Drain approximately one liter of fluid from the differential, then remove the driveaxle. Push the wheel seal into the differential as far as it will go and measure the distance between the transaxle case and the wheel seal to ensure proper reassembly. Use a slide hammer to drive out the wheel seal, and employ a two-jaw puller and slide hammer to remove the old seal from the bore in the differential; if these tools are unavailable, a large screwdriver can be used with caution to avoid damaging the seal bore. Drive in a new seal with a large socket slightly smaller than the outside diameter of the seal and coat the lip of the new seal with multipurpose grease. Install a new snap ring into the groove of the wheel seal and carefully tap the wheel seal into the differential with a plastic or rubber mallet until it contacts the pinion shaft, indicated by a change in sound. Measure wheel seal end play using a dial gauge by pushing the seal all the way into the differential, zeroing the gauge against the face of the wheel seal flange, and pulling the seal out until it binds, ensuring there is 2 to 3 mm (0.08 to 0.12 in) of end play. Verify that the wheel seal will not come out by pulling hard on the flange, then push the wheel seal all the way into the differential and measure the distance between the wheel seal and the transaxle case, comparing it with the previous measurement to confirm they are the same. Finally, install the driveaxle and fill the differential with ATF Dexron II fluid to the specified level.

The first step is to remove the drive axle.
