The transmission must be removed from the vehicle for this procedure. Carefully pry the old Crankshaft Seal out with a seal removal tool or screwdriver, ensuring not to damage the crankshaft, as any damage may cause the new seal to leak. Apply multi-purpose grease to the crankshaft seal journal and the lip of the new Crankshaft Seal. It is preferable to use a seal installation tool to press the new seal into place, taking care to work the stiff lip onto the seal journal of the crankshaft without rushing, as this may damage the seal. Install the seal squarely and only until it is flush with the back of the seal retainer, no further. The remaining steps involve reversing the removal process.
