Park the car on level ground. Put the transmission in park and set the parking brake. Jack the car up and place the jack stands underneath the frame of the car.
Use the tire iron to remove the lug nuts from the wheel and pull the wheel off.
Use the ratchet set to remove the mounting screws on the disc brake caliper. Pull the caliper loose and then slide the disc off of the wheel studs.
Use the ratchet to loosen and remove the wheel hub mounting bolts located on the backside of the steering spindle.
Pull the entire wheel hub assembly off of the steering spindle. Take the assembly to a machine shop and have them use a hydraulic press to press out your bearing (the bearing is pressed into the hub assembly and is too big for at-home extraction).
Press in the new wheel bearings and then reassemble the wheel hub by mounting it on the steering spindle again.
Slide the disc back into place on the wheel studs and then remount the caliper with the mounting bolts. Slide the wheel back in place on the studs and tighten down the lug nuts in a star pattern.
Lower the car off of the jack stands or move on to change the other side's wheel bearings
