7. Rotate the pinion while tightening the nut to seat the bearings.
Caution: Refer to Fastener Caution (See: Service Precautions/Vehicle Damage Warnings/Fastener Caution) .
Note
Compare this measurement with the rotating torque recorded during removal.
8. Using an inch pound torque wrench and tightening in small increments, measure the rotating torque of the pinion until the reading is greater than
0.40-0.57 Nm (3-5 lb in) , the rotational torque noted at removal.
Note
Recheck the rotating torque and adjust if necessary.
9. Once the specified torque is obtained, rotate the pinion several times to seat the bearings.
