    7. CAUTION: Under no circumstances is the pinion nut to be backed off to reduce drive pinion bearing preload. If reduced drive pinion bearing preload is required, a new drive pinion collapsible spacer and pinion nut must be installed.
    CAUTION: Remove the special tool while taking drive pinion bearing preload readings with the Nm (lb-in) torque wrench.

  7. Using the special tool to hold the pinion flange, tighten the pinion nut.
    • Rotate the drive pinion occasionally to make sure the drive pinion bearings are seating correctly.
    • Install a Nm (lb-in) torque wrench on the pinion nut.
    • Rotating the drive pinion through several revolutions, take frequent drive pinion bearing preload readings until the original recorded drive pinion bearing preload reading is obtained.
    • If the original recorded drive pinion bearing preload is lower than specification, tighten to the appropriate specification for used drive pinion bearings. If the drive pinion bearing preload is higher than specification, tighten the pinion nut to the original reading as recorded. For additional information, refer to the SPECIFICATIONS .
  8. Position the driveshaft and align the index mark on the pinion flange.
