Solution

1. Preparation

Gather tools and parts required for the replacement.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves.

2. Remove Wheel and Brake Components

Loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.
Remove the brake caliper by unscrewing the caliper bolts using a socket set. Hang the caliper using a bungee cord to avoid strain on the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

3. Access the Wheel Bearing

Remove the dust cap or the retaining ring from the hub assembly if applicable.
Unbolt the hub assembly from the knuckle using a socket set.
Disconnect any ABS sensor wiring if present, carefully unclipping it from its mount.

4. Replace the Wheel Bearing

Use a wheel bearing press or a suitable puller to remove the old bearing from the hub assembly.
Clean the hub surface thoroughly before installing the new bearing.
Apply a light coat of grease to the new bearing's outer surface and press it into the hub assembly using a bearing press.

5. Reassemble Components

Reinstall the hub assembly back onto the knuckle and secure it with bolts, tightening them to the manufacturer’s specified torque.
Reconnect the ABS sensor wiring if applicable.
Install the brake rotor and secure it with retaining screws.
Reattach the brake caliper and tighten the caliper bolts to the specified torque.
Mount the wheel back onto the hub and hand-tighten the lug nuts.

6. Lower the Vehicle and Finalize

Lower the vehicle from the jack stands using the jack.
Tighten the lug nuts to the specified torque in a crisscross pattern.
Replace the dust cap or retaining ring if removed.
