NOTE: Rotational torque of the drive pinion flange must be measured and recorded using a Nm (lb-in) torque wrench for correct pinion bearing preload when reassembled. This will be the torque-to-turn measurement.
Using a dial type torque wrench, measure and record the rotational torque of the drive pinion.
- Using the special tool to hold the pinion flange, remove and discard the pinion nut. Use Special Service Tool: 205-126 (T78P-4851-A) Holding Fixture, Drive Pinion Flange.
