How do you change the rear wheel bearing on a 2000 ford focus wagon?

To change the rear wheel bearing on a 2000 Ford Focus wagon, first, safely lift the vehicle and remove the rear wheel. Then, detach the brake caliper and rotor, followed by the axle nut if necessary. Use a bearing puller to remove the old bearing from the hub assembly, clean the area, and press in the new bearing. Reassemble the components in reverse order, ensuring everything is properly torqued and secure before lowering the vehicle.
