Posted by Busadave9> Remove the oil pan. Remove the rear main bearing. You have a 2 piece seal. The piece in the main bearing you removed is easy to replace. The top half is tight on top of the crank shaft. To make it easier to remove loosen up the other bearing caps. No need to completely remove the caps. Then you can press one side of the seal out. Once you have enough out that you can grab it with a pair of pliers you should be able to pull it out. Then push the new seal back in by putting it under the crankshaft and pushing it in.
