Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe place to avoid losing them.

4. Remove the Brake Caliper and Rotor

Remove the caliper mounting bolts using the appropriate socket size.
Carefully hang the brake caliper using a bungee cord or wire to avoid stressing the brake line.
Remove the brake rotor by sliding it off the hub.

5. Remove the Wheel Bearing

Remove any retaining rings or clips securing the wheel bearing to the hub assembly.
Use a bearing puller to carefully extract the wheel bearing from the hub.
Inspect the hub for any signs of damage or wear.

6. Install New Wheel Bearing

Press the new wheel bearing into the hub using a bearing press.
Ensure it is seated correctly and secure with any retaining rings or clips.

7. Reassemble Components

Reinstall the brake rotor and caliper.
Ensure caliper bolts are tightened to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

8. Lower the Vehicle and Finalize

Lower the vehicle off the jack stands using the hydraulic jack.
Tighten the lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs).
Reconnect the negative battery terminal.
