Note! The screw and inner socket in the extractor must be screwed out when tapping on the extractor.

Tap the tool onto the seal so that the flat end is against the seal. Tighten the inner socket. Counter hold the outer part at the same time so that the tool expands against the seal.
Remove the seals using the screw in the extractor.
Check that no seal residue is left in the final drive.
If the inner part of the seal remains in place, tap in the extractor again and pull out the inner part.

Note! Do not knock in the extractor too hard as this can damage the extractor, which in turn can scratch the contact surface on the pinion shaft.

Check that no seal residue is left in the final drive.

Installation

Installing the pinion seal




The seal consists of 2 sections but is installed as one unit.
Lubricate the lip of the seal using oil for the Active on Demand Coupling, P/N 116 1641 (1 liter pack).
Use 999 7024 Drift pinion seal Haldex coupling 999 7024 Drift Pinion Seal Haldex Coupling for installation. Position the section of the seal with the largest outer diameter against the drift. Tap in the seal until the head of the drift goes against the final drive housing.
Install the Active on Demand coupling. Fill with oil and check the level. See: Clutch four-wheel drive Clutch Four-Wheel Drive.
