    Drive pinion bearing preload torque:

    Refer to Inspection and Adjustment .
    CAUTION:
    • Do not reuse drive pinion lock nut.
    • Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut.
    • Adjust the drive pinion lock nut tightening torque to the lower limit first. Do not exceed the drive pinion lock nut specified torque. Refer to Disassembly and Assembly .
    • If the drive pinion bearing preload torque exceeds the specified value, replace collapsible spacer and tighten it again to adjust. Do not loosen drive pinion lock nut to adjust the drive pinion bearing preload torque.
    • After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rotation malfunction, and other malfunctions.
  11. Check companion flange runout.
  12. Install the differential case assembly.

Differential Case Assembly
