Step-by-Step Approach

1. Safety First: Engage the parking brake, place the vehicle in park, and lift it securely on axle stands.
2. Remove the Tire: Loosen and remove the lug nuts, then carefully remove the tire.
3. Disconnect the Caliper: Use a caliper compressor to retract the pistons and detach the brake caliper.
4. Disconnect the Ball Joint: Separate the ball joint from the steering knuckle using a ball joint separator.
5. Remove the Hub Assembly: Utilize a puller to detach the hub assembly from the spindle.
6. Extraction and Installation: Hammer out the old bearing and drive in the new one using a slide hammer.
7. Reassemble: Reinstall the hub assembly onto the spindle, reconnect the ball joint, and mount the caliper.
8. Tighten to Torque: Use a torque wrench to tighten all bolts to the specified torque.
9. Inspect and Test: Double-check all connections and test drive the vehicle to ensure smooth operation.
