you have to take the axle nut out take the 4 bolts off in back of the knuckle and beat the hub off it's not recommended to DIY because if you don't know what your doing you can screw it up big time and be without a car. I recommend taking it to the pros. or pulling the while spindle off and having a machine shop press them out. we use a special in car press to take them out. if money is a issue just replace the pads and deal with warpped rotors until you can fix it.
