6. While lifting the rear differential in place, align the pilot shaft (1) and the pilot hole (2).
Note: Hand start the rear differential mounting bolt.
7. Install the left (1) and right (2) rear differential mounting bolts and tighten to 175 Nm (129 lb ft).
8. Apply GM threadlocker to the NEW differential carrier bracket bolts (1). Refer to Adhesives, Fluids, Lubricants, and Sealers ([1][2]Drive/Propeller Shaft).
Note: Use only hands tools to tighten the bolts.
