1. Coat the new rear axle drive pinion seal lips with grease.
2. NOTE: Installation without the correct tool can result in early seal failure.
NOTE: If the rear axle drive pinion seal becomes misaligned during installation, remove the seal and install a new seal.
Using the Drive Pinion Oil Seal Installer, install the rear axle drive pinion seal.
3. Lubricate the pinion flange splines with rear axle lubricant.
4. NOTE: Disregard the index marks if installing a new pinion flange.

6. Install the new washer and pinion nut. Only hand-tighten the pinion nut at this time.
7. NOTICE: Do not loosen the pinion nut to reduce drive pinion bearing preload. Install a new drive pinion collapsible spacer and pinion

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.
