Installation
1. NOTE: Lubricate the drive pinion seal lips with axle lubricant.
NOTE: Drive pinion seal must be fully seated all the way around or drive pinion seal damage will occur.
Using the Drive Pinion Oil Seal Installer, install the drive pinion seal.
2. NOTICE: Never use a hammer or install the pinion flange with power tools.
NOTE: Lubricate the pinion flange splines with axle lubricant.
Align the index marks made during removal and, using the Drive Pinion Flange Installer, install the pinion flange.
3. NOTICE: The color on the rear face of the drive pinion nut is critical to this repair. Use the same color new drive pinion nut for
installation as the original. If a new collapsible spacer must be installed for pinion bearing preload reduction, install the nut supplied with
the new spacer or damage to the component may occur.
Select the correct pinion nut for installation.
