Jack up the car, remove the tire, you'll need to remove the axleshaft nut, disconnect the strut from the wheel hub. You can pull the wheel hub towards you. This should give you enough room to get the outer CV joint out of the hub, you may need to take off the brake caliper, and tie it back for more room. You'll need to use a pry bar to pop out the inner CV joint out of the transmission. Some stores rent a tool to use to remove the inner CV joint from the transmission.
