NOTE:
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.
NOTE:
This operation disturbs the pinion bearing preload. Carefully reset the pinion bearing preload during assembly.
