Solution

1. Preparation

Gather Tools:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Wheel bearing puller
Safety Precautions:
- Wear safety glasses and gloves.
- Ensure the vehicle is on a flat, level surface before lifting.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely and set it aside.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts.
Hang the caliper using a wire to avoid strain on the brake line.
Remove the brake rotor by unscrewing any retaining screws if applicable.

4. Remove Hub Assembly

Remove any dust caps or retaining clips from the hub assembly.
Unscrew the hub assembly bolts using a socket set.
Use a wheel bearing puller to extract the hub assembly from the knuckle.

5. Install New Bearing

Clean the hub mounting area thoroughly.
Place the new wheel bearing in position and press it into the hub assembly using a suitable tool.
Reinstall the hub assembly onto the knuckle and secure it with bolts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

6. Reassemble Components

Reinstall the brake rotor and caliper, ensuring that all bolts are tightened to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle

Carefully lower the vehicle back to the ground and use the torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually around 140-160 ft-lbs).
