3. Remove the drive shaft(s) (see Chapter Clutch and drive shafts).
4. Using a pry bar or large flat-head screwdriver, pry the old seal out of its seat in the transmission housing
5. If you cannot remove the seal with a crowbar or screwdriver, you should use a special puller (ask in car accessory stores).
6. Using a socket head of the appropriate size or a section of pipe of the appropriate diameter as a mandrel, seat the new seal in its regular place. Make sure that the seal is seated in the socket strictly perpendicularly and to the full depth. Lubricate the seal lips with transmission oil.
Note: The mandrel should only rest against the hard outer edge of the end face of the seal.
7. Reinstall the drive shaft(s), being careful not to damage the lips of the new seal(s).
