    A slide hammer works. I used one that removes axle bearings. However, only 1 finger (lip) would fit in there. I also drilled (yikes, I know) with a large drill bit a little to weaken the surrrounding metal. Also make sure that you soak it with penetrating oil.
    It took me an hour with a silde hammer to get it out. I'm a big guy and I gave it eveything I had to get it out.

    Hope it helps,
    John

    Find some kind of dowel or cylindrical rod that is the same diameter as the hole in the pilot bearing. Next, pack grease into the pilot bearing hole, then insert the dowel and hammer it in. The grease will hydrolic the bearing out from behind. Hope that helps.

    Yeah, it's a good idea to wrap a rag around it before you go smacking the rod with the BFH. [​IMG]

    if it is a BUSHING the grease hydraulicing it out will work, a roller bearing wont do it. SNAP-ON makes a special puller attachment for a slide hammer for that exact dilemma. the snap guy didnt have one on his truck when i needed it so we had to improvise and break a few of the wrong ones.

    If it is a bushing, you can hit it with a air hammer and it will shatter it.

    try the "dent puller" method. screw in a BF screw in there and yank it out. I've never tried it but sure it will work.

    I had a problem pulling the bushing from my 'vette. Found a big old tap that fit inside the bushing. Cut threads through the bushing, then used the correct size bolt and cranked it 'til the bushing backed out. Worked slick!

    Real trucks don't have spark plugs!
