Solution

1. Preparation

Gather tools and parts, ensuring the vehicle is parked on a level surface.
Disconnect the battery for safety.
Tools Required: Jack, jack stands, socket set, torque wrench, wheel bearing puller, grease, and a hammer.

2. Remove the Wheel

Loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely and set it aside.

3. Remove the Brake Components

Remove the brake caliper by unbolting it from the bracket. Hang it using a bungee cord to avoid stress on the brake line.
Remove the brake rotor from the wheel hub by pulling it off the hub assembly.

4. Remove the Wheel Hub Assembly

Remove any retaining clips or bolts securing the wheel hub assembly.
Use a wheel bearing puller to carefully extract the wheel hub from the spindle.
Inspect the hub for wear or damage before proceeding.

5. Install New Wheel Bearings

Clean the hub and apply fresh grease to the new wheel bearings.
Press the new wheel bearings into the wheel hub using the appropriate tools.
Reinstall the wheel hub assembly onto the spindle, securing it with the bolts to the manufacturer’s torque specifications.

6. Reassemble Components

Reinstall the brake rotor and caliper.
Ensure the caliper bolts are tightened to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle from the jack stands.
Torque the lug nuts to the specified value using a torque wrench.
