  5. Using the special tool to hold the pinion flange, tighten the pinion nut.
    • Rotate the pinion occasionally to make sure the cone and roller bearings are seating correctly.
    • Install a Nm (inch-pound) torque wrench on the pinion nut.
    • Rotating the pinion through several revolutions, take frequent cone and roller bearing torque preload readings until the original recorded preload reading is obtained.
    • If the original recorded preload is lower than specifications, tighten to the appropriate specifications for used bearings. If the preload is higher than specification, tighten the nut to the original reading as recorded. For additional information, refer to TORQUE SPECIFICATIONS .
  6. Position the rear driveshaft and align the marks on the pinion flange.
