The easiest way is to:
Step 1. Procure a Chilton's or Haynes manual for your car.
Step 2. Locate and follow the procedure therein.
It is a fairly simple procedure to R&R the front seal.
You can take the front timing cover off of the car, but with care and a bit of ingenuity you may be able to save some time and effort by carefully drilling some small holes in the metal part of the seal, thread in some screws and use them to pull the seal with the cover on the car. Usually one or two screws will suffice. Make sure you get the metal particles out of the cover. You can put some grease into the drill bit spirals and drill slowly to reduce the chance of chips getting into the oil pan.
I use a pair of vise grips that I replaced the adjustment screw with a piece of threaded rod. Then put a large socket or other weight with a hole in the center over the threaded rod and cap off the end of the rod with a washer and nut. This makes a redneck/shade tree slide hammer that will allow you to grip the screw heads and pop the seal out easily.
To replace it, find a large socket or piece of pipe that closely matches the O.D. of the seal and will fit over the crankshaft snout and use that to gently and carefully tap the seal back into place.
Remember to take care and remove any metal particles and be sure to lube the inside of the seal before installing.
If you elect to remove the front cover, don't forget to drain the antifreeze out first and be careful to not let anything fall into the oil pan.
