How do I get pilot bushing out?

What you need is a pilot bushing puller.

basically a slide hammer with some jaws on the end.

there are other variation pullers aswell,some have a threaded rod that you can crank down with a ratchet to extract it rather than relying on your muscles like with a slide hammer.

I have had some pilot bushing come out really easy...BUT I have also had some that were an F'ing pain to get out.

you can go to your local parts store and pick the puller up new for probably $15-$25 or you can get the rentable puller kit and you just have to pay the deposit on it and when you are done using the tool you return it and get your money back.

Here is a link with a picture of the tool http://ecx.images-amazon.com/images/I/21GtRfbIHpL._SL500_AA300_.jpg
