how to remove the pilot bushing
Autozone has a service where you can use their tools for free with a security deposit.
What you need is a "pilot bushing" removal tool...they have them.
looks like a gear puller but the claws are pointing outward, slip the tool into the hole of the bushing, tighten the tool to get the claws snug against the bushing and use the slide hammer to get it out.
Use the proper tool to put the new one in.
