actually, i can get the pilot bearing for like $4. some pilot bearing pullers do fit inside. then you use a slide hammer. usually, you have to take the arms off the puller. get them both inside the bearing, then put them back on the puller. another trick is to find a bolt that fits the hole tight, then take some paper towels. get them wet and ring them out. pack as many as ya can in the hole. then use the bolt and smack it with a hammer to compact them, then remove and pack more and repeat. it will slowly hydraulic it out without the mess of tryin to pack grease in there.
