Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal for safety.
Gather tools and parts required for the job.

2. Raise the Vehicle

Use a floor jack to lift the vehicle and secure it on jack stands.
Remove the wheel corresponding to the faulty bearing.

3. Remove Brake Components

Remove the caliper by unbolting it from the bracket using a socket set.
Suspend the caliper with a bungee cord to avoid stress on the brake line.
Take off the brake rotor by removing the retaining screws.

4. Remove Hub Assembly

Remove the hub assembly nut using a socket and ratchet.
If necessary, use a hub puller to detach the hub from the axle.
Inspect the bearing for damage and replace if necessary.

5. Install New Wheel Bearing

Install the new wheel bearing into the hub assembly, ensuring it is seated properly.
Reattach the hub to the axle and torque the hub assembly nut to the manufacturer's specifications (typically 150-200 ft-lbs).
Reinstall the brake rotor and caliper, ensuring all bolts are torqued correctly (caliper bolts 30-40 ft-lbs).

6. Reassemble and Lower Vehicle

Reinstall the wheel and torque lug nuts to the manufacturer's specifications (usually 85-100 ft-lbs).
Reconnect the negative battery terminal.
Lower the vehicle from jack stands using the floor jack.
