- Tighten the nut.
- Use the special tool to prevent the flange from turning while tightening the nut. Remove the special tool when taking pinion bearing torque preload readings.
- Take frequent pinion bearing torque preload readings.
- The final reading must be 0.56 N.m (5 lb-in) more than the initial reading taken during removal.
- Connect the front driveshaft to the front axle flange.
- Remove the tape from the bearing cups.
- Connect the front driveshaft to the front axle flange.
- Install the 2 new retainers and 4 new bolts.

Never back off the pinion nut to reduce preload. If preload reduction is necessary, install a new collapsible spacer and pinion nut.
NOTE:
Align the index-marks on the front driveshaft and the front axle flange to maintain driveline balance.
