the outer bearings can be driven in using a suitable Very Large socket. Removing the old ones either requires a puller or a cutting torch. I use either depending on the state of the bearings.
when driving new ones in, make sure

1. your socket wont jam in with the bearing
2. you only hit against the outer bearing shell
3. you keep it very straight
4. hit it til you hear a resounding solid clunk as the bearing reaches full insertion.
5. you fit a new oil seal
6. use a block of wood across the oil seal face to protect it as you knock it in - keep it straight!

Hello, it's not "easy" but, it's doable.
You'll need to follow the instructions and don't take shortcuts. ask for help if you need it.
Use this link to get an idea of what is involved. Ignore the "remove transmission" part. It can be done without removing the tranny. If you decide to do this buy a service manual to help you. If you have any questions feel free to ask.

Replacement is pretty difficult, but if you go to advance auto parts, (cheap trick) you can buy "rear main seal repair" it works. I used it on my dodge dakota, and the leak only persisted for about a week, and was fine after that. Worth a shot, a new seal is very hard to install. You have to basically pull the entire motor up and out to reach it for one, then, setting the seal is just a pain.

i had the same problem and it turned out to be the gasket on the rear main seal housing not the rear main seal.
