Seal, Drive Pinion: Removal
- Remove the rear axle assembly from vehicle. Refer to REMOVAL .NOTE:
Torque reading must be taken with a constant rotational speed. Do not measure break away torque.
- Using a torque wrench (1), measure and record the pinion rotational torque.NOTE:
Due to axle imbalance concerns and bearing preload sensitivity, it is necessary to make sure pinion nut-to-shaft orientation is maintained. If alignment marks are not visible, apply appropriate marks before removing pinion nut.
- Apply an alignment mark (2) on the pinion flange nut (1) to the pinion shaft (3) and the pinion flange (4).
- Using Flange Wrench (special tool #C-3281, Holder, Flange) (1) and 32mm socket, remove the pinion flange nut.NOTE:
Due to axle imbalance concerns and bearing preload sensitivity, it is necessary to make sure pinion flange-to-shaft orientation is maintained. If alignment marks are not visible, apply appropriate marks before removing pinion flange.
- Apply an alignment mark (3) on the pinion flange (1) to the pinion shaft (2) and should be aligned after nut has been removed.
- Using Puller (special tool #1026, Puller), remove pinion flange from pinion shaft.
- Using seal remover (special tool #7794-A, Remover, Seal) (1) and slide hammer (special tool #C-637, Slide Hammer, Universal), remove the pinion seal and discard.
