For this procedure the transaxle has to be unbolted from the car and supporting from above is the engine hoist or the three bar support when you will be working under the car with the transaxle out. First, using seal removal tool or screw driver gently try to remove the old Crankshaft Seal from the retainer touching the crankshaft it's that sensitive maybe maybe because of that the new seal will develop a leakage. Next, spread multi-purpose grease to the crankshaft seal journal and the sides of the new seal lip. It is preferred to employ a seal installation tool to achieve the installation of the new seal; in the absence of this implement, a large socket, pipe segment or, a blunt object must be used to gently tap the new seal into place. Make sure that lip is guided on to the seal journal of the crankshaft in a gentle and slow fashion, since this is likely to disrupt the seal. Screw the installed seal right into place but no deeper than so that the flange of the seal is in line with the back of the seal plate. The last few steps are basically those of the reversibility of the removal process outlined above.
