HI, i have a 1994 geo metro xfi, and i just bought the crossed drilled rotors and new brake pads. i never taken of the brakes before. and the hub won't budge. how do i get it off with out going to autozone and renting a slide hammer.
In two words: you don't. You need the slide hammer and there's nothing you can do about it.
Make sure that you have your hub nut unstaked and removed first, or else you'll just be hammering away for nothing.
Be careful putting the hub back in or else you'll push the inside wheel bearing back out the other side of the spindle. Don't use a slide hammer when reassembling. Use a large socket and a hammer instead since it's easier to keep the hub centred.
Be prepared to remove the whole spindle in case a bearing does pop out.
ps: Hopefully you've got the right rotor for your car. The larger GTi/convertable rotors won't work with the rest of the '89-94 models. Make sure you check and compare before doing major surgery on your car.
