    4320 White Axles built after 7/16/07
    4C121 White Kit with spacer for all 266.7 mm (10.50 in) axles
    7. CAUTION: Install a new pinion nut with the same color as the original if not replacing the collapsible spacer or damage to the component may occur.
  7. Install the new washer and pinion nut. Only hand-tighten the pinion nut at this time.
    8. CAUTION: Do not loosen the pinion nut to reduce drive pinion bearing preload. Install a new drive pinion collapsible spacer and pinion nut if drive pinion bearing preload reduction is necessary. If a new collapsible spacer must be installed for pinion bearing preload reduction, install the nut supplied with the new spacer kit or damage to the component may occur.
  8. Using the special tool to hold the pinion flange, tighten the pinion nut to set the drive pinion bearing preload.
    • Tighten the pinion nut, rotating the pinion occasionally to make sure the drive pinion bearings are seating correctly. Take frequent drive pinion bearing preload readings by rotating the drive pinion gear with a Nm (lb-in) torque wrench. The final readings must be 0.56 Nm (5 lb-in) more than the initial reading taken during removal.
  9. Install the driveshaft. For additional information, refer to DRIVESHAFT article.
  10. Install the brake calipers. For additional information, refer to REAR DISC BRAKE article.
