    7. CAUTION: Do not under any circumstance loosen the pinion nut to reduce drive pinion bearing preload. If it is necessary to reduce drive pinion bearing preload, install a new differential drive pinion collapsible spacer and pinion nut.
  7. Tighten the pinion nut to set the drive pinion bearing preload.
    • Rotate the drive pinion gear occasionally to make sure the drive pinion bearings seat correctly. Take frequent drive pinion bearing preload readings by rotating the drive pinion gear with a Nm (lb-in) torque wrench.
    • Refer to the TORQUE SPECIFICATION  for used pinion bearings.
