Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, and grease.

2. Remove the Wheel

Use the lug wrench to loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
- Note: Support the caliper with a wire hanger to avoid stress on the brake line.
Take off the brake rotor by removing any retaining screws or clips.

4. Remove the Wheel Hub Assembly

Remove the hub nut in the center of the wheel hub using a socket wrench.
If applicable, detach any ABS sensor wires connected to the hub.
Use a wheel bearing puller to carefully extract the wheel hub assembly from the knuckle.

5. Install New Wheel Bearing

Clean the wheel hub assembly area and apply a thin layer of grease where the new bearing will sit.
Press the new wheel bearing into the hub using a bearing press or mallet (ensure it is seated evenly).
Reattach the hub assembly to the vehicle knuckle, securing it with the hub nut to the manufacturer’s torque specifications.

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and secure it with any retaining screws or clips.
Reattach the brake caliper and tighten the caliper bolts to the specified torque.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.

7. Final Steps

Reconnect the negative battery terminal.
Check the wheel alignment if necessary.
