Subaru Stars Meatys guide to replacing rear main seal

1. Remove engine or transmission

2. Use 1 to 3 drywall screws and drive them into seal with a drill about 1/2" or so

3. Using a prybar (could probably use a claw hammer as well), pry up on the screws. Sometimes the whole seal will pop out with 1 screw, if not, pry on all screws a bit at a time.

4. Clean crank surface and inside of sealed area with a shop towel

5. Fill inner groove of new rear main seal with a lithium grease / assembly lube

6. Hold seal against crank and keep it aligned with your hand while driving it in with a plastic-tip hammer. As soon as it starts to go on a bit, tap the opposite sides in a criss-cross pattern to keep it going on evenly. Drive the seal to where it is even with the block surface.

I thought flathead screwdrive and hammer worked just fine

And the factory seal didn't have any grease packed into it...

Great method. Nice and simple BUT... BE REAL CAREFUL YOU PLACE THE SCREWS SLIGHTLY TOWARD THE CASE SIDE OF THE SEAL. If you place the screw toward the crank side of the seal, and the screw contacts the surface of the crank, you run the risk of scoring the crank as you pull the seal out.

This can result in about 30 min of careful work with emery paper...

I just used a flat screen driver and pry it bit by bit and then digged into the ringand popped it out. For installation, I used the old seal and placed above the new one and use a hammer to tap it in. Without something holding it on one side while hammering the opposite side, it will tend to pop out from the side that is not being hammered. It's a pain. And then with the old seal on top, just slight hit each side and then check if it's flushed. Becareful not to hit it too hard, or the flat ring surface will be bent since it's made out of metal.
