You can rent the slide hammer & attachment from autozone, as well you can buy the pilot bearing there too.
But before you take the old one out, look carefully inside the bearing walls. There are two opposing groves in the back of the pilot bearing. These grooves are where you want the attachment arms to be "hooked" upon.
You will be able to see them very clearly on the new pilot bearing.
I didn't look to hard for any grooves, and I ended up banging away at it until it came out in pieces (1hour later BTW).
The grooves on my old pilot bearing were at 3 o'clock and 9 o'clock almost exactly. Depending on where the motor was when you last stopped it, the alignment will be slightly different (pilot bearing is pressed into the crank).
Have someone hold a light directly into the P.B. That should help reveal the grooves.
Sorry so long. This problem made my car sit for another day, so I thought I would save you the trouble.
