you'll need to remove the hub assembly, remove the driveshaft centre nut, undo the 3 bolts that hold the balljoint to the wishnone (remember to mark the position as the 3 bolts alter the caster, camber, tracking etc), undo the track rod end, suspension strut. press the hub out, press the bearing out, and press the new bearing and hub back in, you may be able to remove the hub and bearing with a puller, and install the same way, but a hydraulic press is far easier
