I am trying to replace my bearings and grease seal on my factory rear end. The bearings are pressed in and I cannot figure out how to knock them out. Is there a special tool needed for removal?

The one you'll need will have 3 internal-expanding jaws that grip the bearing outer race from the inside. I changed a similar set of bearings on my Dodge pickup a few weeks ago by cutting a slot through the outer bearing race with a die grinder after prying the bearing rollers out.

The grease seal has a rubber lip on one side. Does the rubber lip go inside towards bearing or outside towards wheel?

The reason is any internal pressure will put additional pressure on the seal. If it was installed the other direction, any pressure would push the lip seal open allowing more fluid to escape.
Face it toward the bearing.
