear onto studs. Tap ring gear lightly with soft-faced hammer until new ring gear attaching bolts can be installed. Tighten bolts evenly until ring gear is flush with case flange.
  4. Remove threaded studs. Install 2 remaining bolts and tighten all ring gear bolts alternately and evenly to specification. See TORQUE SPECIFICATIONS  table. Install differential side bearings using driver handle and Bearing Installer (J-24449).
