Oil Seal - Pinion Flange, Renew
- Disconnect vehicle battery ground lead.
- Support the vehicle at the rear.
- Disconnect main handbrake cable at compensator.
- 'Match mark' the FLEXIBLE COUPLING to the differential DRIVE FLANGE and remove fixings.
- Remove fixings center bearing to crossmember and push drive shaft rear section forward to disengage from pinion spigot.
CAUTION: Under no circumstances must the flexible coupling (or its fixings) be loosened or removed from the drive shaft flange.
- Support the drive shaft, do not allow it to hang.

- 'Match mark' the drive flange retaining nut to both the pinion and the drive flange (Fig.1).
- Slacken the flange retaining nut approximately half a turn and retighten to the 'match mark' noting the required force. If the force does NOT exceed
135 Nm, the final drive unit MUST be replaced.
- Remove the retaining nut, washer and drive flange.
CAUTION: Use only special tools; 18G 1205 to restrict rotation and JD 156 to remove drive flange.
- Inspect the drive flange oil seal surface for damage corrosion or grooving and replace as necessary.
Note: Do not use abrasive cloth, or paper, to remove imperfections from the seal surface.
- Remove oil seal from differential case taking care not to damage the machined counterbore.
- Clean seal counterbore.
- Using special tool JD 18G 1428A fit replacement oil seal to differential case ensuring that, seal is square, fully seated and the lip spring is not
dislodged.
- Apply grease to drive flange seal diameter and refit the flange to the pinion in the original position.
Note: Do not hammer the drive flange onto the pinion; pull down with the drive flange nut.
- Tighten the drive flange nut to the original noted torque PLUS 10%.
- Check that the pinion spigot radial run-out is to specification.
- Fitting and reassembly is the reversal of this procedure ensuring that drive shaft fixings are renewed and that the shaft is aligned.
- Correct the final drive oil level if required.
- Tighten all fixings to specification.
